Sean Silva aff5125f88 [yaml2obj][ELF] Don't explicitly set `Binding` with STB_* 
Instead, just have 3 sub-lists, one for each of
{STB_LOCAL,STB_GLOBAL,STB_WEAK}.

This allows us to be a lot more explicit w.r.t. the symbol ordering in
the object file, because if we allowed explicitly setting the STB_*
`Binding` key for the symbol, then we might have ended up having to
shuffle STB_LOCAL symbols to the front of the list, which is likely to
cause confusion and potential for error.

Also, this new approach is simpler ;)

Quentin Colombet 663150f637 ARM: Remove a (false) dependency on the memoryoperand's value as we do not use 
it at the moment.
This allows to form more paired loads even when stack coloring pass destroys the
memoryoperand's value.

Ulrich Weigand 68e2e1b32b [PowerPC] Clean up VK_PPC_TOC... names 
This is another minor cleanup; to bring enum names in line
with the corresponding @modifier names, this renames:

  VK_PPC_TOC -> VK_PPC_TOCBASE
  VK_PPC_TOC_ENTRY -> VK_PPC_TOC16

No code change intended.

Kevin Enderby 35fd79237f Update the X86 disassembler to use xacquire and xrelease when appropriate. 
This is a bit tricky as the xacquire and xrelease hints use the same bytes,
0xf2 and 0xf3, as the repne and rep prefixes.

Fortunately llvm has different llvm MCInst Opcode enums for rep/xrelease
and repne/xacquire. So to make this work a boolean was added the
InternalInstruction struct as part of the Prefix state which is set with the
added logic in readPrefixes() when decoding an instruction to determine
if these prefix bytes are to be disassembled as xacquire or xrelease.  Then
we let the matcher pick the normal prefix instructionID and we change the
Opcode after that when it is set into the MCInst being created.

Tom Stellard 6ec9e8043c R600: Expand v2i32 load/store instead of custom lowering 
The custom lowering causes llc to crash with a segfault.

Ideally, the custom lowering can be fixed, but this allows
programs which load/store v2i32 to work without crashing.

Sean Silva 05001b9f38 [yaml2obj][ELF] Add support for st_value and st_size. 
After this patch, the ELF file produced by
`yaml2obj-elf-symbol-basic.yaml`, when linked and executed on x86_64

executable that goes into an infinite loop!

Sean Silva c1c290b25e [yaml2obj][ELF] Add the section name -> section index map to State. 
One of the key things that the YAML format abstracts over is the use of
section numbers for referencing sections. Instead, textual section names
are used, which yaml2obj then translates into appropriate section
numbers. (Technically ELF doesn't care about section names (only section
numbers), but since this is a testing tool, readability counts).

This simplifies using section names as symbolic references in various
parts of the code. An upcoming commit will use this to allow symbols to
reference sections.

MIPS does not handle multiple relocations correctly, so two tests from the

Until the multiple relocations are fixed, XFAIL the MCJIT unittests for

Ulrich Weigand d412098f43 [MC] Support @ variants with directional labels 
The assembler parser common code supports recognizing symbol variants
using the @ modifer.  On PowerPC, it should also be possible to use
(some of) those modifiers with directional labels, like "1f@l".

This patch adds support for accepting symbol variants on directional
labels as well.

Ulrich Weigand 96e6578395 [PowerPC] Optimize @ha/@l constructs 
This patch adds support for having the assembler optimize fixups
to constructs like "symbol@ha" or "symbol@l" if "symbol" can be
resolved at assembler time.

This optimization is already present in the PPCMCExpr.cpp code
for handling PPC_HA16/PPC_LO16 target expressions.  However,
those target expression were used only on Darwin targets.

This patch changes target expression code so that they are
usable also with the GNU assembler (using the @ha / @l syntax
instead of the ha16() / lo16() syntax), and changes the
MCInst lowering code to generate those target expressions
where appropriate.

It also changes the asm parser to generate HA16/LO16 target
expressions when parsing assembler source that uses the
@ha / @l modifiers.  The effect is that now the above-
mentioned optimization automatically becomes available
for those situations too.

Ulrich Weigand 865a1efc13 [PowerPC] Support compare mnemonics with implied CR0 
Just like for branch mnemonics (where support was recently added), the
assembler is supposed to support extended mnemonics for the compare
instructions where no condition register is specified explicitly
(and CR0 is assumed implicitly).

This patch adds support for those extended compare mnemonics.
