This is a purely mechanical change explicitly casting any parameters for printf
style conversion. This cleans up the warnings emitted by gcc 4.8 on Linux.

This is a mechanical change addressing the various sign comparison warnings that
are identified by both clang and gcc. This helps cleanup some of the warning
spew that occurs during builds.

These changes were written by Greg Clayton, Jim Ingham, Jason Molenda.
It builds cleanly against TOT llvm with xcodebuild. I updated the
cmake files by visual inspection but did not try a build. I haven't
built these sources on any non-Mac platforms - I don't think this
patch adds any code that requires darwin, but please let me know if
I missed something.
In debugserver, MachProcess.cpp and MachTask.cpp were renamed to
MachProcess.mm and MachTask.mm as they picked up some new Objective-C
code needed to launch processes when running on iOS.

Add a GetFoundationVersion() to AppleObjCRuntime
This API is used to return and cache the major version of Foundation.framework, which is potentially a useful piece of data to key off of to enable or disable certain ObjC related behaviors (especially in data formatters)

This change makes significant improvements in the performance of
calculating a UUID within ObjectFileELF, and handles both running
processes and core files correctly. This does lazy evaluation of
UUID generation and caches the result when calculated.

(lldb) b puts
(lldb) expr -g -i0 -- (int)puts("hello")
First we will stop at the entry point of the expression before it runs, then we can step over a few times and hit the breakpoint in "puts", then we can continue and finishing stepping and fininsh the expression.
Main features:
- New ObjectFileJIT class that can be easily created for JIT functions
- debug info can now be enabled when parsing expressions
- source for any function that is run throught the JIT is now saved in LLDB process specific temp directory and cleaned up on exit
- "expr -g --" allows you to single step through your expression function with source code

ObjectFile::SetLoadAddress (Target &target,
lldb::addr_t value,
bool value_is_offset);
Now "value" is a slide if "value_is_offset" is true, and "value" is an image base address otherwise. All previous usage of this API was using slides.
Updated the ObjectFileELF and ObjectFileMachO SetLoadAddress methods to do the right thing.
Also updated the ObjectFileMachO::SetLoadAddress() function to not load __LINKEDIT when it isn't needed and to only load sections that belong to the executable object file.

Move some code that was in DynamicLoaderPOSIXDLYD into the
base class DynamicLoader. In the case of UpdateLoadedSections(),
the test to see whether a file is loadable (its address is zero)
is not generally applicable so that test is changed to a more
universally applicable check for the SHF_ALLOC flag on the section.
Also make it explicit that the reading of the module_id in
DynamicLoaderPOSIXDYLD::GetThreadLocalData() is using a hardcoded
size (of module_id) of 4, which might not be appropriate on
big-endian 64-bit systems, leaving a FIXME comment in place.

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.

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.

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.
llvm-svn: 193101
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.

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.

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.

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.

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.

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.

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.

Improve the documentation for the new target.memory-module-load-level setting, and also return an error when there is no nlist data when appropriate.
llvm-svn: 188317
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

- MachO files now correctly extract the UUID all the time
- More file size and offset verification done for universal mach-o files to watch for truncated files
- ObjectContainerBSDArchive now supports enumerating all objects in BSD archives (.a files)
- lldb_private::Module() can not be properly constructed using a ModuleSpec for a .o file in a .a file
- The BSD archive plug-in shares its cache for GetModuleSpecifications() and the create callback
- Improved printing for ModuleSpec objects
llvm-svn: 186211
- ObjectFile::GetSymtab() and ObjectFile::ClearSymtab() no longer takes any flags
- Module coordinates with the object files and contain a unified section list so that object file and symbol file can share sections when they need to, yet contain their own sections.
Other cleanups:
- Fixed Symbol::GetByteSize() to not have the symbol table compute the byte sizes on the fly
- Modified the ObjectFileMachO class to compute symbol sizes all at once efficiently
- Modified the Symtab class to store a file address lookup table for more efficient lookups
- Removed Section::Finalize() and SectionList::Finalize() as they did nothing
- Improved performance of the detection of symbol files that have debug maps by excluding stripped files and core files, debug files, object files and stubs
- Added the ability to tell if an ObjectFile has been stripped with ObjectFile::IsStripped() (used this for the above performance improvement)
