Fix MLA defs to use register class GPRnopc.
Add encoding tests for multiply instructions.
(Alias for MUL/SMLAL/UMLAL added by r199026.)

Patch by Zhaoshi.

Switch a few instructions to use RI instead I so they don't require REX_W to be explicitly specified.

VEX_PREFIX_66 doesn't need to set the hasOpSize flag since VEX instructions don't use the size fields it controls.

Also add copy support for FPR16.
Also add a missing test case file belongs to commit r197361.

[AArch64 NEON] Custom lower conversion between vector integer and vector floating point if element bit-width doesn't match.

[mips][sched] Put AND, OR, XOR, MOVT_I, and MOVF_I in the same itinerary class as their non-microMIPS counterparts.

No functional change since both classes have the same InstrItinData definition.

llvm-svn: 199402

llvm-svn: 199397

No functional change since there are no InstrItinData's.

llvm-svn: 199396

This is necessary because the classes are shared between all implementations.

No functional change since the InstrItinData's have been duplicated.

This is necessary because the classes are shared between all schedulers.

Once this patch series is committed there will be an InstrItinClass for
each mnemonic with minimal grouping. This does increase the size of the
itinerary tables for each MIPS scheduler but we have a few options for dealing
with that later. These options include reducing the number of classes once
we see the best way to simplify them, or by extending tablegen to be able
to compress the table by eliminating duplicates entries, etc.

llvm-svn: 199391

This matches the itin class used by the non-microMIPS equivalents of these
instructions.

llvm-svn: 199389

[mips] IIImult should have an InstrItinData in the generic scheduler. Used the same one as for IIImul.

Affects:
  DMULT, DMULTu, MADD, MADD_MM, MADDU, MADDU_MM, MSUB, MSUB_MM, MSUBU,
  MSUBU_MM, MULT, MULTu

Does not affect MULT_MM, MULTu_MM since they are currently miscategorised
as IIImul.

Allow x86 mov instructions to/from memory with absolute address to be encoded and disassembled with a segment override prefix. Fixes PR16962.

llvm-svn: 199364

llvm-svn: 199357

Remove use of OpSize for populating VEX_PP field. A prefix encoding is now used instead. Simplify some other code. No functional changes intended.

than it needs to be by 1 bit but I need to finish some other things so 
that all the boundary cases will work in that situation. constpool.c
in test-suite will fail to assemble under our new internal test-suite sync
without this change.

This was never used for anything so we should just get rid of it.

MSVC on x64 requires that we create image relative symbol
references to refer to RTTI data. Seeing as how there is no way to
explicitly make reference to a given relocation type in LLVM IR, pattern
match expressions of the form &foo - &__ImageBase.

Add OpSize16 to the two byte forms of INC/DEC that we only use in 64-bit mode and a 64-bit only LEA. Even though we'll not be in 16-bit mode when we use them it makes their tables consistent with their 32-bit counterparts.

The GNU as behavior is a bit different and very strange. It will mark any
label that contains an instruction. We can implement that, but using the
type looks more natural since gas will not mark a function if a .word is
used to output the instructions!

llvm-svn: 199287

When expanding neon pseudo stores, it may miss the implicit uses of sub
regs, which may cause post RA scheduler reorder instructions that
breakes anti dependency.

For example:
  VST1d64QPseudo %R0<kill>, 16, %Q9_Q10, pred:14, pred:%noreg
  will be expanded to
    VST1d64Q %R0<kill>, 16, %D18, pred:14, pred:%noreg;

An instruction that defines %D20 may be scheduled before the store by
mistake.

This patches adds implicit uses for such case. For the example above, it
emits:
  VST1d64Q %R0<kill>, 8, %D18, pred:14, pred:%noreg, %Q9_Q10<imp-use>
