* Tweak a couple of -fprofile tests in clang/test to accept backslash in path.NAKAMURA Takumi2015-07-102-3/+3
| | | | llvm-svn: 241903

* Add support for fast-math flags to the FCmp instruction.James Molloy2015-07-108-54/+149
| | | | | | | | | | | | | | FCmp behaves a lot like a floating-point binary operator in many ways, and can benefit from fast-math information. Flags such as nsz and nnan can affect if this fcmp (in combination with a select) can be treated as a fminnum/fmaxnum operation. This adds backwards-compatible bitcode support, IR parsing and writing, LangRef changes and IRBuilder changes. I'll need to audit InstSimplify and InstCombine in a followup to find places where flags should be copied. llvm-svn: 241901
* Add missing builtins to the PPC back end for ABI compliance (vol. 3)Nemanja Ivanovic2015-07-102-0/+5
| | | | | | | | | This patch corresponds to review: http://reviews.llvm.org/D10973 Back end portion of the third round of additions to altivec.h. llvm-svn: 241900
* Reapply test for r241811 with a fix for msvc compat mode.Benjamin Kramer2015-07-101-0/+16
| | | | | | | Delayed template parsing interferes with code completion, just distable it for this test. This reverts r241811. llvm-svn: 241899
* Respect alignment when loading up a coerced function argumentUlrich Weigand2015-07-109-95/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | Code in CGCall.cpp that loads up function arguments that need to be coerced to a different type may in some cases ignore the fact that the source of the argument is not naturally aligned. This may cause incorrect code to be generated. In some places in CreateCoercedLoad, we already have setAlignment calls to address this, but I ran into one where it was missing, causing wrong code generation on SystemZ. However, in that location, we do not actually know what alignment of the source location we can rely on; the callers do not pass anything to this routine. This is already an issue in other places in CreateCoercedLoad; and the same problem exists for CreateCoercedStore. To avoid pessimising code, and to fix the FIXMEs already in place, this patch also adds an alignment argument to the CreateCoerced* routines and uses it instead of forcing an alignment of 1. The callers are changed to pass in the best information they have. This actually requires changes in a number of existing test cases since we now get better alignment in many places.

* Disable loop re-rotation for -Oz (patch by Andrey Turetsky)Alexey Bataev2015-07-102-2/+32
| | | | | | | After changes in rL231820 loop re-rotation is performed even in -Oz mode. Since loop rotation is disabled for -Oz, it seems loop re-rotation should be disabled too. Differential Revision: http://reviews.llvm.org/D10961 llvm-svn: 241897
* [llvm-stress] Enhance scalar type selection from command line.Pawel Bylica2015-07-101-39/+54
| | | | | | | | | | llvm-stress command line options like -generate-x86-fp80 has been replaced with one list-like option -types. E.g. llvm-stress -types=x86_fp80,i100,i256,half. Default types (i1, i8, i16, i32, i64, float, double) are always added at the beginning of that list. Reviewers: hfinkel Differential Revision: http://reviews.llvm.org/D10667 llvm-svn: 241896

* [InstCombine] Properly combine metadata when replacing a load with anotherBjorn Steinbrink2015-07-102-1/+49
| | | | | | | | Not doing this can lead to misoptimizations down the line, e.g. because of range metadata on the replacing load excluding values that are valid for the load that is being replaced. llvm-svn: 241886
* Remove test that tests referring to the current working directory. YouDaniel Jasper2015-07-101-5/+0
| | | | | | | | | cannot assume that the current working directory is writable in all test environments. I don't know a better way to write this test of hand, lets discuss. Possibly, a better option would be to put these together with other test testing the driver directly. llvm-svn: 241885
* [NVPTX] declare no vector registersJingyue Wu2015-07-103-0/+47
| | | | | | | | | | | | | | | | | Summary: Without this patch, LoopVectorizer in certain cases (see loop-vectorize.ll) produces code with complex control flow which hurts later optimizations. Since NVPTX doesn't have vector registers in LLVM's sense (NVPTXTTI::getRegisterBitWidth(true) == 32), we for now declare no vector registers to effectively disable loop vectorization.

A new -display-file-lists option use this to display lists of good files (no compile errors), problem files, and a combined list with problem files preceded by a '#'. The problem files list can be used in the module map generation assistant mode to exclude problem files. The combined files list can be used during module map development.

* [LAA] Hide NeedRTCheck logic completely inside canCheckPtrAtRT, NFCAdam Nemet2015-07-091-31/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently canCheckPtrAtRT returns two flags NeedRTCheck and CanDoRT. NeedRTCheck says whether we need checks and CanDoRT whether we can generate the checks. The idea is to encode three states with these: Need/Can: (1) false/dont-care: no checks are needed (2) true/false: we need checks but can't generate them (3) true/true: we need checks and we can generate them This is pretty unnecessary since the caller (analyzeLoop) is only interested in whether we can generate the checks if we actually need them (i.e. 1 or 3). So this change cleans up to return just that (CanDoRTIfNeeded) and pulls all the underlying logic into canCheckPtrAtRT. By doing all this, we simplify analyzeLoop which is the complex function in LAA. There is further room for improvement here by using RtCheck.Need directly rather than a new local variable NeedRTCheck but that's for a later patch. llvm-svn: 241866
* [WinEH] Give up on using CSRs across 32-bit invokes for nowReid Kleckner2015-07-093-25/+54
| | | | | | | | | | | The runtime does not restore CSRs when transferring control back to the function handling the exception. According to the experts on IRC, LLVM's register allocator has no way to model register clobbers that only happen on one edge of the CFG. For now, don't worry about trying to use the meager three CSRs available on 32-bit X86 and just say that such invokes preserve nothing. llvm-svn: 241865

* MIR Parser: Report an error when parsing machine function with an empty body.Alex Lorenz2015-07-098-0/+42
| | | | | | | | | | This commit adds a new error which is reported when the MIR Parser encounters a machine function without any machine basic blocks. The machine verifier expects that the machine functions have at least one MBB, and this error will prevent machine functions without MBBs from reaching the machine verifier and crashing with an assertion. llvm-svn: 241862
