* CodeGen: rename Win64 ExceptionHandling to WinEHSaleem Abdulrasool2014-06-295-27/+26
| | | | | | | | | | This exception format is not specific to Windows x64. A similar approach is taken on nearly all architectures. Generalise the name to reflect reality. This will eventually be used for Windows on ARM data emission as well. Switch the enum and namespace into an enum class. llvm-svn: 212000
* MC: rename EmitWin64EH routinesSaleem Abdulrasool2014-06-299-103/+101
| | | | | | | | | | | | | | | Rename the routines to reflect the reality that they are more related to call frame information than to Win64 EH. Although EH is implemented in an intertwined manner by augmenting with an exception handler and an associated parameter, the majority of these routines emit information required to unwind the frames. This also helps identify that these routines are generic for most windows platforms (they apply equally to nearly all architectures except x86) although the encoding of the information is architecture dependent. Unwinding data is emitted via EmitWinCFI* and exception handling information via EmitWinEH*. llvm-svn: 211994

* [x86] Fix a bug in the v8i16 shuffling exposed by the new splat-likeChandler Carruth2014-06-282-4/+5
| | | | | | | | | | | lowering for v16i8. ASan and some bots caught this bug with existing test cases. Fixing it even fixed a miscompile with one of the test cases. I'm still a bit suspicious of this test case as I've not taken a proper amount of time to think about it, but the fix here is strict goodness. llvm-svn: 211976

* [x86] Add handling for splat-like widenings of v16i8 shuffles.Chandler Carruth2014-06-282-5/+169
| | | | | | | | | | | | | | | | These show up really frequently, not the least with actual splats. =] We lowered these quite badly before. The new code path tries to widen i8 shuffles to i16 shuffles in a splat-like way. There are still some inefficiencies in our i16 splat logic though, so we aren't really done here. Also, for certain patterns (bit of a gather-and-splat) we still generate pretty silly code, and I've left a fixme for addressing it. However, I'm not actually worried about this code pattern as much. The old shuffle lowering generates a 29 instruction monstrosity for it that should execute much more slowly. llvm-svn: 211974
* This file wasn't supposed to be checked inDavid Majnemer2014-06-281-156/+0
| | | | | | | | | This was generated while trying to debug a test, it shouldn't have been checked in. Thanks to Alexander Kornienko for spotting this. llvm-svn: 211973

| | | | | | | | | Make llvm-cov compatible with gcov for cases where multiple files are specified on the command line. That is, loop over each one and report coverage, and report errors on stderr only rather than via return code. llvm-svn: 211959

* [RuntimeDyld] Add a framework for testing relocation logic in RuntimeDyld.Lang Hames2014-06-279-6/+908
| | | | | | | | | | | | | | | | | | | | This patch adds a "-verify" mode to the llvm-rtdyld utility. In verify mode, llvm-rtdyld will test supplied expressions against the linked program images that it creates in memory. This scheme can be used to verify the correctness of the relocation logic applied by RuntimeDyld. The expressions to test will be read out of files passed via the -check option (there may be more than one of these). Expressions to check are extracted from lines of the form: # rtdyld-check: <expression> This system is designed to fit the llvm-lit regression test workflow. It is format and target agnostic, and supports verification of images linked for remote targets. The expression language is defined in llvm/include/llvm/RuntimeDyldChecker.h . Examples can be found in test/ExecutionEngine/RuntimeDyld. llvm-svn: 211956
* [x86] Fix another bug hit when bootstrapping with the new shuffleChandler Carruth2014-06-272-9/+5
| | | | | | | | | | | | | lowering. For maximum irony, I had already discovered this bug, diagnosed it, and left FIXMEs about it in the test cases. =[ I just failed to go back over those until after i had reduced a bootstrap miscompile down to a single TU, stared at the assembly for an hour, and figured out the bug. Again. Oh well. llvm-svn: 211955
