This is implemented by means of a get_dynamic_setting(target, setting_name) function vended by the Python module, which can respond to arbitrary string names with dynamically constructed
settings objects (most likely, some of those that PythonDataObjects supports) for LLDB to parse
This needs to be hooked up to the debugger via some setting to allow users to specify which module will vend the information they want to supply

gdb-format a (as in p/a) would fail as it needed to set a byte size (unsurprisingly enough)
This should be acknowledged by the condition check and not cause a failure

Fixed Module::ResolveSymbolContextForAddress() to be able to also look in the SymbolVendor's SymbolFile's ObjectFile for a more meaningful symbol when a symbol lookup finds a synthetic symbol from the main object file. This will help lookups on MacOSX as the main executable might be stripped, but the dSYM file always has a full symbol table.

Added a way to set hardware breakpoints from the "breakpoint set" command with the new "--hardware" option. Hardware breakpoints are not a request, they currently are a requirement. So when breakpoints are specified as hardware breakpoints, they might fail to be set when they are able to be resolved and should be used sparingly. This is currently hooked up for GDB remote debugging.
Linux and FreeBSD should quickly enable this feature if possible, or return an error for any breakpoints that are hardware breakpoint sites in the "virtual Error Process::EnableBreakpointSite (BreakpointSite *bp_site);" function.

Just pass a Target* into ObjectFileELF::GetImageInfoAddress so that
it can do the extra dereference necessary on MIPS, instead of passing
a flag back to the caller.

MIPS's .dyanamic section is read-only. Instead of using DT_DEBUG for
the pointer to dyld information it uses a separate tag DT_MIPS_RLD_MAP
which points to storage in the read-write .rld_map section, which in
turn points to the dyld information.

Fixed an issue where environment variables that contained special characters '$' and '#' would hose up the GDB server packet. We now use the QEnvironmentHexEncoded packet that has existed for a long time when we need to. Also added code that will stop sending the QEnvironmentHexEncoded and QEnvironment packets if they aren't supported.

On at least FreeBSD and NetBSD there is an extra field in the dyld link
map struct. I've left an assert for other OSes (i.e., Linux/mips) until
it's determined if they do the same.

Based on the POSIX x86_64 register context. This is sufficient for opening
a mips64 (big endian) core file. Subsequent changes will connect the
disassembler, dynamic loader support, ABI, etc.

ObjectFile::CopyData is used to copy a block of target memory to the
caller's buffer (e.g. for "memory read"). This should be a straight
memcpy, and not byte-swapped if the target and host have different
endianness.
Add a new DataExtractor::CopyData() method that performs this straight
copy and use it in ObjectFile::CopyData().

- By default, the above function will wait for at least one event
- Set wait_always=false to make the function return immediately if the process is already stopped

Use 32-bit register enums without gaps on 64-bit hosts.
Don't show 64-bit registers when debugging 32-bit targets.
Add psuedo gpr registers (ax, ah, al, etc.)
Add mmx registers.
Fix TestRegisters.py to not read ymm15 register on 32-bit targets.
Fill out and move gcc/dwarf/gdb register enums to RegisterContext_x86.h

Constant ValueObjects should clear their description as well as their summary. Rationale being that both can depend on deeper-than-constified data
so both are subject to changes in "unpredictable" ways
To see this consider repeatedly po'ing a persistent variable of a type whose -description result changes at each invocation

Implement SBTarget::CreateValueFromAddress() with a behavior equivalent to SBValue::CreateValueFromAddress()
(but without the need to grab an SBValue first just as a starting point to make up another SBValue out of whole cloth)

Formats (as in "type format") are now included in categories
The only bit missing is caching formats along with synthetic children and summaries, which might be now desirable
llvm-svn: 192217
This radar extends the notion of one-liner summaries to automagically apply in a few interesting cases
More specifically, this checkin changes the printout of ValueObjects to print on one-line (as if type summary add -c had been applied) iff:
this ValueObject does not have a summary
its children have no synthetic children
its children are not a non-empty base class without a summary
its children do not have a summary that asks for children to show up
the aggregate length of all the names of all the children is <= 50 characters
you did not ask to see the types during a printout
your pointer depth is 0
This is meant to simplify the way LLDB shows data on screen for small structs and similarly compact data types (e.g. std::pair<int,int> anyone?)
Feedback is especially welcome on how the feature feels and corner cases where we should apply this printout and don't (or viceversa, we are applying it when we shouldn't be)

that all clients use them explicitly. This will hopefully
prevent any future confusion where things get cast to types
we don't expect.
