test run permformance numbers say as to whether it helps.

This reverts commit 99345. It was breaking buildbots.

llvm-svn: 99352

just use an empty result list.

This is work in progress. So far, SSE execution domain tables are added to
X86InstrInfo, and a skeleton pass is enabled with -sse-domain-fix.

Converted some of the NEON vcvt instructions to this format.

Teach isSafeToClobberEFLAGS to ignore dbg_value's. We need a MachineBasicBlock::iterator that does this automatically?

These instructions are only needed for codegen, so I've removed all the
explicit encoding bits for now; they should be set in the same way as the for
VLDMD and VSTMD whenever we add encodings for VFP.  The use of addrmode5
requires that the instructions be custom-selected so that the number of
registers can be set in the AM5Opc value.

source operand for use by storeRegToStackSlot.

MC: Add TargetAsmBackend::MayNeedRelaxation, for checking whether a particular instruction + fixups might need relaxation.

MC: Add TargetAsmBackend::WriteNopData and use to eliminate some target dependencies in MCMachOStreamer and MCAssembler.

corresponding NEON instructions, instead of operation they are currently
used for.

MC/X86: Fix an MCOperand link, when we parsing shrld $1,%eax and friends; I believe this fixes the last memory leaks under test/MC.

Patch by John Tytgat!

llvm-svn: 99096

with changes to add a separate optional register update argument.  Change all
the NEON instructions with address register writeback to use it.

llvm-svn: 99095

address register writeback.

llvm-svn: 99094

rewrite the existing VST3 and VST4 instructions to use the same classes as
the others.

llvm-svn: 99093

writeback, and refactor the existing double-spaced VST2 instructions.
These are only for the disassembler since codegen doesn't use them, at
least for now.

llvm-svn: 99090

llvm-svn: 99083

address register writeback.

llvm-svn: 99082

llvm-svn: 99081

rewrite the existing VLD3 and VLD4 instructions to use the same classes as
the others.

llvm-svn: 99080

llvm-svn: 99078

load/stores with address register writeback, and use "odd" suffix to distinguish
instructions to access odd numbered registers (instead of "a" and "b").
No functional changes.
