llvm-svn: 150902

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

llvm-svn: 150878

llvm-svn: 150795

Move old movl vector_shuffle patterns. Not needed anymore since vector_shuffles shouldn't reach isel.

llvm-svn: 150462

llvm-svn: 150365

llvm-svn: 150362

It caused 3 failures on pre-penryn and non-x86(generic) hosts.

llvm-svn: 150357

llvm-svn: 150328

llvm-svn: 150321

Remove some patterns for matching vector_shuffle instructions since vector_shuffles should be custom lowered before isel.

llvm-svn: 150299

Add target specific node for PMULUDQ. Change patterns to use it and custom lower intrinsics to it. Use it instead of intrinsic to handle 64-bit vector multiplies.

llvm-svn: 149807

Special handling was added for v4i32 -> v4i64 and v8i16 -> v8i32
extensions.

llvm-svn: 149600

Move some XOP patterns into instruction definition. Replae VPCMOV intrinsic patterns with custom lowering to a target specific nodes.

llvm-svn: 149216

Custom lower PSIGN and PSHUFB intrinsics to their corresponding target specific nodes so we can remove the isel patterns.

llvm-svn: 148933

Add comments near load pattern fragments indicating that all integer vector loads are promoted to v2i64 or v4i64 so that no one tries to reintroduce pattern fragments for other types.

llvm-svn: 148771

Remove pattern fragments for v32i8, v16i16, v8i32, v16i8, v8i16, and v4i32 loads. All integer vector loads are promoted to v2i64 or v4i64 so these pattern fragments can never match. Fix or remove patterns that used these fragments.

llvm-svn: 148672

llvm-svn: 148670

Merge PCMPEQB/PCMPEQW/PCMPEQD/PCMPEQQ and PCMPGTB/PCMPGTW/PCMPGTD/PCMPGTQ X86 ISD node types into only two node types. Simplifying opcode selection and pattern matching.

llvm-svn: 148667

Add target specific ISD node types for SSE/AVX vector shuffle instructions and change all the code that used to create intrinsic nodes to create the new nodes instead.

llvm-svn: 148664

llvm-svn: 148466

llvm-svn: 147394

llvm-svn: 146833

Remove some remants of the old palign pattern fragment that were still hanging around. Also remove a cast from inside getShuffleVPERM2X128Immediate and getShuffleVPERMILPImmediate since the only caller already had done the cast.

llvm-svn: 146344

llvm-svn: 145926

llvm-svn: 145485

Merge decoding of VPERMILPD and VPERMILPS shuffle masks. Merge X86ISD node type for VPERMILPD/PS. Add instruction selection support for VINSERTI128/VEXTRACTI128.

llvm-svn: 145483

Add X86 instruction selection for VPERM2I128 when AVX2 is enabled. Merge VPERMILPS/VPERMILPD detection since they are pretty similar.

llvm-svn: 145238

Merge 128-bit and 256-bit X86ISD node types for VPERMILPS and VPERMILPD. Simplify some shuffle lowering code since V1 can never be UNDEF due to canonalizing that occurs when shuffle nodes are created.

llvm-svn: 145153

Collapse X86ISD node types for PUNPCKH*, PUNPCKL*, UNPCKLP*, and UNPCKHP* to not be type specific. Now we just have integer high and low and floating point high and low. Pattern matching will choose the correct instruction based on the vector type.

llvm-svn: 145148

Remove 256-bit specific node types for UNPCKHPS/D and instead use the 128-bit versions and let the operand type disinquish. Also fix the load form of the v8i32 patterns for these to realize that the load would be promoted to v4i64.

llvm-svn: 145126

Remove AVX2 specific X86ISD node types for PUNPCKH/L and instead just reuse the 128-bit versions and let the vector type distinguish.

llvm-svn: 145125

llvm-svn: 145028

llvm-svn: 145026

Synthesize SSSE3/AVX 128-bit horizontal integer add/sub instructions from add/sub of appropriate shuffle vectors.

llvm-svn: 144989

llvm-svn: 144988

llvm-svn: 144987

llvm-svn: 143529

floating point add/sub of appropriate shuffle vectors.  Does not
synthesize the 256 bit AVX versions because they work differently.

llvm-svn: 140332

more strict about the alignment checking. This was found by inspection
and I don't have any testcases so far, although the llvm testsuite runs
without any problem.
