Per the October 12, 2012 Proposal for annotated disassembly output sent out by
Jim Grosbach this set of changes implements this for X86 and arm.  The llvm-mc
tool now has a -mdis option to produced the marked up disassembly and a couple
of small example test cases have been added.

disassembler requires a MCSubtargetInfo and a
MCInstrInfo to exist in order to initialize the
instruction printer and disassembler; however,
although the printer and disassembler keep
references to these objects they do not own them.
Previously, the MCSubtargetInfo and MCInstrInfo
objects were just leaked.

I have extended LLVMDisasmContext to own these
objects and delete them when it is destroyed.

llvm-svn: 154192

Make MCInstrInfo available to the MCInstPrinter. This will be used to remove getInstructionName and the static data it contains since the same tables are already in MCInstrInfo.

llvm-svn: 153860

Used to allow context sensitive printing of super-register or sub-register
references.

to why this is needed.  This broke the darwin's otool(1) program.  This change
was made in r144385.

This CL delays reading of function bodies from initial parse until
materialization, allowing overlap of compilation with bitcode download.

llvm-svn: 149918

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.

llvm-svn: 144385

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)

llvm-svn: 141129

In the disassembler C API, be careful not to confuse the comment streamer that the disassembler outputs annotations on with the streamer that the InstPrinter will print them on.

llvm-svn: 140217

Don't attach annotations to MCInst's.  Instead, have the disassembler return, and the printer accept, an annotation string which can be passed through if the client cares about annotations.

llvm-svn: 139876

The the MC disassembler C API to print in verbose mode.  Perhaps there should be a parameter to request verbose mode?

llvm-svn: 139821

Refactor instprinter and mcdisassembler to take a SubtargetInfo. Add -mattr= handling to llvm-mc. Reviewed by Owen Anderson.

llvm-svn: 139237

Fix apparent build error caused by r138948 on certain versions of GCC with -Werror. Sorry for the inconvenience.

llvm-svn: 138973

Remove broken emacs mode major notation marking a C++ file as C.
No functionality change.

These are strictly utilities for registering targets and components.

llvm-svn: 138450

llvm-svn: 135974

InitializeX86MCInstrInfo, etc. are combined into InitializeX86TargetMC.

llvm-svn: 135812

There is still a bit more refactoring left to do in Targets. But we are now very
close to fixing all the layering issues in MC.

llvm-svn: 135611

TargetLoweringObjectFileImpl down to MCObjectFileInfo.

TargetAsmInfo is done to one last method. It's *almost* gone!

llvm-svn: 135569

(including compilation, assembly). Move relocation model Reloc::Model from
TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine.

llvm-svn: 135468

to MCRegisterInfo. Also initialize the mapping at construction time.

This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step
towards fixing the layering violation.

llvm-svn: 135424

Rename createAsmInfo to createMCAsmInfo and move registration code to MCTargetDesc to prepare for next round of changes.

be the first encoded as the first feature. It then uses the CPU name to look up
features / scheduling itineray even though clients know full well the CPU name
being used to query these properties.

The fix is to just have the clients explictly pass the CPU name!

disassembler API.  Hooked this up to the ARM target so such tools as Darwin's
otool(1) can now print things like branch targets for example this:
  blx _puts
instead of this:
  blx #-36

things like this:
  movt r0, :upper16:((_foo-_bar)+1234)

otool(1), this time with the needed fix for case sensitive file systems :) .
This is a work in progress as the interface for producing symbolic operands is
not done.  But a hacked prototype using information from the object file's
relocation entiries and replacing immediate operands with MCExpr's has been
shown to work with no changes to the instrucion printer.  These APIs will be
moved into a dynamic library at some point.
