* LoopVectorize: Enable vectorization of the fmuladd intrinsicHal Finkel2012-12-251-0/+1

* Expand PPC64 atomic load and storeHal Finkel2012-12-251-0/+2
| | | | | | | | Use of store or load with the atomic specifier on 64-bit types would cause instruction-selection failures. As with the 32-bit case, these can use the default expansion in terms of cmp-and-swap. llvm-svn: 171072
* [msan] Fix handling of vectors of pointers.Evgeniy Stepanov2012-12-251-2/+7
| | | | | | | VectorType::getInteger() can not be used with them, because pointer size depends on the target. llvm-svn: 171070
* [msan] Fix handling of select with vector condition.Evgeniy Stepanov2012-12-251-2/+11

* VCVTSS2SD requires a strict alignment. Thanks Elena.Nadav Rotem2012-12-251-2/+2

* Rename LLVMContext diagnostic handler types and functions.Bob Wilson2012-12-254-27/+25
| | | | | | | | | 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.) llvm-svn: 171047
* Quiet gcc's -Wparenthesis warning. No functionality change.Nick Lewycky2012-12-241-1/+1

* Use a std::string rather than a dynamically allocated char* buffer.Benjamin Kramer2012-12-242-21/+6
| | | | | | | | | | | | | 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 llvm-svn: 171042
* Add LLVMContext::emitWarning methods and use them. <rdar://problem/12867368>Bob Wilson2012-12-248-33/+72
| | | | | | | | | 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. llvm-svn: 171041
* CostModel: We have API for checking the costs of known shuffles. This patch addsNadav Rotem2012-12-241-1/+2
| | | | | | support for the insert-subvector and extract-subvector kinds. llvm-svn: 171027
* Added 6 more value types: v32i1, v64i1, v32i16, v32i8, v64i8, v8f64Elena Demikhovsky2012-12-241-0/+12

* Some x86 instructions can load/store one of the operands to memory. On SSE, ↵Nadav Rotem2012-12-241-260/+260
| | | | | | | | | 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. llvm-svn: 171024

* Change the codegen Cost Model API for shuffeles. This patch removes the API ↵Nadav Rotem2012-12-241-1/+2

* LoopVectorizer: Fix an endless loop in the code that looks for reductions.Nadav Rotem2012-12-241-7/+8
| | | | | | | | The bug was in the code that detects PHIs in if-then-else block sequence. PR14701. llvm-svn: 171008
* CostModel: Change the default target-independent implementation for findingNadav Rotem2012-12-231-3/+13
| | | | | | | | 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. llvm-svn: 171002

* Remove a special case that doesn't seem necessary any longer.Jakob Stoklund Olesen2012-12-221-13/+2
| | | | | | | Back when this exception was added, it was skipping a lot more code, but now it just looks like a premature optimization. llvm-svn: 170989
* Use getNumOperands() instead of Operands.size().Jakob Stoklund Olesen2012-12-221-11/+11
| | | | | | | The representation of the Operands array is going to change soon so it can be allocated from a BumpPtrAllocator. llvm-svn: 170988
* X86: Turn mul of <4 x i32> into pmuludq when no SSE4.1 is available.Benjamin Kramer2012-12-221-5/+29
| | | | | | | 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. llvm-svn: 170985
* X86: Emit vector sext as shuffle + sra if vpmovsx is not available.Benjamin Kramer2012-12-221-8/+39
| | | | | | | Also loosen the SSSE3 dependency a bit, expanded pshufb + psra is still better than scalarized loads. Fixes PR14590. llvm-svn: 170984

* In some cases, due to scheduling constraints we copy the EFLAGS.Nadav Rotem2012-12-212-1/+21
| | | | | | | | | | | | 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 llvm-svn: 170961
