2012-12-24Use a std::string rather than a dynamically allocated char* buffer.Benjamin Kramer
This affords us to use std::string's allocation routines and use the destructor for the memory management. Switching to that also means that we can use operator==(const std::string&, const char *) to perform the string comparison rather than resorting to libc functionality (i.e. strcmp). Patch by Saleem Abdulrasool! Differential Revision: http://llvm-reviews.chandlerc.com/D230 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171042 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-24CostModel: We have API for checking the costs of known shuffles. This patch addsNadav Rotem
support for the insert-subvector and extract-subvector kinds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171027 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-24Some x86 instructions can load/store one of the operands to memory. On SSE, ↵Nadav Rotem
this memory needs to be aligned. When these instructions are encoded in VEX (on AVX) there is no such requirement. This changes the folding tables and removes the alignment restrictions from VEX-encoded instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171024 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-24Change the codegen Cost Model API for shuffeles. This patch removes the API ↵Nadav Rotem
for broadcast and adds a more general API that accepts an enum of known shuffles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171022 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-23CostModel: Change the default target-independent implementation for findingNadav Rotem
the cost of arithmetic functions. We now assume that the cost of arithmetic operations that are marked as Legal or Promote is low, but ops that are marked as custom are higher. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171002 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-22X86: Turn mul of <4 x i32> into pmuludq when no SSE4.1 is available.Benjamin Kramer
pmuludq is slow, but it turns out that all the unpacking and packing of the scalarized mul is even slower. 10% speedup on loop-vectorized paq8p. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170985 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-22X86: Emit vector sext as shuffle + sra if vpmovsx is not available.Benjamin Kramer
Also loosen the SSSE3 dependency a bit, expanded pshufb + psra is still better than scalarized loads. Fixes PR14590. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170984 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-21In some cases, due to scheduling constraints we copy the EFLAGS.Nadav Rotem
The only way to read the eflags is using push and pop. If we don't adjust the stack then we run over the first frame index. This is not something that we want to do, so we have to make sure that our machine function does not copy the flags. If it does then we have to emit the prolog that adjusts the stack. rdar://12896831 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170961 91177308-0d34-0410-b5e6-96231b3b80d8
