Jim Ingham ea3ac27029 The actual indirect symbol is not the one at the address of the Trie entry marked with the EXPORT_SYMBOL_FLAGS_STUB_AND_RESOLVER, it is given in the address in the “other” field in that entry.

Ed Maste c113ff8cba elf: Move elf note parsing to ObjectFileELF.cpp
Separate ELF note implementations were introduced for core files and
GNU build-id.  Move the more general one from elf-core to ObjectFileELF
and use it for build-id as well.

Colin Riley 6c97042044 Fix for PECOFF GetArchitecture
0 as CPU subtype never matches anything (at least, it doesn't match x86_64 windows binaries, of which there are correct arch definitions for). It should be created with LLDB_INVALID_CPUTYPE.

Greg Clayton 9b2349888f Added the ability to get the SDK path for a target using the platform plugins. If LLDB lives inside an Xcode.app bundle, it will select the SDK in the Xcode bundle, else it will use the currently selected Xcode.
Also added the DWARFDataExtractor classes to the Xcode project file.

Greg Clayton 9191db47da <rdar://problem/14496092>
Fixed an issue with reexported symbols on MacOSX by adding support for symbols re-exporting symbols. There is now a new symbol type eSymbolTypeReExported which contains a new name for the re-exported symbol and the new shared library. These symbols are only used when a symbol is re-exported as a symbol under a different name.

Modified the expression parser to be able to deal with finding the re-exported symbols and track down the actual symbol it refers to.

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.

Ed Maste 5480365b25 Simplify indirect rld_map for mips (rework r192408).
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.

Ed Maste 04a8bab047 Support mips shared object debug info
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.

Ashok Thirumurthi 35729bb1f8 Adds an option to resolve a symbol from an address that can be used
to build out the symbol table as addresses are used, and implements
the mechanism for ELF to add stripped symbols from eh_frame.

Uses this mechanism to allow disassembly for addresses corresponding
to stripped symbols for ELF, and provide hooks to implement this for
PE COFF.

Also removes eSymbolContextTailCall in favor of an option for
ResolveSymbolContextForAddress for consistency with the documentation
for eSymbolContextEverything.  Essentially, this is just an option for
interpreting the so_addr.

Jason Molenda 7e50d9135f Change ProcessMachCore to search for both a user-process dyld binary
and a mach kernel in all the pages of the core file.  If it finds
a user-process dyld binary, assume this is a user process that had
a copy of the mach kernel in memory when it crashed (e.g. lldb doing
kernel debugging) even though we found the kernel binary first.

Also, change the error messages about sections extending past the end
of the file to be warnings and make the messages sound less severe.
Most user process core files have one section that isn't included in
the file and there's no reason to worry people about that.

Charles Davis 237ad9741a Plugins/ObjectFile/PECOFF: Use enums from LLVM, and don't use Mach-O definitions.
Since I renamed most of the LLVM Mach-O enums in r189314, I had to go fix
LLDB to use the new names. While I was here, I decided that a COFF
plugin really shouldn't be using Mach-O enums.

Jason Molenda b000e4d758 When ObjectFileMachO::GetModuleSpecifications is getting the ArchSpec
out of a binary, if the Mach-O binary is MH_PRELOAD ("standalone"), don't
let the OS be set to "ios" or "macosx" - there will be no dynamic loader
used when debugging this process.

Jason Molenda 5894a73862 Follow-up to the checkin of r188532 -- make sure that
we've read the ObjectFile's Symtab before we change the
File addresses in the Sections.

Jason Molenda 20eb31b907 Add a new Section::SetFileAddress method to change a Section's file
address.

When loading a dSYM, and the file addresses of the dSYM Sections are
different than the executable binary Sections' file addresses, the
debug info won't be remapped to the actual load addresses correctly.
This only happens with binaries on the in-memory shared cache binaries
where their File addresses have been set to their actual load address
(outside an offset value) whereas the original executable and dSYM
have 0-based File addresses.

I think this patch will not be activated for other cases -- this is
the only case we know of where the dSYM and the executable's File
addresses differ -- but if this causes other problems we can restrict
it more carefully.

LLDB needs in memory module load level settings to control how much information is read from memory when loading in memory modules. This change adds a new setting:

(lldb) settings set target.memory-module-load-level [minimal|partial|complete]

minimal will load only sections (no symbols, or function bounds via function starts or EH frame)
partial will load sections + bounds
complete will load sections + bounds + symbols
