c57905ef4d Mips assembler: Improve set register alias handling
This patch solves the problem of numeric register values not being accepted:

../set_alias.s:1:11: error: expected valid expression after comma
        .set    r4,$4
                    ^
The parsing of .set directive is changed and handling of symbols in code 
as well to enable this feature. 

The test example is added.

d50bcb2162 [SystemZ] Register compare-and-branch support
This patch adds support for the CRJ and CGRJ instructions.  Support for
the immediate forms will be a separate patch.

The architecture has a large number of comparison instructions.  I think
it's generally better to concentrate on using the "best" comparison
instruction first and foremost, then only use something like CRJ if
CR really was the natual choice of comparison instruction.  The patch
therefore opportunistically converts separate CR and BRC instructions
into a single CRJ while emitting instructions in ISelLowering.

bfe3212dd8 [SystemZ] Improve AsmParser handling of invalid instructions
Previously, an invalid instruction like:

	foo     %r1, %r0

would generate the rather odd error message:

....: error: unknown token in expression
	foo     %r1, %r0
		^

We now get the more informative:

....: error: invalid instruction
	foo     %r1, %r0
	^

The same would happen if an address were used where a register was expected.
We now get "invalid operand for instruction" instead.

f386961da3 [SystemZ] Improve AsmParser register parsing
The idea is to make sure that:

(1) "register expected" is restricted to cases where ParseRegister()
    is called and the token obviously isn't a register.

(2) "invalid register" is restricted to cases where a register-like "%..."
    sequence is found, but the "..." makes no sense.

(3) the generic "invalid operand for instruction" is used in cases where
    the wrong register type is used (GPR instead of FPR, etc.).

(4) the new "invalid register pair" is used if the register has the right type,
    but is not a valid register pair.

Testing of (1)-(3) is now restricted to regs-bad.s.  It uses a representative
instruction for each register class to make sure that only registers from
that class are accepted.

(4) is tested by both regs-bad.s (which checks all invalid register pairs)
and insn-bad.s (which tests one invalid pair for each instruction that
requires a pair).

While there, I changed "Number" to "Num" for consistency with the
operand class.

30a7a7c1fd VSTn instructions have a number of encoding constraints which are not implemented. I have added these using wrapper methods around the original custom decoder (incidentally - this is a huge poorly written method that should be cleaned up. I have left it as is since the changes would be much to hard to review).

bac932e9c3 Q registers are encoded in fields of the same length as D registers. As Q registers are half as many, the ARM reference manual mandates the least significant bit to be zeroed out. Failure to do so should result in an undefined instruction. With this change test/MC/Disassembler/ARM/invalid-VQADD-arm.txt is passing (removed XFAIL).

e152eac63e [PowerPC] Merge/rename PPC fixup types
Now that fixup_ppc_ha16 and fixup_ppc_lo16 are being treated exactly
the same everywhere, it no longer makes sense to have two fixup types.

This patch merges them both into a single type fixup_ppc_half16,
and renames fixup_ppc_lo16_ds to fixup_ppc_half16ds for consistency.
(The half16 and half16ds names are taken from the description of
relocation types in the PowerPC ABI.)

No change in code generation expected.

c299ad32c8 [PowerPC] Fix processing of ha16/lo16 fixups
The current PowerPC MC back end distinguishes between fixup_ppc_ha16
and fixup_ppc_lo16, which are determined by the instruction the fixup
applies to, and uses this distinction to decide whether a fixup ought
to resolve to the high or the low part of a symbol address.

This isn't quite correct, however.  It is valid -if unusual- assembler
to use, e.g.
  li 1, symbol@ha
or
  lis 1, symbol@l
Whether the high or the low part of the address is used depends solely
on the @ suffix, not on the instruction.

In addition, both
  li 1, symbol
and
  lis 1, symbol
are valid, assuming the symbol address fits into 16 bits; again, both
will then refer to the actual symbol value (so li will load the value
itself, while lis will load the value shifted by 16).


To fix this, two places need to be adapted.  If the fixup cannot be
resolved at assembler time, a relocation needs to be emitted via
PPCELFObjectWriter::getRelocType.  This routine already looks at
the VK_ type to determine the relocation.  The only problem is that
will reject any _LO modifier in a ha16 fixup and vice versa.  This
is simply incorrect; any of those modifiers ought to be accepted
for either fixup type.

If the fixup *can* be resolved at assembler time, adjustFixupValue
currently selects the high bits of the symbol value if the fixup
type is ha16.  Again, this is incorrect; see the above example
  lis 1, symbol

Now, in theory we'd have to respect a VK_ modifier here.  However,
in fact common code never even attempts to resolve symbol references
using any nontrivial VK_ modifier at assembler time; it will always
fall back to emitting a reloc and letting the linker handle it.

If this ever changes, presumably there'd have to be a target callback
to resolve VK_ modifiers.  We'd then have to handle @ha etc. there.

9122396a4d [PowerPC] Remove need for adjustFixupOffst hack
Now that applyFixup understands differently-sized fixups, we can define
fixup_ppc_lo16/fixup_ppc_lo16_ds/fixup_ppc_ha16 to properly be 2-byte
fixups, applied at an offset of 2 relative to the start of the 
instruction text.

This has the benefit that if we actually need to generate a real
relocation record, its address will come out correctly automatically,
without having to fiddle with the offset in adjustFixupOffset.

Tested on both 64-bit and 32-bit PowerPC, using external and
integrated assembler.

ed788b6283 Fix ARM FastISel tests, as a first step to enabling ARM FastISel
ARM FastISel is currently only enabled for iOS non-Thumb1, and I'm working on
enabling it for other targets. As a first step I've fixed some of the tests.
Changes to ARM FastISel tests:
- Different triples don't generate the same relocations (especially
  movw/movt versus constant pool loads). Use a regex to allow either.
- Mangling is different. Use a regex to allow either.
- The reserved registers are sometimes different, so registers get
  allocated in a different order. Capture the names only where this
  occurs.
- Add -verify-machineinstrs to some tests where it works. It doesn't
  work everywhere it should yet.
- Add -fast-isel-abort to many tests that didn't have it before.
- Split out the VarArg test from fast-isel-call.ll into its own
  test. This simplifies test setup because of --check-prefix.

b594c4c873 [SystemZ] Rework handling of constant PC-relative operands
The GNU assembler treats things like:

        brasl   %r14, 100

in the same way as:

        brasl   %r14, .+100

rather than as a branch to absolute address 100.  We implemented this in
LLVM by creating an immediate operand rather than the usual expr operand,
and by handling immediate operands specially in the code emitter.
This was undesirable for (at least) three reasons:

- the specialness of immediate operands was exposed to the backend MC code,
  rather than being limited to the assembler parser.

- in disassembly, an immediate operand really is an absolute address.
  (Note that this means reassembling printed disassembly can't recreate
  the original code.)

- it would interfere with any assembly manipulation that we might
  try in future.  E.g. operations like branch shortening can change
  the relative position of instructions, but any code that updates
  sym+offset addresses wouldn't update an immediate "100" operand
  in the same way as an explicit ".+100" operand.

This patch changes the implementation so that the assembler creates
a "." label for immediate PC-relative operands, so that the operand
to the MCInst is always the absolute address.  The patch also adds
some error checking of the offset.

f86e436fb9 The purpose of the patch is to fix the syntax of ARM mrc and mrc2 instructions when they are used to write to the APSR. In this case, the destination operand should be APSR_nzcv, and the encoding of the target should be 0b1111 (same as for PC). In pre-UAL syntax, this form used the PC register as a textual target. This is still allowed for backward compatibility.

ffc49cbea4 [ms-inline asm] Fix a crasher when we fail on a direct match.
The issue was that the MatchingInlineAsm and VariantID args to the
MatchInstructionImpl function weren't being set properly.  Specifically, when
parsing intel syntax, the parser thought it was parsing inline assembly in the
at&t dialect; that will never be the case.  

The crash was caused when the emitter tried to emit the instruction, but the
operands weren't set.  When parsing inline assembly we only set the opcode, not
the operands, which is used to lookup the instruction descriptor.
rdar://13854391 and PR15945

Also, this commit reverts r176036.  Now that we're correctly parsing the intel
syntax the pushad/popad don't match properly.  I've reimplemented that fix using
a MnemonicAlias.

5e220753ff [PowerPC] Add assembler parser
This adds assembler parser support to the PowerPC back end.

The parser will run for any powerpc-*-* and powerpc64-*-* triples,
but was tested only on 64-bit Linux.  The supported syntax is
intended to be compatible with the GNU assembler.

The parser does not yet support all PowerPC instructions, but
it does support anything that is generated by LLVM itself.
There is no support for testing restricted instruction sets yet,
i.e. the parser will always accept any instructions it knows,
no matter what feature flags are given.

Instruction operands will be checked for validity and errors
generated.  (Error handling in general could still be improved.)

The patch adds a number of test cases to verify instruction
and operand encodings.  The tests currently cover all instructions
from the following PowerPC ISA v2.06 Book I facilities:
Branch, Fixed-point, Floating-Point, and Vector. 
Note that a number of these instructions are not yet supported
by the back end; they are marked with FIXME.

A number of follow-on check-ins will add extra features.  When
they are all included, LLVM passes all tests (including bootstrap)
when using clang -cc1as as the system assembler.

62d77858be s tightens up the encoding description for ARM post-indexed ldr instructions. All instructions in this class have bit 4 cleared. It turns out that there is a test case for this, but it was marked XFAIL.

1ad3a410be ARM: Fix encoding of hint instruction for Thumb.
"hint" space for Thumb actually overlaps the encoding space of the CPS
instruction. In actuality, hints can be defined as CPS instructions where imod
and M bits are all nil.

Handle decoding of permitted nop-compatible hints (i.e. nop, yield, wfi, wfe,
sev) in DecodeT2CPSInstruction.

This commit adds a proper diagnostic message for Imm0_4 and updates all tests.

97265a4889 Mips assembler: .set reorder support
Mips have delayslots for certain instructions 
like jumps and branches. These are instructions 
that follow the branch or jump and are executed
before the jump or branch is completed.

Early Mips compilers could not cope with delayslots
and left them up to the assembler. The assembler would
fill the delayslots with the appropriate instruction,
usually just a nop to allow correct runtime behavior.

The default behavior for this is set with .set reorder.
To tell the assembler that you don't want it to mess with
the delayslot one used .set noreorder.

For backwards compatibility we need to support
.set reorder and have it be the default behavior in the 
assembler.

Our support for it is to insert a NOP directly after an
instruction with a delayslot when in .set reorder mode.
