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.

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.

Chris Lattner a3a0681083 Enhance llvm::SourceMgr to support diagnostic ranges, the same way clang does. Enhance
the X86 asmparser to produce ranges in the one case that was annoying me, for example:

test.s:10:15: error: invalid operand for instruction
movl 0(%rax), 0(%edx)
              ^~~~~~~

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

Kevin Enderby 5dcda64338 Adding back support for printing operands symbolically to ARM's new disassembler
using llvm's public 'C' disassembler API now including annotations.

Hooked this up to Darwin's otool(1) so it can again print things like branch
targets for example this:
 blx _puts
instead of this:
 blx #-36
and includes support for annotations for branches to symbol stubs like:
 bl	0x40 @ symbol stub for: _puts
and annotations for pc relative loads like this:
 ldr	r3, #8 @ literal pool for: Hello, world!
Also again can print the expression encoded in the Mach-O relocation entries for
things like this:
 movt r0, :upper16:((_foo-_bar)+1234)
