Craig Topper ed59dd34fd Various x86 disassembler fixes. 
Add VEX_LIG to scalar FMA4 instructions.
Use VEX_LIG in some of the inheriting checks in disassembler table generator.
Make use of VEX_L_W, VEX_L_W_XS, VEX_L_W_XD contexts.
Don't let VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE inherit from their non-L forms unless VEX_LIG is set.
Let VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE inherit from all of their non-L or non-W cases.
Increase ranking on VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE so they get chosen over non-L/non-W forms.

Craig Topper 1b8c0750ee Mark all the _REV instructions as not having side effects. They aren't really emitted by the backend, but it reduces the number of instructions in the output files with unmodelled side effects to make auditing easier.

Craig Topper a73be890a1 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.

 2012-06-04 07:46:16 +00:00
Craig Topper fd53b80219 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
 2012-06-03 07:26:46 +00:00

llvm-svn: 157895
 2012-06-03 01:40:43 +00:00
Craig Topper badd755a0e Add neverHasSideEffects and mayLoad to FMA3 instructions.

 2012-06-03 00:30:49 +00:00
Craig Topper 00649d5111 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. 
llvm-svn: 157804
 2012-06-01 06:07:48 +00:00
Craig Topper df09da8355 Tidy up. Remove trailing spaces and fix the worst of the 80 column violations.

 2012-06-01 05:24:29 +00:00
Elena Demikhovsky 602f3a26d6 Added FMA3 Intel instructions. 
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.

 2011-12-30 05:20:36 +00:00
Craig Topper cd93de93fa 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.

Craig Topper 6c08930c5e 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
 2011-12-30 02:18:36 +00:00
Craig Topper 2ca79b9d4b 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. 
llvm-svn: 147360
