Rework LLDB system initialization. In an effort to reduce binary size for components not wishing to link against all of LLDB, as well as a parallel effort to reduce link dependencies on Python, this patch splits out the notion of LLDB initialization into "full" and "common" initialization. All code related to initializing the full LLDB suite lives directly in API now. Previously it was only referenced from API, but because it was defined in lldbCore, it would get implicitly linked against by everything including lldb-server, causing a considerable increase in binary size. By moving this to the API layer, it also creates a better layering for the ongoing effort to make the embedded interpreter replacable with one from a different language (or even be completely removeable). One semantic change necessary to get this all working was to remove the notion of a shared debugger refcount. The debugger is either initialized or uninitialized now, and calling Initialize() multiple times will simply have no effect, while the first Terminate() will now shut it down no matter how many times Initialize() was called. This behaves nicely with all of our supported usage patterns though, and allows us to fix a number of nasty hacks from before. Differential Revision: http://reviews.llvm.org/D8462 llvm-svn: 233758

Update the file headers across all of the LLVM projects in the monorepo to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

Move SystemInitializerFull header to source/API Summary: It seems to me that files in include/lldb/API/ are headers that should be exposed to liblldb users. Because SystemInitializerFull.h exposes details of lldb_private, I think having it there is not the right thing to do. Since it's only included from files in source/API, we should move it there and treat it as private.

Convert the ScriptInterpreter system to a plugin-based one. Previously embedded interpreters were handled as ad-hoc source files compiled into source/Interpreter. This made it hard to disable a specific interpreter, or to add support for other interpreters and allow the developer to choose which interpreter(s) were enabled for a particular build. This patch converts script interpreters over to a plugin-based system. Script interpreters now live in source/Plugins/ScriptInterpreter, and the canonical LLDB interpreter, ScriptInterpreterPython, is moved there as well. Any new code interfacing with the Python C API must live in this location from here on out. Additionally, generic code should never need to reference or make assumptions about the presence of a specific interpreter going forward.

TypeSystem is now a plugin interface and removed any "ClangASTContext &Class::GetClangASTContext()" functions. This cleans up type systems to be more pluggable. Prior to this we had issues: - Module, SymbolFile, and many others has "ClangASTContext &GetClangASTContext()" functions. All have been switched over to use "TypeSystem *GetTypeSystemForLanguage()" - Cleaned up any places that were using the GetClangASTContext() functions to use TypeSystem - Cleaned up Module so that it no longer has dedicated type system member variables: lldb::ClangASTContextUP m_ast; ///< The Clang AST context for this module. lldb::GoASTContextUP m_go_ast; ///< The Go AST context for this module. Now we have a type system map: typedef std::map<lldb::LanguageType, lldb::TypeSystemSP> TypeSystemMap; TypeSystemMap m_type_system_map; ///< A map of any type systems associated with this module - Many places in code were using ClangASTContext static functions to place with CompilerType objects and add modifiers (const, volatile, restrict) and to make typedefs, L and R value references and more. These have been made into CompilerType functions that are abstract: class CompilerType { ... //---------------------------------------------------------------------- // Return a new CompilerType that is a L value reference to this type if // this type is valid and the type system supports L value references, // else return an invalid type. //---------------------------------------------------------------------- CompilerType GetLValueReferenceType () const; //---------------------------------------------------------------------- // Return a new CompilerType that is a R value reference to this type if // this type is valid and the type system supports R value references, // else return an invalid type. //---------------------------------------------------------------------- CompilerType GetRValueReferenceType () const; //---------------------------------------------------------------------- // Return a new CompilerType adds a const modifier to this type if // this type is valid and the type system supports const modifiers, // else return an invalid type. //---------------------------------------------------------------------- CompilerType AddConstModifier () const; //---------------------------------------------------------------------- // Return a new CompilerType adds a volatile modifier to this type if // this type is valid and the type system supports volatile modifiers, // else return an invalid type. //---------------------------------------------------------------------- CompilerType AddVolatileModifier () const; //---------------------------------------------------------------------- // Return a new CompilerType adds a restrict modifier to this type if // this type is valid and the type system supports restrict modifiers, // else return an invalid type. //---------------------------------------------------------------------- CompilerType AddRestrictModifier () const; //---------------------------------------------------------------------- // Create a typedef to this type using "name" as the name of the typedef // this type is valid and the type system supports typedefs, else return // an invalid type. //---------------------------------------------------------------------- CompilerType CreateTypedef (const char *name, const CompilerDeclContext &decl_ctx) const; }; Other changes include: - Removed "CompilerType TypeSystem::GetIntTypeFromBitSize(...)" and CompilerType TypeSystem::GetFloatTypeFromBitSize(...) and replaced it with "CompilerType TypeSystem::GetBuiltinTypeForEncodingAndBitSize(lldb::Encoding encoding, size_t bit_size);" - Fixed code in Type.h to not request the full type for a type for no good reason, just request the forward type and let the type expand as needed llvm-svn: 247953

Add support for reading line tables from PDB files. PDB is Microsoft's debug information format, and although we cannot yet generate it, we still must be able to consume it. Reason for this is that debug information for system libraries (e.g. kernel32, C Runtime Library, etc) only have debug info in PDB format, so in order to be able to support debugging of system code, we must support it. Currently this code should compile on every platform, but on non-Windows platforms the PDB plugin will return 0 capabilities, meaning that for now PDB is only supported on Windows. This may change in the future, but the API is designed in such a way that this will require few (if any) changes on the LLDB side. In the future we can just flip a switch and everything will work. This patch only adds support for line tables. It does not return information about functions, types, global variables, or anything else. This functionality will be added in a followup patch.

Support Linux on SystemZ as platform This patch adds support for Linux on SystemZ: - A new ArchSpec value of eCore_s390x_generic - A new directory Plugins/ABI/SysV-s390x providing an ABI implementation - Register context support - Native Linux support including watchpoint support - ELF core file support - Misc. support throughout the code base (e.g. breakpoint opcodes) - Test case updates to support the platform This should provide complete support for debugging the SystemZ platform. Not yet supported are optional features like transaction support (zEC12) or SIMD vector support (z13). There is no instruction emulation, since our ABI requires that all code provide correct DWARF CFI at all PC locations in .eh_frame to support unwinding (i.e. -fasynchronous-unwind-tables is on by default). The implementation follows existing platforms in a mostly straightforward manner. A couple of things that are different: - We do not use PTRACE_PEEKUSER / PTRACE_POKEUSER to access single registers, since some registers (access register) reside at offsets in the user area that are multiples of 4, but the PTRACE_PEEKUSER interface only allows accessing aligned 8-byte blocks in the user area. Instead, we use a s390 specific ptrace interface PTRACE_PEEKUSR_AREA / PTRACE_POKEUSR_AREA that allows accessing a whole block of the user area in one go, so in effect allowing to treat parts of the user area as register sets. - SystemZ hardware does not provide any means to implement read watchpoints, only write watchpoints. In fact, we can only support a *single* write watchpoint (but this can span a range of arbitrary size). In LLDB this means we support only a single watchpoint. I've set all test cases that require read watchpoints (or multiple watchpoints) to expected failure on the platform. [ Note that there were two test cases that install a read/write watchpoint even though they nowhere rely on the "read" property. I've changed those to simply use plain write watchpoints. ] Differential Revision: http://reviews.llvm.org/D18978 llvm-svn: 266308

Add a new DynamicLoader plugin that uses SPI that are in development for the fall (northern hemisphere) 2016 Darwin platforms to learn about loaded images, instead of reading dyld internal data structures. These new SPI don't exist on older releases, and new packets are needed from debugserver to use them (those changes are already committed). I had to change the minimum deployment target for debugserver in the xcode project file to macOS 10.10 so that debugserver will use the [[NSProcessInfo processInfo] operatingSystemVersion] call in MachProcess::GetOSVersionNumbers to get the operarting system version # -- this API is only available in macOS 10.10 and newer ("OS X Yosemite", released Oct 2014). If we have many people building llvm.org lldb on older systems still, we can back off on this for the llvm.org sources. There should be no change in behavior with this commit, either to older darwin systems or newer darwin systems. For now the new DynamicLoader plugin is never activated - I'm forcing the old plugin to be used in DynamicLoaderDarwin::UseDYLDSPI. I'll remove that unconditional use of the old plugin soon, so the newer plugin is used on the newest Darwin platforms. <rdar://problem/25251243> llvm-svn: 276254

Rework LLDB system initialization. In an effort to reduce binary size for components not wishing to link against all of LLDB, as well as a parallel effort to reduce link dependencies on Python, this patch splits out the notion of LLDB initialization into "full" and "common" initialization. All code related to initializing the full LLDB suite lives directly in API now. Previously it was only referenced from API, but because it was defined in lldbCore, it would get implicitly linked against by everything including lldb-server, causing a considerable increase in binary size. By moving this to the API layer, it also creates a better layering for the ongoing effort to make the embedded interpreter replacable with one from a different language (or even be completely removeable). One semantic change necessary to get this all working was to remove the notion of a shared debugger refcount. The debugger is either initialized or uninitialized now, and calling Initialize() multiple times will simply have no effect, while the first Terminate() will now shut it down no matter how many times Initialize() was called. This behaves nicely with all of our supported usage patterns though, and allows us to fix a number of nasty hacks from before. Differential Revision: http://reviews.llvm.org/D8462 llvm-svn: 233758

Add support for language plugins to provide data formatters (second attempt) Historically, data formatters all exist in a global repository (the category map) On top of that, some formatters can be "hardcoded" when the conditions under which they apply are not expressible as a typename (or typename regex) This change paves the way to move formatters into per-language buckets such that the C++ plugin is responsible for ownership of the C++ formatters, and so on The advantages of this are: a) language formatters only get created when they might apply b) formatters for a language are clearly owned by the matching language plugin The current model is one of static instantiation, that is a language knows the full set of formatters it vends and that is only asked-for once, and then handed off to the FormatManager In a future revision it might be interesting to add similar ability to the language runtimes, and monitor for certain shared library events to add even more library-specific formatters No formatters are moved as part of this change, so practically speaking this is NFC llvm-svn: 246568

Add support for reading line tables from PDB files. PDB is Microsoft's debug information format, and although we cannot yet generate it, we still must be able to consume it. Reason for this is that debug information for system libraries (e.g. kernel32, C Runtime Library, etc) only have debug info in PDB format, so in order to be able to support debugging of system code, we must support it. Currently this code should compile on every platform, but on non-Windows platforms the PDB plugin will return 0 capabilities, meaning that for now PDB is only supported on Windows. This may change in the future, but the API is designed in such a way that this will require few (if any) changes on the LLDB side. In the future we can just flip a switch and everything will work. This patch only adds support for line tables. It does not return information about functions, types, global variables, or anything else. This functionality will be added in a followup patch.

Re-commit "Introduce ObjectFileBreakpad" This re-commits r348592, which was reverted due to a failing test on macos. The issue was that I was passing a null pointer for the "CreateMemoryInstance" callback when registering ObjectFileBreakpad, which caused crashes when attemping to load modules from memory. The correct thing to do is to pass a callback which always returns a null pointer (as breakpad files are never loaded in inferior memory). It turns out that there is only one test which exercises this code path, and it's mac-only, so I've create a new test which should run everywhere (except windows, as one cannot delete an executable which is being run). Unfortunately, this test still fails on linux for other reasons, but at least it gives us something to aim for. The original commit message was: This patch adds the scaffolding necessary for lldb to recognise symbol files generated by breakpad. These (textual) files contain just enough information to be able to produce a backtrace from a crash dump. This information includes: - UUID, architecture and name of the module - line tables - list of symbols - unwind information A minimal breakpad file could look like this: MODULE Linux x86_64 0000000024B5D199F0F766FFFFFF5DC30 a.out INFO CODE_ID 00000000B52499D1F0F766FFFFFF5DC3 FILE 0 /tmp/a.c FUNC 1010 10 0 _start 1010 4 4 0 1014 5 5 0 1019 5 6 0 101e 2 7 0 PUBLIC 1010 0 _start STACK CFI INIT 1010 10 .cfa: $rsp 8 + .ra: .cfa -8 + ^ STACK CFI 1011 $rbp: .cfa -16 + ^ .cfa: $rsp 16 + STACK CFI 1014 .cfa: $rbp 16 + Even though this data would normally be considered "symbol" information, in the current lldb infrastructure it is assumed every SymbolFile object is backed by an ObjectFile instance. So, in order to better interoperate with the rest of the code (particularly symbol vendors). In this patch I just parse the breakpad header, which is enough to populate the UUID and architecture fields of the ObjectFile interface. The rough plan for followup patches is to expose the individual parts of the breakpad file as ObjectFile "sections", which can then be used by other parts of the codebase (SymbolFileBreakpad ?) to vend the necessary information.

Move ObjectFile initialization out of SystemInitializerCommon Summary: For lldb-server, it is sufficient to parse only the native object file format for its target OS (no other file can be loaded into a running process). This moves the object file initialization code into specific initializer classes: lldb-test and liblldb get all object files; lldb-server gets only one of them. For this to work, I've needed to create a special SystemInitializer for use in lldb-server, instead of it calling directly into the common one. This reduces the size of lldb-server by about 2%, which is not earth-shattering, but it's an easy win, and it helps.

This is because I have only written register contexts for those. Others will come in next CLs. I copied the WinMinidump tests and adapted them a little bit for them to work with the new plugin (and they pass) I will add more tests, aiming for better code coverage.

This made it hard to disable a specific interpreter, or to add support for other interpreters and allow the developer to choose which interpreter(s) were enabled for a particular build. This patch converts script interpreters over to a plugin-based system. Script interpreters now live in source/Plugins/ScriptInterpreter, and the canonical LLDB interpreter, ScriptInterpreterPython, is moved there as well. Any new code interfacing with the Python C API must live in this location from here on out. Additionally, generic code should never need to reference or make assumptions about the presence of a specific interpreter going forward.

Introduce SymbolFileBreakpad and use it to fill symtab Summary: This commit adds the glue code necessary to integrate the SymbolFileBreakpad into the plugin system. Most of the methods are stubbed out. The only method implemented method is AddSymbols, which parses the PUBLIC "section" of the breakpad "object file", and fills out the Module's symtab. To enable testing this, I've made two additional changes: - dump Symtab from the SymbolVendor class. The symtab was already being dumped as a part of the object file dump, but that happened before symbol vendor kicked in, so it did not reflect any symbols added there. - add ability to explicitly specify the external symbol file in lldb-test (so that the object file could be linked with the breakpad symbol file). To make things simpler, I've changed lldb-test from consuming multiple inputs (and dumping their symbols) to having it just process a single file per invocation. This was not a problem since everyone was using it that way already.

Rework LLDB system initialization. In an effort to reduce binary size for components not wishing to link against all of LLDB, as well as a parallel effort to reduce link dependencies on Python, this patch splits out the notion of LLDB initialization into "full" and "common" initialization. All code related to initializing the full LLDB suite lives directly in API now. Previously it was only referenced from API, but because it was defined in lldbCore, it would get implicitly linked against by everything including lldb-server, causing a considerable increase in binary size. By moving this to the API layer, it also creates a better layering for the ongoing effort to make the embedded interpreter replacable with one from a different language (or even be completely removeable). One semantic change necessary to get this all working was to remove the notion of a shared debugger refcount. The debugger is either initialized or uninitialized now, and calling Initialize() multiple times will simply have no effect, while the first Terminate() will now shut it down no matter how many times Initialize() was called. This behaves nicely with all of our supported usage patterns though, and allows us to fix a number of nasty hacks from before. Differential Revision: http://reviews.llvm.org/D8462 llvm-svn: 233758

Refactor LLDB's Windows process plugin (NFC) The Windows process plugin was broken up into multiple pieces a while back in order to share code between debugging live processes and minidumps (postmortem) debugging. The minidump portion was replaced by a cross-platform solution. This left the plugin split into a formerly "common" base classes and the derived classes for live debugging. This extra layer made the code harder to understand and work with. This patch simplifies these class hierarchies by rolling the live debugging concrete classes up to the base classes. Last week I posted my intent to make this change to lldb-dev, and I didn't hear any objections. This involved moving code and changing references to classes like ProcessWindowsLive to ProcessWindows. It still builds for both 32- and 64-bit, and the tests still pass on 32-bit. (Tests on 64-bit weren't passing before this refactor for unrelated reasons.) llvm-svn: 287770

[Reproducers] Change how reproducers are initialized. This patch changes the way the reproducer is initialized. Rather than making changes at run time we now do everything at initialization time. To make this happen we had to introduce initializer options and their SB variant. This allows us to tell the initializer that we're running in reproducer capture/replay mode. Because of this change we also had to alter our testing strategy. We cannot reinitialize LLDB when using the dotest infrastructure. Instead we use lit and invoke two instances of the driver. Another consequence is that we can no longer enable capture or replay through commands. This was bound to go away form the beginning, but I had something in mind where you could enable/disable specific providers. However this seems like it adds very little value right now so the corresponding commands were removed. Finally this change also means you now have to control this through the driver, for which I replaced --reproducer with --capture and --replay to differentiate between the two modes.

Move ObjectFile initialization out of SystemInitializerCommon Summary: For lldb-server, it is sufficient to parse only the native object file format for its target OS (no other file can be loaded into a running process). This moves the object file initialization code into specific initializer classes: lldb-test and liblldb get all object files; lldb-server gets only one of them. For this to work, I've needed to create a special SystemInitializer for use in lldb-server, instead of it calling directly into the common one. This reduces the size of lldb-server by about 2%, which is not earth-shattering, but it's an easy win, and it helps.

Re-commit "Introduce ObjectFileBreakpad" This re-commits r348592, which was reverted due to a failing test on macos. The issue was that I was passing a null pointer for the "CreateMemoryInstance" callback when registering ObjectFileBreakpad, which caused crashes when attemping to load modules from memory. The correct thing to do is to pass a callback which always returns a null pointer (as breakpad files are never loaded in inferior memory). It turns out that there is only one test which exercises this code path, and it's mac-only, so I've create a new test which should run everywhere (except windows, as one cannot delete an executable which is being run). Unfortunately, this test still fails on linux for other reasons, but at least it gives us something to aim for. The original commit message was: This patch adds the scaffolding necessary for lldb to recognise symbol files generated by breakpad. These (textual) files contain just enough information to be able to produce a backtrace from a crash dump. This information includes: - UUID, architecture and name of the module - line tables - list of symbols - unwind information A minimal breakpad file could look like this: MODULE Linux x86_64 0000000024B5D199F0F766FFFFFF5DC30 a.out INFO CODE_ID 00000000B52499D1F0F766FFFFFF5DC3 FILE 0 /tmp/a.c FUNC 1010 10 0 _start 1010 4 4 0 1014 5 5 0 1019 5 6 0 101e 2 7 0 PUBLIC 1010 0 _start STACK CFI INIT 1010 10 .cfa: $rsp 8 + .ra: .cfa -8 + ^ STACK CFI 1011 $rbp: .cfa -16 + ^ .cfa: $rsp 16 + STACK CFI 1014 .cfa: $rbp 16 + Even though this data would normally be considered "symbol" information, in the current lldb infrastructure it is assumed every SymbolFile object is backed by an ObjectFile instance. So, in order to better interoperate with the rest of the code (particularly symbol vendors). In this patch I just parse the breakpad header, which is enough to populate the UUID and architecture fields of the ObjectFile interface. The rough plan for followup patches is to expose the individual parts of the breakpad file as ObjectFile "sections", which can then be used by other parts of the codebase (SymbolFileBreakpad ?) to vend the necessary information.

Yet, the defitions themselves span nearly 10kLOC. The two users are: - dwarf expression pretty printer - the mechanism for augmenting the register info definitions obtained over gdb-remote protocol (AugmentRegisterInfoViaABI) Both of these uses need the DWARF an EH register numbers, which is information that is already available in LLVM. This patch makes it possible to do so. It adds a GetMCRegisterInfo method to the ABI class, which every class is expected to implement. Normally, it should be sufficient to obtain the definitions from the appropriate llvm::Target object (for which I provide a utility function), but the subclasses are free to construct it in any way they deem fit. We should be able to always get the MCRegisterInfo object from llvm, with one important exception: if the relevant llvm target was disabled at compile time. To handle this, I add a mechanism to disable the compilation of ABI plugins based on the value of LLVM_TARGETS_TO_BUILD cmake setting. This ensures all our existing are able to create their MCRegisterInfo objects. The new MCRegisterInfo api is not used yet, but the intention is to make use of it in follow-up patches.

Rework LLDB system initialization. In an effort to reduce binary size for components not wishing to link against all of LLDB, as well as a parallel effort to reduce link dependencies on Python, this patch splits out the notion of LLDB initialization into "full" and "common" initialization. All code related to initializing the full LLDB suite lives directly in API now. Previously it was only referenced from API, but because it was defined in lldbCore, it would get implicitly linked against by everything including lldb-server, causing a considerable increase in binary size. By moving this to the API layer, it also creates a better layering for the ongoing effort to make the embedded interpreter replacable with one from a different language (or even be completely removeable). One semantic change necessary to get this all working was to remove the notion of a shared debugger refcount. The debugger is either initialized or uninitialized now, and calling Initialize() multiple times will simply have no effect, while the first Terminate() will now shut it down no matter how many times Initialize() was called. This behaves nicely with all of our supported usage patterns though, and allows us to fix a number of nasty hacks from before. Differential Revision: http://reviews.llvm.org/D8462 llvm-svn: 233758

Support Linux on SystemZ as platform This patch adds support for Linux on SystemZ: - A new ArchSpec value of eCore_s390x_generic - A new directory Plugins/ABI/SysV-s390x providing an ABI implementation - Register context support - Native Linux support including watchpoint support - ELF core file support - Misc. support throughout the code base (e.g. breakpoint opcodes) - Test case updates to support the platform This should provide complete support for debugging the SystemZ platform. Not yet supported are optional features like transaction support (zEC12) or SIMD vector support (z13). There is no instruction emulation, since our ABI requires that all code provide correct DWARF CFI at all PC locations in .eh_frame to support unwinding (i.e. -fasynchronous-unwind-tables is on by default). The implementation follows existing platforms in a mostly straightforward manner. A couple of things that are different: - We do not use PTRACE_PEEKUSER / PTRACE_POKEUSER to access single registers, since some registers (access register) reside at offsets in the user area that are multiples of 4, but the PTRACE_PEEKUSER interface only allows accessing aligned 8-byte blocks in the user area. Instead, we use a s390 specific ptrace interface PTRACE_PEEKUSR_AREA / PTRACE_POKEUSR_AREA that allows accessing a whole block of the user area in one go, so in effect allowing to treat parts of the user area as register sets. - SystemZ hardware does not provide any means to implement read watchpoints, only write watchpoints. In fact, we can only support a *single* write watchpoint (but this can span a range of arbitrary size). In LLDB this means we support only a single watchpoint. I've set all test cases that require read watchpoints (or multiple watchpoints) to expected failure on the platform. [ Note that there were two test cases that install a read/write watchpoint even though they nowhere rely on the "read" property. I've changed those to simply use plain write watchpoints. ] Differential Revision: http://reviews.llvm.org/D18978 llvm-svn: 266308

This is because I have only written register contexts for those. Others will come in next CLs. I copied the WinMinidump tests and adapted them a little bit for them to work with the new plugin (and they pass) I will add more tests, aiming for better code coverage.

Introduce SymbolFileBreakpad and use it to fill symtab Summary: This commit adds the glue code necessary to integrate the SymbolFileBreakpad into the plugin system. Most of the methods are stubbed out. The only method implemented method is AddSymbols, which parses the PUBLIC "section" of the breakpad "object file", and fills out the Module's symtab. To enable testing this, I've made two additional changes: - dump Symtab from the SymbolVendor class. The symtab was already being dumped as a part of the object file dump, but that happened before symbol vendor kicked in, so it did not reflect any symbols added there. - add ability to explicitly specify the external symbol file in lldb-test (so that the object file could be linked with the breakpad symbol file). To make things simpler, I've changed lldb-test from consuming multiple inputs (and dumping their symbols) to having it just process a single file per invocation. This was not a problem since everyone was using it that way already.

SymbolFileDWARF::Initialize();
Add support for reading line tables from PDB files. PDB is Microsoft's debug information format, and although we cannot yet generate it, we still must be able to consume it. Reason for this is that debug information for system libraries (e.g. kernel32, C Runtime Library, etc) only have debug info in PDB format, so in order to be able to support debugging of system code, we must support it. Currently this code should compile on every platform, but on non-Windows platforms the PDB plugin will return 0 capabilities, meaning that for now PDB is only supported on Windows. This may change in the future, but the API is designed in such a way that this will require few (if any) changes on the LLDB side. In the future we can just flip a switch and everything will work.

Rework LLDB system initialization. In an effort to reduce binary size for components not wishing to link against all of LLDB, as well as a parallel effort to reduce link dependencies on Python, this patch splits out the notion of LLDB initialization into "full" and "common" initialization. All code related to initializing the full LLDB suite lives directly in API now. Previously it was only referenced from API, but because it was defined in lldbCore, it would get implicitly linked against by everything including lldb-server, causing a considerable increase in binary size. By moving this to the API layer, it also creates a better layering for the ongoing effort to make the embedded interpreter replacable with one from a different language (or even be completely removeable). One semantic change necessary to get this all working was to remove the notion of a shared debugger refcount. The debugger is either initialized or uninitialized now, and calling Initialize() multiple times will simply have no effect, while the first Terminate() will now shut it down no matter how many times Initialize() was called. This behaves nicely with all of our supported usage patterns though, and allows us to fix a number of nasty hacks from before. Differential Revision: http://reviews.llvm.org/D8462 llvm-svn: 233758

Add support for language plugins to provide data formatters (second attempt) Historically, data formatters all exist in a global repository (the category map) On top of that, some formatters can be "hardcoded" when the conditions under which they apply are not expressible as a typename (or typename regex) This change paves the way to move formatters into per-language buckets such that the C++ plugin is responsible for ownership of the C++ formatters, and so on The advantages of this are: a) language formatters only get created when they might apply b) formatters for a language are clearly owned by the matching language plugin The current model is one of static instantiation, that is a language knows the full set of formatters it vends and that is only asked-for once, and then handed off to the FormatManager In a future revision it might be interesting to add similar ability to the language runtimes, and monitor for certain shared library events to add even more library-specific formatters No formatters are moved as part of this change, so practically speaking this is NFC llvm-svn: 246568

Refactor LLDB's Windows process plugin (NFC) The Windows process plugin was broken up into multiple pieces a while back in order to share code between debugging live processes and minidumps (postmortem) debugging. The minidump portion was replaced by a cross-platform solution. This left the plugin split into a formerly "common" base classes and the derived classes for live debugging. This extra layer made the code harder to understand and work with. This patch simplifies these class hierarchies by rolling the live debugging concrete classes up to the base classes. Last week I posted my intent to make this change to lldb-dev, and I didn't hear any objections. This involved moving code and changing references to classes like ProcessWindowsLive to ProcessWindows. It still builds for both 32- and 64-bit, and the tests still pass on 32-bit. (Tests on 64-bit weren't passing before this refactor for unrelated reasons.) llvm-svn: 287770

DynamicLoaderMacOSXDYLD::Initialize();
Add a new DynamicLoader plugin that uses SPI that are in development for the fall (northern hemisphere) 2016 Darwin platforms to learn about loaded images, instead of reading dyld internal data structures. These new SPI don't exist on older releases, and new packets are needed from debugserver to use them (those changes are already committed). I had to change the minimum deployment target for debugserver in the xcode project file to macOS 10.10 so that debugserver will use the [[NSProcessInfo processInfo] operatingSystemVersion] call in MachProcess::GetOSVersionNumbers to get the operarting system version # -- this API is only available in macOS 10.10 and newer ("OS X Yosemite", released Oct 2014). If we have many people building llvm.org lldb on older systems still, we can back off on this for the llvm.org sources. There should be no change in behavior with this commit, either to older darwin systems or newer darwin systems. For now the new DynamicLoader plugin is never activated - I'm forcing the old plugin to be used in DynamicLoaderDarwin::UseDYLDSPI. I'll remove that unconditional use of the old plugin soon, so the newer plugin is used on the newest Darwin platforms. <rdar://problem/25251243> llvm-svn: 276254

Debugger::SettingsInitialize();
[Reproducers] Change how reproducers are initialized. This patch changes the way the reproducer is initialized. Rather than making changes at run time we now do everything at initialization time. To make this happen we had to introduce initializer options and their SB variant. This allows us to tell the initializer that we're running in reproducer capture/replay mode. Because of this change we also had to alter our testing strategy. We cannot reinitialize LLDB when using the dotest infrastructure. Instead we use lit and invoke two instances of the driver. Another consequence is that we can no longer enable capture or replay through commands. This was bound to go away form the beginning, but I had something in mind where you could enable/disable specific providers. However this seems like it adds very little value right now so the corresponding commands were removed. Finally this change also means you now have to control this through the driver, for which I replaced --reproducer with --capture and --replay to differentiate between the two modes.

Rework LLDB system initialization. In an effort to reduce binary size for components not wishing to link against all of LLDB, as well as a parallel effort to reduce link dependencies on Python, this patch splits out the notion of LLDB initialization into "full" and "common" initialization. All code related to initializing the full LLDB suite lives directly in API now. Previously it was only referenced from API, but because it was defined in lldbCore, it would get implicitly linked against by everything including lldb-server, causing a considerable increase in binary size. By moving this to the API layer, it also creates a better layering for the ongoing effort to make the embedded interpreter replacable with one from a different language (or even be completely removeable). One semantic change necessary to get this all working was to remove the notion of a shared debugger refcount. The debugger is either initialized or uninitialized now, and calling Initialize() multiple times will simply have no effect, while the first Terminate() will now shut it down no matter how many times Initialize() was called. This behaves nicely with all of our supported usage patterns though, and allows us to fix a number of nasty hacks from before. Differential Revision: http://reviews.llvm.org/D8462 llvm-svn: 233758

TypeSystem is now a plugin interface and removed any "ClangASTContext &Class::GetClangASTContext()" functions. This cleans up type systems to be more pluggable. Prior to this we had issues: - Module, SymbolFile, and many others has "ClangASTContext &GetClangASTContext()" functions. All have been switched over to use "TypeSystem *GetTypeSystemForLanguage()" - Cleaned up any places that were using the GetClangASTContext() functions to use TypeSystem - Cleaned up Module so that it no longer has dedicated type system member variables: lldb::ClangASTContextUP m_ast; ///< The Clang AST context for this module. lldb::GoASTContextUP m_go_ast; ///< The Go AST context for this module. Now we have a type system map: typedef std::map<lldb::LanguageType, lldb::TypeSystemSP> TypeSystemMap; TypeSystemMap m_type_system_map; ///< A map of any type systems associated with this module - Many places in code were using ClangASTContext static functions to place with CompilerType objects and add modifiers (const, volatile, restrict) and to make typedefs, L and R value references and more. These have been made into CompilerType functions that are abstract: class CompilerType { ... //---------------------------------------------------------------------- // Return a new CompilerType that is a L value reference to this type if // this type is valid and the type system supports L value references, // else return an invalid type. //---------------------------------------------------------------------- CompilerType GetLValueReferenceType () const; //---------------------------------------------------------------------- // Return a new CompilerType that is a R value reference to this type if // this type is valid and the type system supports R value references, // else return an invalid type. //---------------------------------------------------------------------- CompilerType GetRValueReferenceType () const; //---------------------------------------------------------------------- // Return a new CompilerType adds a const modifier to this type if // this type is valid and the type system supports const modifiers, // else return an invalid type. //---------------------------------------------------------------------- CompilerType AddConstModifier () const; //---------------------------------------------------------------------- // Return a new CompilerType adds a volatile modifier to this type if // this type is valid and the type system supports volatile modifiers, // else return an invalid type. //---------------------------------------------------------------------- CompilerType AddVolatileModifier () const; //---------------------------------------------------------------------- // Return a new CompilerType adds a restrict modifier to this type if // this type is valid and the type system supports restrict modifiers, // else return an invalid type. //---------------------------------------------------------------------- CompilerType AddRestrictModifier () const; //---------------------------------------------------------------------- // Create a typedef to this type using "name" as the name of the typedef // this type is valid and the type system supports typedefs, else return // an invalid type. //---------------------------------------------------------------------- CompilerType CreateTypedef (const char *name, const CompilerDeclContext &decl_ctx) const; }; Other changes include: - Removed "CompilerType TypeSystem::GetIntTypeFromBitSize(...)" and CompilerType TypeSystem::GetFloatTypeFromBitSize(...) and replaced it with "CompilerType TypeSystem::GetBuiltinTypeForEncodingAndBitSize(lldb::Encoding encoding, size_t bit_size);" - Fixed code in Type.h to not request the full type for a type for no good reason, just request the forward type and let the type expand as needed llvm-svn: 247953

Support Linux on SystemZ as platform This patch adds support for Linux on SystemZ: - A new ArchSpec value of eCore_s390x_generic - A new directory Plugins/ABI/SysV-s390x providing an ABI implementation - Register context support - Native Linux support including watchpoint support - ELF core file support - Misc. support throughout the code base (e.g. breakpoint opcodes) - Test case updates to support the platform This should provide complete support for debugging the SystemZ platform. Not yet supported are optional features like transaction support (zEC12) or SIMD vector support (z13). There is no instruction emulation, since our ABI requires that all code provide correct DWARF CFI at all PC locations in .eh_frame to support unwinding (i.e. -fasynchronous-unwind-tables is on by default). The implementation follows existing platforms in a mostly straightforward manner. A couple of things that are different: - We do not use PTRACE_PEEKUSER / PTRACE_POKEUSER to access single registers, since some registers (access register) reside at offsets in the user area that are multiples of 4, but the PTRACE_PEEKUSER interface only allows accessing aligned 8-byte blocks in the user area. Instead, we use a s390 specific ptrace interface PTRACE_PEEKUSR_AREA / PTRACE_POKEUSR_AREA that allows accessing a whole block of the user area in one go, so in effect allowing to treat parts of the user area as register sets. - SystemZ hardware does not provide any means to implement read watchpoints, only write watchpoints. In fact, we can only support a *single* write watchpoint (but this can span a range of arbitrary size). In LLDB this means we support only a single watchpoint. I've set all test cases that require read watchpoints (or multiple watchpoints) to expected failure on the platform. [ Note that there were two test cases that install a read/write watchpoint even though they nowhere rely on the "read" property. I've changed those to simply use plain write watchpoints. ] Differential Revision: http://reviews.llvm.org/D18978 llvm-svn: 266308

Minidump plugin: Adding ProcessMinidump, ThreadMinidump and register the plugin in SystemInitializerFull Summary: This plugin resembles the already existing Windows-only Minidump plugin. The WinMinidumpPlugin uses the Windows API for parsing Minidumps while this plugin is cross-platform because it includes a Minidump parser (which is already commited) It is able to produce a backtrace, to read the general puprose regiters, inspect local variables, show image list, do memory reads, etc. For now the only arches that this supports are x86_32 and x86_64. This is because I have only written register contexts for those. Others will come in next CLs.

Rework LLDB system initialization. In an effort to reduce binary size for components not wishing to link against all of LLDB, as well as a parallel effort to reduce link dependencies on Python, this patch splits out the notion of LLDB initialization into "full" and "common" initialization. All code related to initializing the full LLDB suite lives directly in API now. Previously it was only referenced from API, but because it was defined in lldbCore, it would get implicitly linked against by everything including lldb-server, causing a considerable increase in binary size. By moving this to the API layer, it also creates a better layering for the ongoing effort to make the embedded interpreter replacable with one from a different language (or even be completely removeable). One semantic change necessary to get this all working was to remove the notion of a shared debugger refcount. The debugger is either initialized or uninitialized now, and calling Initialize() multiple times will simply have no effect, while the first Terminate() will now shut it down no matter how many times Initialize() was called. This behaves nicely with all of our supported usage patterns though, and allows us to fix a number of nasty hacks from before. Differential Revision: http://reviews.llvm.org/D8462 llvm-svn: 233758

Add ThreadSanitizer debugging support. This patch adds ThreadSanitizer support into LLDB: - Adding a new InstrumentationRuntime plugin, ThreadSanitizerRuntime, in the same way ASan is implemented. - A breakpoint stops in `__tsan_on_report`, then we extract all sorts of information by evaluating an expression. We then populate this into StopReasonExtendedInfo. - SBThread gets a new API, SBThread::GetStopReasonExtendedBacktraces(), which returns TSan’s backtraces in the form of regular SBThreads. Non-TSan stop reasons return an empty collection. - Added some test cases. Reviewed by Greg Clayton. llvm-svn: 264162

Introduce SymbolFileBreakpad and use it to fill symtab Summary: This commit adds the glue code necessary to integrate the SymbolFileBreakpad into the plugin system. Most of the methods are stubbed out. The only method implemented method is AddSymbols, which parses the PUBLIC "section" of the breakpad "object file", and fills out the Module's symtab. To enable testing this, I've made two additional changes: - dump Symtab from the SymbolVendor class. The symtab was already being dumped as a part of the object file dump, but that happened before symbol vendor kicked in, so it did not reflect any symbols added there. - add ability to explicitly specify the external symbol file in lldb-test (so that the object file could be linked with the breakpad symbol file). To make things simpler, I've changed lldb-test from consuming multiple inputs (and dumping their symbols) to having it just process a single file per invocation. This was not a problem since everyone was using it that way already.

Add support for reading line tables from PDB files. PDB is Microsoft's debug information format, and although we cannot yet generate it, we still must be able to consume it. Reason for this is that debug information for system libraries (e.g. kernel32, C Runtime Library, etc) only have debug info in PDB format, so in order to be able to support debugging of system code, we must support it. Currently this code should compile on every platform, but on non-Windows platforms the PDB plugin will return 0 capabilities, meaning that for now PDB is only supported on Windows. This may change in the future, but the API is designed in such a way that this will require few (if any) changes on the LLDB side. In the future we can just flip a switch and everything will work. This patch only adds support for line tables. It does not return information about functions, types, global variables, or anything else. This functionality will be added in a followup patch.

Add support for language plugins to provide data formatters (second attempt) Historically, data formatters all exist in a global repository (the category map) On top of that, some formatters can be "hardcoded" when the conditions under which they apply are not expressible as a typename (or typename regex) This change paves the way to move formatters into per-language buckets such that the C++ plugin is responsible for ownership of the C++ formatters, and so on The advantages of this are: a) language formatters only get created when they might apply b) formatters for a language are clearly owned by the matching language plugin The current model is one of static instantiation, that is a language knows the full set of formatters it vends and that is only asked-for once, and then handed off to the FormatManager In a future revision it might be interesting to add similar ability to the language runtimes, and monitor for certain shared library events to add even more library-specific formatters No formatters are moved as part of this change, so practically speaking this is NFC llvm-svn: 246568

Add a new DynamicLoader plugin that uses SPI that are in development for the fall (northern hemisphere) 2016 Darwin platforms to learn about loaded images, instead of reading dyld internal data structures. These new SPI don't exist on older releases, and new packets are needed from debugserver to use them (those changes are already committed). I had to change the minimum deployment target for debugserver in the xcode project file to macOS 10.10 so that debugserver will use the [[NSProcessInfo processInfo] operatingSystemVersion] call in MachProcess::GetOSVersionNumbers to get the operarting system version # -- this API is only available in macOS 10.10 and newer ("OS X Yosemite", released Oct 2014). If we have many people building llvm.org lldb on older systems still, we can back off on this for the llvm.org sources. There should be no change in behavior with this commit, either to older darwin systems or newer darwin systems. For now the new DynamicLoader plugin is never activated - I'm forcing the old plugin to be used in DynamicLoaderDarwin::UseDYLDSPI. I'll remove that unconditional use of the old plugin soon, so the newer plugin is used on the newest Darwin platforms. <rdar://problem/25251243> llvm-svn: 276254

Re-commit "Introduce ObjectFileBreakpad" This re-commits r348592, which was reverted due to a failing test on macos. The issue was that I was passing a null pointer for the "CreateMemoryInstance" callback when registering ObjectFileBreakpad, which caused crashes when attemping to load modules from memory. The correct thing to do is to pass a callback which always returns a null pointer (as breakpad files are never loaded in inferior memory). It turns out that there is only one test which exercises this code path, and it's mac-only, so I've create a new test which should run everywhere (except windows, as one cannot delete an executable which is being run). Unfortunately, this test still fails on linux for other reasons, but at least it gives us something to aim for. The original commit message was: This patch adds the scaffolding necessary for lldb to recognise symbol files generated by breakpad. These (textual) files contain just enough information to be able to produce a backtrace from a crash dump. This information includes: - UUID, architecture and name of the module - line tables - list of symbols - unwind information A minimal breakpad file could look like this: MODULE Linux x86_64 0000000024B5D199F0F766FFFFFF5DC30 a.out INFO CODE_ID 00000000B52499D1F0F766FFFFFF5DC3 FILE 0 /tmp/a.c FUNC 1010 10 0 _start 1010 4 4 0 1014 5 5 0 1019 5 6 0 101e 2 7 0 PUBLIC 1010 0 _start STACK CFI INIT 1010 10 .cfa: $rsp 8 + .ra: .cfa -8 + ^ STACK CFI 1011 $rbp: .cfa -16 + ^ .cfa: $rsp 16 + STACK CFI 1014 .cfa: $rbp 16 + Even though this data would normally be considered "symbol" information, in the current lldb infrastructure it is assumed every SymbolFile object is backed by an ObjectFile instance. So, in order to better interoperate with the rest of the code (particularly symbol vendors). In this patch I just parse the breakpad header, which is enough to populate the UUID and architecture fields of the ObjectFile interface. The rough plan for followup patches is to expose the individual parts of the breakpad file as ObjectFile "sections", which can then be used by other parts of the codebase (SymbolFileBreakpad ?) to vend the necessary information.

Move ObjectFile initialization out of SystemInitializerCommon Summary: For lldb-server, it is sufficient to parse only the native object file format for its target OS (no other file can be loaded into a running process). This moves the object file initialization code into specific initializer classes: lldb-test and liblldb get all object files; lldb-server gets only one of them. For this to work, I've needed to create a special SystemInitializer for use in lldb-server, instead of it calling directly into the common one. This reduces the size of lldb-server by about 2%, which is not earth-shattering, but it's an easy win, and it helps.

Initialization: remove ObjectContainer from Common This restructures the initialization path to move the ObjectContainer initialization into the *full* initialization path. This is not needed for the lldb-server initialization path. This helps strip off ~1MiB from the binary. llvm-svn: 359810

Rework LLDB system initialization. In an effort to reduce binary size for components not wishing to link against all of LLDB, as well as a parallel effort to reduce link dependencies on Python, this patch splits out the notion of LLDB initialization into "full" and "common" initialization. All code related to initializing the full LLDB suite lives directly in API now. Previously it was only referenced from API, but because it was defined in lldbCore, it would get implicitly linked against by everything including lldb-server, causing a considerable increase in binary size. By moving this to the API layer, it also creates a better layering for the ongoing effort to make the embedded interpreter replacable with one from a different language (or even be completely removeable). One semantic change necessary to get this all working was to remove the notion of a shared debugger refcount. The debugger is either initialized or uninitialized now, and calling Initialize() multiple times will simply have no effect, while the first Terminate() will now shut it down no matter how many times Initialize() was called. This behaves nicely with all of our supported usage patterns though, and allows us to fix a number of nasty hacks from before. Differential Revision: http://reviews.llvm.org/D8462 llvm-svn: 233758
