2012-12-25Rename LLVMContext diagnostic handler types and functions.Bob Wilson
These are now generally used for all diagnostics from the backend, not just for inline assembly, so this drops the "InlineAsm" from the names. No functional change. (I've left aliases for the old names but only for long enough to let me switch over clang to use the new ones.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171047 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-24Quiet gcc's -Wparenthesis warning. No functionality change.Nick Lewycky

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
2012-12-24Add LLVMContext::emitWarning methods and use them. <rdar://problem/12867368>Bob Wilson
When the backend is used from clang, it should produce proper diagnostics instead of just printing messages to errs(). Other clients may also want to register their own error handlers with the LLVMContext, and the same handler should work for warnings in the same way as the existing emitError methods. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171041 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-24CostModel: We have API for checking the costs of known shuffles. This patch addsNadav Rotem

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

2012-12-24LoopVectorizer: Fix an endless loop in the code that looks for reductions.Nadav Rotem

2012-12-22Remove a special case that doesn't seem necessary any longer.Jakob Stoklund Olesen
Back when this exception was added, it was skipping a lot more code, but now it just looks like a premature optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170989 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

2012-12-21In 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
