Add explicit VEX_L tags to all 256-bit instructions. This will allow us to remove code from the code emitters that examined operands to set the L-bit.

Rename fma4 intrinsics to just fma since they are now used for both FMA4 and FMA3. Autoupgrade support coming in a separate commit.

llvm-svn: 157898

Use sse_load_f32/64 for scalar FMA3 intrinsic patterns instead of 128-bit loads to match instruction behavior.

llvm-svn: 157895

llvm-svn: 157894

Remove fadd(fmul) patterns for FMA3. This needs to be implemented by paying attention to FP_CONTRACT and matching @llvm.fma which is not available yet. This will allow us to enablle intrinsic use at least though.

I disabled FMA3 autodetection, since the result may differ from expected for some benchmarks.
I added tests for GodeGen and intrinsics.
I did not change llvm.fma.f32/64 - it may be done later.

Emacs-tag and some comment fix for all ARM, CellSPU, Hexagon, MBlaze, MSP430, PPC, PTX, Sparc, X86, XCore.

Separate the concept of having memory access in operand 4 from the concept of having the W bit set for XOP instructons. Removes ORing W-bits in the encoder and will similarly simplify the disassembler implementation.

Change FMA4 memory forms to use memopv* instead of alignedloadv*. No need to force alignment on these instructions. Add a couple testcases for memory forms.

llvm-svn: 147361

Fix load size for FMA4 SS/SD instructions. They need to use f32 and f64 size, but with the special handling to be compatible with the intrinsic expecting a vector. Similar handling is already used elsewhere.

remaining FMA4 instructions and intrinsics with tests.

llvm-svn: 145525

tablegen patterns for scalar FMA4 operations and intrinsic. Also
add tests for vfmaddsd.

Patch by Jan Sjodin

llvm-svn: 145133

Add complete assembler support for FMA3 instructions, with descriptions and encodings taken from the AVX manual
