* [SystemZ] Fix choice of known-zero mask in insertion optimizationRichard Sandiford2013-12-03
| | | | | | | | | | | | | | | The backend converts 64-bit ORs into subreg moves if the upper 32 bits of one operand and the low 32 bits of the other are known to be zero. It then tries to peel away redundant ANDs from the upper 32 bits. Since AND masks are canonicalized to exclude known-zero bits, the test ORs the mask and the known-zero bits together before checking for redundancy. The problem was that it was using the wrong node when checking for known-zero bits, so could drop ANDs that were still needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196267 91177308-0d34-0410-b5e6-96231b3b80d8
* Enhance the fix of PR17631Michael Liao2013-12-03
| | | | | | | | | | | | | | | | - The fix to PR17631 fixes part of the cases where 'vzeroupper' should not be issued before 'call' insn. There're other cases where helper calls will be inserted not limited to epilog. These helper calls do not follow the standard calling convention and won't clobber any YMM registers. (So far, all call conventions will clobber any or part of YMM registers.) This patch enhances the previous fix to cover more cases 'vzerosupper' should not be inserted by checking if that function call won't clobber any YMM registers and skipping it if so. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196261 91177308-0d34-0410-b5e6-96231b3b80d8

* Don't set PrivateGlobalPrefix for NVPTX and R600.Rafael Espindola2013-12-03
| | | | | | These targets have special asm printers that don't use these. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196187 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-cov: Removed output to STDOUT/specified file.Yuchen Wu2013-12-03
| | | | | | | | | | | | Instead of asking the user to specify a single file to output coverage info and defaulting to STDOUT, llvm-cov now creates files for each source file with a naming system of: <source filename> + ".llcov". This is what gcov does and although it can clutter the working directory with numerous coverage files, it will be easier to hook the llvm-cov output to tools which operate on this assumption (such as lcov). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196184 91177308-0d34-0410-b5e6-96231b3b80d8

This is useful for debugging issues in the BlockFrequency implementation since one can easily visualize where probability mass and other errors occur in the propagation.

* llvm-cov: Store blocks rather than counts per line.Yuchen Wu2013-12-03
| | | | | | | | | Each line stores all the blocks that execute on that line, instead of only storing the line counts previously accumulated. This provides more information for each line, and will be useful for options in enabling block and branch information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196177 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-cov: Added edge struct for traversal in block.Yuchen Wu2013-12-03
| | | | | | | | | | | | | Added GCOVEdge which are simple structs owned by the GCOVFunction that stores the source and destination GCOVBlocks, as well as the counts. Changed GCOVBlocks so that it stores a vector of source GCOVEdges and a vector of destination GCOVEdges, rather than just the block number. Storing the block number was only useful for knowing the number of edges and for debug info. Using a struct is useful for traversing the edges, especially back edges which may be needed later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196175 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove PPCScoreboardHazardRecognizerHal Finkel2013-12-02
| | | | | | | | | | PPCScoreboardHazardRecognizer was a subclass of ScoreboardHazardRecognizer which did only one thing: filtered out nodes in EmitInstruction for which DAG->getInstrDesc(SU) returned NULL. This used to be the case for PPC pseudo instructions. As far as I can tell, this is no longer true, and so we can use ScoreboardHazardRecognizer directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196171 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info: drop debug info via upgrading path if version number does not match.Manman Ren2013-12-02
| | | | | | | | | | | | | | | Add a helper function getDebugInfoVersionFromModule to return the debug info version number for a module. "Verifier/module-flags-1.ll" checks for verification errors. It will seg fault when calling getDebugInfoVersionFromModule because of the incorrect format for module flags in the testing case. We make getModuleFlagsMetadata more robust by checking for error conditions. PR17982 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196158 91177308-0d34-0410-b5e6-96231b3b80d8

* XCore target: Make handling of large frames not dependent upon an FP.Robert Lytton2013-12-02
| | | | | | | | | | | | eliminateFrameIndex() has been reworked to handle both small & large frames with either a FP or SP. An additional Slot is required for Scavenging spills when not using FP for large frames. Reworked the handling of Register Scavenging. Whether we are using an FP or not, whether it is a large frame or not, and whether we are using a large code model or not are now independent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196091 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: add pseudo-instructions for lit-pool global materialisationTim Northover2013-12-02
| | | | | | | | | | | | These are used by MachO only at the moment, and (much like the existing MOVW/MOVT set) work around the fact that the labels used in the actual instructions often contain PC-dependent components, which means that repeatedly materialising the same global can't be CSEed. With small modifications, it could be adapted to how ELF finds the address of _GLOBAL_OFFSET_TABLE_, which would give similar benefits in PIC mode there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196090 91177308-0d34-0410-b5e6-96231b3b80d8
