Rafael Espindola 7e0a793183 Handle reloc_signed_4byte in here. Not doing so was a regression from my 
previous commit. It is strange that we see it in 32 bits. We already
have a fixme about it.

Kevin Enderby e7739d484f The second part of support for generating dwarf for assembly source files. This 
generates the dwarf Compile Unit DIE and a dwarf subprogram DIE for each
non-temporary label.

The next part will be to get the clang driver to enable this when assembling
a .s file.  rdar://9275556

Rafael Espindola 0a7f336475 Handle the case of the magical _GLOBAL_OFFSET_TABLE_ showing up in a 
symbol difference. This matches gas behavior and fixes PR11513.

We still don't handle _GLOBAL_OFFSET_TABLE_ in data sections.

Jim Grosbach d6ae4ba002 Darwin assembler improved relocs when w/o subsections_via_symbols. 
When the file isn't being built with subsections-via-symbols, symbol
differences involving non-local symbols can be resolved more aggressively.
Needed for gas compatibility.

Jim Grosbach 25b63fa117 Move target-specific logic out of generic MCAssembler. 
Whether a fixup needs relaxation for the associated instruction is a
target-specific function, as the FIXME indicated. Create a hook for that
and use it.

Anton Korobeynikov 965e0c6de2 Emit the ctors in the proper order on ARM/EABI.

Michael J. Spencer de3a2118db MC/X86/COFF: Allow quotes in names when targeting MS/Windows, 
as MC is the only assembler we support.

This splits MS/Windows and GNU/Windows ASM infos into two seperate classes.
While there is currently only one difference, full MS C++ ABI support will
require many more.

   for example.

Evan Cheng ecb2908bf9 Sink codegen optimization level into MCCodeGenInfo along side relocation model 
and code model. This eliminates the need to pass OptLevel flag all over the
place and makes it possible for any codegen pass to use this information.

Bob Wilson 8d1c7dbdff Disable generation of compact unwind encodings. <rdar://problem/10441578> 
This still seems to be causing some failures.  It needs more testing before
it gets enabled again.

Daniel Dunbar 52823cc91c build: Attempt to rectify inconsistencies between CMake and LLVMBuild versions of explicit dependencies. 
- The hope is that we have a tool/test to verify these are accurate (and tight) soon.

Benjamin Kramer f554228d82 Clients are responsible for initializing the targets, remove it from the disassembler API. 
This will break users of the LLVMCreateDisasm API (not that I know of any). They have to call the 
LLVMInitializeAll* functions from llvm-c/Target.h themselves now. edis' C API in all its horribleness 
should be unaffected.

Eric Christopher 4996c70034 Add the support code to enable the dwarf accelerator tables. Upcoming patches 
to fix the types section (all types, not just global types), and testcases.

The code to do the final emission is disabled by default.

Benjamin Kramer c74798d5cf Add an option to pad an uleb128 to MCObjectWriter and remove the uleb128 encoding from the DWARF asm printer. 
As a side effect we now print dwarf ulebs with .ascii directives.

Kevin Enderby 82ed3be1fb Fixed a bug in the code to create a dwarf file and directory table entires when 
it is separating the directory part from the basename of the FileName.  Noticed 
that this:

  .file 1 "dir/foo"

when assembled got the two parts switched.  Using the Mac OS X dwarfdump tool
it can be seen easily:

% dwarfdump -a a.out
include_directories[  1] = 'foo'
                Dir  Mod Time   File Len   File Name
                ---- ---------- ---------- ---------------------------
file_names[  1]    1 0x00000000 0x00000000 dir
...

Which should be:
...
include_directories[  1] = 'dir'
                Dir  Mod Time   File Len   File Name
                ---- ---------- ---------- ---------------------------
file_names[  1]    1 0x00000000 0x00000000 foo

Kevin Enderby 6469fc275a First part of support for generating dwarf for assembly source files with the 
-g flag.  In this part we generate the .file for the source being assembled and
the .loc's for the assembled instructions.

The next part will be to generate the dwarf Compile Unit DIE and a dwarf
subprogram DIE for each non-temporary label.

Once the next part is done test cases will be added.  rdar://9275556

Nick Lewycky 40f8f2ff24 Add support for a new extension to the .file directive: 
.file filenumber "directory" "filename"

This removes one join+split of the directory+filename in MC internals. Because
bitcode files have independent fields for directory and filenames in debug info,
this patch may change the .o files written by existing .bc files.
