Remove EscapeFilter. It's funcionality can be covered by correctly using ExtendedFilter and ExactFilter. No functional change.

That's what it actually means, and with 16-bit support it's going to be
a little more relevant since in a few corner cases we may actually want
to distinguish between 16-bit and 32-bit mode (for example the bare 'push'
aliases to pushw/pushl etc.)

Patch by David Woodhouse

llvm-svn: 197768

Added scalar compare VCMPSS, VCMPSD.
Implemented LowerSELECT for scalar FP operations.
I replaced FSETCCss, FSETCCsd with one node type FSETCCs.
Node extract_vector_elt(v16i1/v8i1, idx) returns an element of type i1.

added EVEX_KZ to tablegen

Allow pinsrw/pinsrb/pextrb/pextrw/movmskps/movmskpd/pmovmskb/extractps instructions to parse either GR32 or GR64 without resorting to duplicating instructions.

Remove unneeded MMX instruction definition by moving pattern to an equivalent instruction definition and removing the filtering from the disassembler table building.

llvm-svn: 192175

Remove some instructions that existed to provide aliases to the assembler. Can be done with InstAlias instead. Unfortunately, this was causing printer to use 'vmovq' or 'vmovd' based on what was parsed. To cleanup the inconsistencies convert all 'vmovd' with 64-bit registers to 'vmovq', but provide an alias so that 'vmovd' will still parse.

llvm-svn: 192171

Remove some instructions that seem to only exist to trick the filtering checks in the disassembler table creation. Just fix up the filter to let the real instruction through instead.

Remove use of sprintf added to X86 disassembler tablegen code. Send message with instruction name to errs() instead and use a generic message for the llvm_unreachable. Consistent with other places in this file.

llvm-svn: 187333

llvm-svn: 187325

Added 512-bit operands printing.
Added instruction formats for KNL instructions.

llvm-svn: 187324

For decoding, keep the current behavior of always decoding these as their REP
versions. In the future, this could be improved to recognize the cases where
these behave as XACQUIRE and XRELEASE and decode them as such.

As these two instructions in AVX extension are privileged instructions for
special purpose, it's only expected to be used in inlined assembly.

Fixed decode of existing 3dNow prefetchw instruction
Intel is scheduled to add a compatible prefetchw (same encoding) to future CPUs

I've tried to find main moudle headers where possible, but the TableGen
stuff may warrant someone else looking at it.

llvm-svn: 169251

- Add RTM code generation support throught 3 X86 intrinsics:
  xbegin()/xend() to start/end a transaction region, and xabort() to abort a
  tranaction region

llvm-svn: 167573

Remove code for setting the VEX L-bit as a function of operand size from the code emitters and the disassembler table builder. Fix a couple instructions that were still missing VEX_L.

llvm-svn: 164204

llvm-svn: 162999

Mark MOVZX32_NOREX as isCodeGenOnly and neverHasSideEffects. The isCodeGenOnly change allows special detection of _NOREX instructions to be removed from tablegen disassembler code.

llvm-svn: 160951

llvm-svn: 160950

Remove check for sub class of X86Inst from filter function since caller guaranteed it. Replace another sub class check with ShouldBeEmitted flag since it was factored in there already.

llvm-svn: 160949

llvm-svn: 160948

Remove check for f256mem from has256BitOperands as nothing depended on it and it isn't the only 256-bit memory type anyway.

is one more that MRM_DF which is 55.  Previously, it held value 45, the same
as MRM_D0.

llvm-svn: 160465

Make x86 asm parser to check for xmm vs ymm for index register in gather instructions. Also fix Intel syntax for gather instructions to use 'DWORD PTR' or 'QWORD PTR' to match gas.

llvm-svn: 160420

llvm-svn: 160110

Support the following intrinsics:
llvm.x86.avx2.gather.d.pd, llvm.x86.avx2.gather.q.pd
llvm.x86.avx2.gather.d.pd.256, llvm.x86.avx2.gather.q.pd.256
llvm.x86.avx2.gather.d.ps, llvm.x86.avx2.gather.q.ps
llvm.x86.avx2.gather.d.ps.256, llvm.x86.avx2.gather.q.ps.256

Modified Disassembler to handle VSIB addressing mode.
