92c1296361 [lldbsuite] Un-xfail tests on Windows that are now passing (pt.4)
This is a set of tests that were all marked as failing becuse of several different bugs. A couple of the bugs are now resolved as fixed since all the tests that were failing associated with the bug are now passing. It is possible that some of them are false positives, but there's a large number of unexpectedly passing tests on Windows, so I am doing a bulk un-xfail to get the buildbot to green.

e60bc53b46 [lldb] Add GetCurrentException APIs to SBThread, add frame recognizer for objc_exception_throw for Obj-C runtimes
This adds new APIs and a command to deal with exceptions (mostly Obj-C exceptions): SBThread and Thread get GetCurrentException API, which returns an SBValue/ValueObjectSP with the current exception for a thread. "Current" means an exception that is currently being thrown, caught or otherwise processed. In this patch, we only know about the exception when in objc_exception_throw, but subsequent patches will expand this (and add GetCurrentExceptionBacktrace, which will return an SBThread/ThreadSP containing a historical thread backtrace retrieved from the exception object. Currently unimplemented, subsequent patches will implement this).

Extracting the exception from objc_exception_throw is implemented by adding a frame recognizer.

This also add a new sub-command "thread exception", which prints the current exception.

eca07c592a Fix (and improve) the support for C99 variable length array types
Clang recently improved its DWARF support for C VLA types. The DWARF
now looks like this:

0x00000051:         DW_TAG_variable [4]
                     DW_AT_location( fbreg -32 )
                     DW_AT_name( "__vla_expr" )
                     DW_AT_type( {0x000000d3} ( long unsigned int ) )
                     DW_AT_artificial( true )
...
0x000000da:     DW_TAG_array_type [10] *
                 DW_AT_type( {0x000000cc} ( int ) )

0x000000df:         DW_TAG_subrange_type [11]
                     DW_AT_type( {0x000000e9} ( __ARRAY_SIZE_TYPE__ ) )
                     DW_AT_count( {0x00000051} )

Without this patch LLDB will naively interpret the DIE offset 0x51 as
the static size of the array, which is clearly wrong.  This patch
extends ValueObject::GetNumChildren to query the dynamic properties of
incomplete array types.

See the testcase for an example:

   4   int foo(int a) {
   5   	     int vla[a];
   6   	       for (int i = 0; i < a; ++i)
   7   	           vla[i] = i;
   8
-> 9            pause(); // break here
   10  		return vla[a-1];
   11   }

(lldb) fr v vla
(int []) vla = ([0] = 0, [1] = 1, [2] = 2, [3] = 3)
(lldb) quit

77198bc79b Remove Go debugger plugin
In January Davide sent an e-mail to the mailing list to suggest removing
unmaintained language plugins such as Go and Java. The plan was to have
some cool down period to allow users to speak up, however after that the
plugins were never actually removed.

This patch removes the Go debugger plugin.

The plugin can be added again in the future if it is mature enough both
in terms of testing and maintenance commitment.

bf2d112c15 [DWARFExpression] Read literars as unsigned values.
After landing r341457, we started seeing a failure on the swift-lldb
bots. The change was correct and pretty straightforward, a DW_OP_constu
was replaced with DW_OP_lit23, the value remaining identical.

  0x000000f4: DW_TAG_variable
		DW_AT_location    (0x00000000
		  [0x0000000100000a51,  0x0000000100000d47): DW_OP_lit23, DW_OP_stack_value)
		DW_AT_name        ("number")

However, this broke LLDB.

  (Int) number = <extracting data from value failed>

The value was read correctly, but apparently the value's type was different.
When reading a constu it was reading a uint64 (m_type = e_ulonglong) while for
the literal, it got a signed int (m_type = e_sint). This change makes sure we
read the value as an unsigned.

ae6ca2fc3f Allow IRInterpreter to deal with non-power-of-2 sized types to support some bitfield accesses.
Summary:
For some bitfield patterns (like the one added by this commit), Clang will
generate non-regular data types like i24 or i48. This patch follows a
pretty naive approach of just bumping the type size to the next power of 2.
DataExtractor know how to deal with weird sizes. The operations on Scalar
do not know how to deal with those types though, so we have to legalize the
size when creating a Scalar.

Summary:
1) When ReadRegister is called with a null register into on Windows, rather than crashing due to an access violation, simply return false. Not all registers and properties will be read or calculated correctly, but that is consistent with other platforms that also return false in that case
2) Update a couple of tests to reference pr37995 as their reason for failure since it is much more accurate. Support for floating point registers doesn't exist on Windows at all, rather than having issues.

733ad45b9f Android.rules: Use libc++ by default
libstdc++ will soon be dropped from the android NDK. This patch makes
sure we are prepared for that by using libc++ in tests by default (i.e.,
except for libstdc++ data formatter tests).

Only a couple of small tweaks were needed to make this work:
- Add the libc++ include paths to CXXFLAGS only. This was necessary to
  make the tests compile with -fmodules. The modules tests have been
  disabled, but this way, they will be ready for them if they are
  enabled.
- in one test I had to add an explicit std::string copy to make sure the
  copy constructor is there for the expression evaluator to find it.

std::printf and not ::printf).

This consolidates the tests where this was an issue to always include

necessary.

Apart from that, there is no functional change in the tests.

9cd4def1c6 Fix Module::FindTypes to return the correct number of matches.
In r331719, I changed Module::FindTypes not to limit the amount
of types returned by the Symbol provider, because we want all
possible matches to be able to filter them. In one code path,
the filtering was applied to the TypeList without changing the
number of types that gets returned. This is turn could cause
consumers to access beyond the end of the TypeList.

This patch fixes this case and also adds an assertion to
TypeList::GetTypeAtIndex to catch those obvious programming
mistakes.

Triggering the condition in which we performed the incorrect
access was not easy. It happened a lot in mixed Swift/ObjectiveC
code, but I was able to trigger it in pure Objective C++ although
in a contrieved way.

1739b7d076 Really test type lookup in TestCppTypeLookup.py
Summary:
... and fix one bug found this way. Currently, the test works not because
types are looked up correctly, but because by injecting local variables
we also materialize the types for Clang. If we disable the local variable
injection, then one check fails.

The reason of the failure is that FindTypes is run with max_matches==1
and this value is passed down to the symbol lookup functions. When the
search is performed only on the basename (like it's the case for an
entity defined in the root namespace), then the search will stop after
having found one match on the basename. But that match might be in a
namespace, we were really just looking up the basename in the accelerator
tables.

The solution is to not pass max_matches down, but to search without a
limit and let RemoveMismatchedTypes do its job afterwards. Note the
patch includes 2 hunks with the same change, but only the latter is
tested. I couldn't find a way to create a testcase for the other
branch of the if ('image lookup -t' allows me to get there, but it
only ever returns one type anyway).

ce05952943 Remove premature caching of the global variables list in CompileUnit.
This fixes a bug where

  (lldb) target var g_ptr

would populate the global variables list with exactly one entry
because SymbolFileDWARF::ParseVariables() was invoked with a list of
DIEs pre-filtered by name, such that a subsequent call to

  (lldb) fr var --show-globals

would only list that one variable, because CompileUnit::m_variables
was already initialized, fooling CompileUnit::GetVariableList().

CompileUnit::GetVariableList() grabs the *complete* list of variables
via (SymbolFileDWARF, ...)::ParseVariablesForContext and that still
calls CompileUnit::SetVariableList(variables) which acts as the
caching mechanism.
