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.

LLDB (Terminal) User Interface
==============================
This directory contains the curses user interface for LLDB. To use it, ensure Python can find your lldb module. You may have to modify PYTHONPATH for that purpose:
$ export PYTHONPATH=/path/to/lldb/module
Then, run the lui.py. To load a core file:
$ ./lui.py --core core
To create a target from an executable:
$ ./lui.py /bin/echo "hello world"
To attach to a running process:
$ ./lui.py --attach <pid>
Known Issues
============
1. Resizing the terminal will most likely cause lui to crash.
2. Missing paging in command-window
3. Only minimal testing (on Ubuntu Linux x86_64)
Missing Features
================
- stdin/stdout/stderr windows
- memory window
- backtrace window
- threads window
- tab-completion
- syntax-highlighting (via pygments library)
- (local) variables window
- registers window
- disassembly window
- custom layout

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)
llvm-svn: 192239
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
