Bruno Cardoso Lopes 792e906bef Start the support for AVX instructions with 256-bit %ymm registers. A couple of
notes:
- The instructions are being added with dummy placeholder patterns using some 256
  specifiers, this is not meant to work now, but since there are some multiclasses
  generic enough to accept them,  when we go for codegen, the stuff will be already
  there.
- Add VEX encoding bits to support YMM
- Add MOVUPS and MOVAPS in the first round
- Use "Y" as suffix for those Instructions: MOVUPSYrr, ...
- All AVX instructions in X86InstrSSE.td will move soon to a new X86InstrAVX
  file.

Chris Lattner ac5881295c Implement the major chunk of PR7195: support for 'callw'
in the integrated assembler.  Still some discussion to be
done.

Nico Weber 337e8db712 Add support for the x86 instructions "pusha" and "popa".

Dale Johannesen 44f9dfc9cf Next round of tail call changes. Register used in a tail
call must not be callee-saved; following x86, add a new
regclass to represent this.  Also fixes a couple of bugs.
Still disabled by default; Thumb doesn't work yet.

Bob Wilson 6eae520de9 Add instruction encoding for the Neon VMOV immediate instruction. This changes
the machine instruction representation of the immediate value to be encoded
into an integer with similar fields as the actual VMOV instruction.  This makes
things easier for the disassembler, since it can just stuff the bits into the
immediate operand, but harder for the asm printer since it has to decode the
value to be printed.  Testcase for the encoding will follow later when MC has
more support for ARM.

Sean Callanan e7e1cf9fbd Eliminated the classification of control registers into %ecr_
and %rcr_, leaving just %cr_ which is what people expect.
Updated the disassembler to support this unified register set.
Added a testcase to verify that the registers continue to be
decoded correctly.

Evan Cheng 31cdcd46d6 Re-apply 103156 and 103157. 103156 didn't break anything. 10315 exposed a coalescer bug that's fixed by 103170.

Sean Callanan 85d70594f0 Fixes to edis that mark x86 call targets as
memory operands rather than immediate operands.

Benjamin Kramer a050255103 EDis: Don't include inttypes.h. We support compilers which don't provide it. It was unused anyways.

Sean Callanan 814e69b171 Fixed a nasty layering violation in the edis source
code.  It used to #include the enhanced disassembly
information for the targets it supported straight
out of lib/Target/{X86,ARM,...} but now it uses a
new interface provided by MCDisassembler, and (so
far) implemented by X86 and ARM.

Also removed hacky #define-controlled initialization
of targets in edis.  If clients only want edis to
initialize a limited set of targets, they can set
--enable-targets on the configure command line.

Sean Callanan 03549ee5af Added support for ARM disassembly to edis.
I also added a rule to the ARM target's Makefile to
build the ARM-specific instruction information table
for the enhanced disassembler.

I will add the test harness for all this stuff in
a separate commit.

Chris Lattner 918be520dc change Target.getInstructionsByEnumValue to return a reference
to a vector that CGT stores instead of synthesizing it on every 
call.

Sean Callanan 7b0c339510 Updated the enhanced disassembly library's TableGen
backend to not use exceptions at all except in cases
of actual error.

Sean Callanan e9959a5f1a Updated the TableGen emitter for the Enhanced
Disassembler to take advantage of the refactored
AsmWriterInst.h.  Note removed parser code.

Sean Callanan d4b19e12ed Fixed some indentation in the AsmWriterInst
implementation.  Also changed the constructor
so that it does not require a Record, making it
usable by the EDEmitter.

Sean Callanan e8f5e8c9f8 Quick fix to make the header file for the enhanced
disassembly information have a better comment (and
better guard macros).

Sean Callanan 82436d1666 Added a custom TableGen backend to support the
enhanced disassembler, and the necessary makefile
rules to build the table for X86.
