objective C or C++ methods when "self" or "this" were in scope, but had
invalid locations in a DWARF location list. The lack of a valid value caused
us to use an invalid type value and then we tried to import that invalid
value and we would crash.

would return instead of a less than helpful "name: '%s'" description.
Make sure that when we ask for the error from a ValueObject object we
first update the value if needed.
Cleaned up some SB functions to use internal functions and not re-call
through the public API when possible.

instructions if they are conditional. Also fixed issues where the PC wasn't
getting bit zero stripped for ARM targets when a stack frame was thumb. We
now properly call through the GetOpcodeLoadAddress() functions to make sure
the addresses are properly stripped for any targets that may decorate up
their addresses.
We now don't pass the SIGSTOP signals along. We can revisit this soon, but
currently this was interfering with debugging some older ARM targets that
don't have vCont support in the GDB server.

- ${*expr} now simply means to dereference expr before actually using it
- bitfields, array ranges and pointer ranges now work in a (hopefully) more natural and language-compliant way
a new class TypeHierarchyNavigator replicates the behavior of the FormatManager in going through type hierarchies
when one-lining summary strings, children's summaries can be used as well as values

a file or socket. We now make a getsockopt call to check if the fd is a socket.
Also, the previous logic in the GDB communication needs to watch for success
with an error so we can deal with EAGAIN and other normal "retry" error codes.

_only_ in the resulting stream, not in the error objects (lldb_private::Error).
lldb_private::Error objects should always just have an error string with no
terminating newline characters or periods.
Fixed an issue with GDB remote packet detection that could end up deadlocking
if a full packet wasn't received in one chunk. Also modified the packet
checking function to properly toss one or more bytes when it detects bad
data.
llvm-svn: 134357
- type names can now be regular expressions (exact matching is done first, and is faster)
- integral (and floating) types can be printed as bitfields, i.e. ${var[low-high]} will extract bits low thru high of the value and print them
- array subscripts are supported, both for arrays and for pointers. the syntax is ${*var[low-high]}, or ${*var[]} to print the whole array (the latter only works for statically sized arrays)
- summary is now printed by default when a summary string references a variable. if that variable's type has no summary, value is printed instead. to force value, you can use %V as a format specifier
- basic support for ObjectiveC:
- ObjectiveC inheritance chains are now walked through
- %@ can be specified as a summary format, to print the ObjectiveC runtime description for an object
- some bug fixes

"struct ", "class ", and "union " from the start of any type names that are
extracted from clang QualType objects. I had to fix test suite cases that
were expecting the struct/union/class prefix to be there.

implements three commands:
type summary add <format> <typename1> [<typename2> ...]
type summary delete <typename1> [<typename2> ...]
type summary list [<typename1> [<typename2>] ...]
type summary clear
This allows you to specify the default format that will be used to display
summaries for variables, shown when you use "frame variable" or "expression", or the SBValue classes.
Examples:
type summary add "x = ${var.x}" Point
type summary list
type summary add --one-liner SimpleType

level in the public API.
Also modified the ValueObject values to be able to display global variables
without having a valid running process. The globals will read themselves from
the object file section data if there is no process, and from the process if
there is one.
Also fixed an issue where modifications for dynamic types could cause child
values of ValueObjects to not show up if the value was unable to evaluate
itself (children of NULL pointer objects).
llvm-svn: 134102
Fixed crashes for SBValue fuzz calls.
And change 'bool SBType::IsPointerType(void)' to
'bool SBType::IsAPointerType(void)' to avoid name collision with the static 'bool SBType::IsPointerType(void *)'
function, which SWIG cannot handle.

changes that caused all SBValue objects to completely ignore the target
lock due to bad C++ scoping of the target Mutex::Locker variables.

two:
eOptionMarkPCSourceLine = (1u << 2), // Mark the source line that contains the current PC (mixed mode only)
eOptionMarkPCAddress = (1u << 3) // Mark the disassembly line the contains the PC
This allows mixed mode to show the line that contains the current PC, and it
allows us to mark the PC address in the disassembly if desired. Having these
be separate gives more control on the disassembly output. SBFrame::Disassemble()
doesn't enable any of these options.

inspection of namespaces in the expression parser.
ClangExpressionDeclMap hitherto reported that namespaces had
been completely imported, even though the namespaces are
returned empty. To deal with this situation, ClangASTSource
was recently extended with an API to complete incomplete type
definitions, and, for greater efficiency, to complete these
definitions partially, returning only those objects that have
a given name.
This commit supports these APIs on LLDB's side, and uses it
to provide information on types resident in namespaces.
Namespaces are now imported as they were -- that is to say,
empty -- but with minimal import mode on. This means that
Clang will come back and request their contents by name as
needed. We now respond with information on the contained
types; this will be followed soon by information on functions
and variables.

connected process connection.
Also added support for more kinds of continue packet when multiple threads
need to continue where some want to continue with signals.

the FormatManager class. Modified the format arguments in any commands to be
able to use a single character format, or a full format name, or a partial
format name if no full format names match.
Modified any code that was displaying formats to use the new FormatManager
calls so that our help text and errors never get out of date.
Modified the display of the "type format list" command to be a bit more
human readable by showing the format as a format string rather than the single
character format char.
llvm-svn: 133765
Added a fix for where you might have already displayed something with a given
type, then did a "type format add ...", then you display the type again. This
patch will figure out that the format changed and allow us to display the
type with the correct new format.
llvm-svn: 133743
This commit adds a new top level command named "type". Currently this command
implements three commands:
type format add <format> <typename1> [<typename2> ...]
type format delete <typename1> [<typename2> ...]
type format list [<typename1> [<typename2>] ...]
This allows you to specify the default format that will be used to display
types when you use "frame variable" or "expression", or the SBValue classes.
Examples:
// Format uint*_t as hex
type format add x uint16_t uint32_t uint64_t
// Format intptr_t as a pointer
type format add p intptr_t
The format characters are the same as "printf" for the most part with many
additions. These format character specifiers are also used in many other
commands ("frame variable" for one). The current list of format characters
include:
a - char buffer
b - binary
B - boolean
c - char
C - printable char
d - signed decimal
e - float
f - float
g - float
i - signed decimal
I - complex integer
o - octal
O - OSType
p - pointer
s - c-string
u - unsigned decimal
x - hex
X - complex float
y - bytes
Y - bytes with ASCII

- Respect DESTDIR.
- Use the realpath function on the path before prepending DESTDIR.
- Don't depend on liblldb.{so,dylib} being installed already.
- Don't put the DESTDIR into the _lldb.so symlink.
