Nadav Rotem 481e50efe0 X86: Prefer using VPSHUFD over VPERMIL because it has better throughput. 
llvm-svn: 169624

Craig Topper 216bcd522b Remove intrinsic specific instructions for (V)MOVQUmr with patterns pointing to the normal instructions.

Craig Topper ab47fe4e16 Implement proper handling for pcmpistri/pcmpestri intrinsics. Requires custom handling in DAGISelToDAG due to limitations in TableGen's implicit def handling. Fixes PR11305.

 2012-05-31 04:37:40 +00:00
Craig Topper 7daf897678 Remove 256-bit AVX non-temporal store intrinsics. Similar was previously done for 128-bit. 
llvm-svn: 156375
 2012-05-08 06:58:15 +00:00
Craig Topper d0271b27cb Fix 128-bit ptest intrinsics to take v2i64 instead of v4f32 since these are integer instructions.

Elena Demikhovsky 1adc1d53dd Fixed a bug in printing "cmp" pseudo ops.

I added the full testing for all possible pseudo-ops of cmp.
I extended X86AsmPrinter.cpp and X86IntelInstPrinter.cpp.

You'l also see lines alignments (unrelated to this fix) in X86IselLowering.cpp from my previous check-in.

Craig Topper b85e40f738 Remove pcmpgt/pcmpeq intrinsics as clang is not using them. 
llvm-svn: 149367
 2012-01-31 06:52:44 +00:00
Craig Topper b910984458 Allow CRC32 instructions to be selected when AVX is enabled. 
llvm-svn: 147411
 2012-01-01 19:51:58 +00:00
Craig Topper 1c064e0a89 Fix sfence, lfence, mfence, and clflush to be able to be selected when AVX is enabled. Fix monitor and mwait to require SSE3 or AVX, previously they worked even if SSE3 was disabled. Make prefetch instructions not set the execution domain since they don't use XMM registers. 
llvm-svn: 147409
 2012-01-01 19:40:22 +00:00
Craig Topper 6572e0f203 Fix a bunch of SSE/AVX patterns to use v2i64/v4i64 loads since all other integer vector loads are promoted to those. 
llvm-svn: 145927
 2011-12-06 09:04:59 +00:00
Craig Topper 12b72def4e Fix VINSERTF128/VEXTRACTF128 to be marked as FP instructions. Allow execution dependency fix pass to convert them to their integer equivalents when AVX2 is enabled. 
llvm-svn: 145376
 2011-11-29 05:37:58 +00:00
Chris Lattner 6aa6c0c3b7 remove some old autoupgrade logic 
llvm-svn: 145167
 2011-11-27 06:10:54 +00:00
Craig Topper 05baa85f58 Properly qualify AVX2 specific parts of execution dependency table. Also enable converting between 256-bit PS/PD operations when AVX1 is enabled. Fixes PR11370.

Jakob Stoklund Olesen a70e9417fb Kill and collapse outstanding DomainValues. 
DomainValues that are only used by "don't care" instructions are now
collapsed to the first possible execution domain after all basic blocks
have been processed.  This typically means the PS domain on x86.

For example, the vsel_i64 and vsel_double functions in sse2-blend.ll are
completely collapsed to the PS domain instead of containing a mix of
execution domains created by isel.

Craig Topper 0e7cbbabea Add new X86 AVX2 VBROADCAST instructions. 
llvm-svn: 143612

Craig Topper fec80c6ad2 Fix operand type for x86 pmadd_ub_sw intrinsic. 
llvm-svn: 143455

Craig Topper 9821e75e64 Fix operand type for int_x86_ssse3_phadd_sw_128 intrinsic 
llvm-svn: 143336
 2011-10-31 07:16:37 +00:00
Craig Topper 9cdb9ffa43 Fix return type for X86 mpsadbw instrinsic. The instruction takes in a vector of 8-bit integers, but produces a vector of 16-bit integers.

Bill Wendling 410ec4aad1 As Dan pointed out, movzbl, movsbl, and friends are nicer than their alias 
(movzx/movsx) because they give more information. Revert that part of the patch.

llvm-svn: 129498
 2011-04-14 01:46:37 +00:00
Bill Wendling 7e07d6fb69 Have the X86 back-end emit the alias instead of what's being aliased. In most 
cases, it's much nicer and more informative reading the alias.

Bill Wendling b902f1dd88 Reapply r129401 with patch for clang. 
llvm-svn: 129419
 2011-04-13 00:36:11 +00:00
Bill Wendling dbfde42468 Revert r129401 for now. Clang is using the old way of doing things. 
llvm-svn: 129403
 2011-04-12 22:59:27 +00:00
Bill Wendling 47c24875a1 Remove the unaligned load intrinsics in favor of using native unaligned loads. 
Now that we have a first-class way to represent unaligned loads, the unaligned
load intrinsics are superfluous.

First part of <rdar://problem/8460511>.

Chris Lattner 9edf3f50bf improve the setcc -> setcc_carry optimization to happen more 
consistently by moving it out of lowering into dag combine.

Add some missing patterns for matching away extended versions of setcc_c.

Dale Johannesen 9c3f6bf2bf Fix pastos in handling of AVX cvttsd2si, PR8491. 
Bruno, please review, but I'm pretty sure this is right.
Patch by Alex Mac!

Bruno Cardoso Lopes d6634a5b2e AVX doesn't support mm operations neither its instrinsics. 
The AVX versions of PALIGN and PABS* should only exist for
128-bit. Remove the unnecessary stuff.

 2010-08-11 17:39:23 +00:00
Bob Wilson 66161f5eb4 Revert new AVX intrinsic tests. They are breaking buildbots and Bruno is 
away from a computer now.
--- Reverse-merging r109881 into '.':
