* MC: rename EmitWin64EH routinesSaleem Abdulrasool2014-06-297-88/+86
| | | | | | | | | | | | | | | 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 Carruth2014-06-281-1/+1
| | | | | | | | | | | 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 Carruth2014-06-281-0/+80
| | | | | | | | | | | | | | | | 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

* [RuntimeDyld] Add a framework for testing relocation logic in RuntimeDyld.Lang Hames2014-06-273-2/+654
| | | | | | | | | | | | | | | | | | | | 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 Carruth2014-06-271-1/+1

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

* IR: Add COMDATs to the IRDavid Majnemer2014-06-2721-96/+818
| | | | | | | | | | | | | | | | This new IR facility allows us to represent the object-file semantic of a COMDAT group. COMDATs allow us to tie together sections and make the inclusion of one dependent on another. This is required to implement features like MS ABI VFTables and optimizing away certain kinds of initialization in C++. This functionality is only representable in COFF and ELF, Mach-O has no similar mechanism. Differential Revision: http://reviews.llvm.org/D4178 llvm-svn: 211920

* [PowerPC] Constrain base register in PPCRegisterInfo::resolveFrameIndexUlrich Weigand2014-06-271-0/+8
| | | | | | | | | | | | | | | | | | | | | | I've run into a bug where current LLVM at -O0 (with fast-isel) generated invalid code like: ld 0, 20936(1) # 8-byte Folded Reload stw 12, 10348(0) stw 12, 10344(0) The underlying vreg had been introduced as base register by the Local Stack Slot Allocation pass. That register was constrained to G8RC by PPCRegisterInfo::materializeFrameBaseRegister to match the ADDI instruction used to set it, but it was *not* constrained to G8RC_NOX0 to fit the *use* of the register in an address. That should have happened in PPCRegisterInfo::resolveFrameIndex. This patch adds an appropriate constrainRegClass call. Reviewed by Hal Finkel. llvm-svn: 211897
