* [x86] Fix a bug in the v8i16 shuffling exposed by the new splat-likeChandler Carruth2014-06-28
| | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211976 91177308-0d34-0410-b5e6-96231b3b80d8

* [x86] Add handling for splat-like widenings of v16i8 shuffles.Chandler Carruth2014-06-28
| | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211974 91177308-0d34-0410-b5e6-96231b3b80d8

* [RuntimeDyld] Add a framework for testing relocation logic in RuntimeDyld.Lang Hames2014-06-27
| | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211956 91177308-0d34-0410-b5e6-96231b3b80d8

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.

* IR: Add COMDATs to the IRDavid Majnemer2014-06-27
| | | | | | | | | | | | | | | | 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.

* cmake: Don't do anything for LLVM_ENABLE_ASSERTIONS=OFFReid Kleckner2014-06-27
| | | | | | | | | | | | | | | | | By default, CMake will set NDEBUG in Rel* builds and leave it off in debug builds, so we shouldn't need to do anything ourselves. Before this change, it was possible to a Debug build without assertions (aka Debug-Asserts in the autoconf system) by configuring with -DLLVM_ENABLE_ASSERTIONS=OFF, but this configuration isn't very useful. You can still get the same effect by explicitly adding -DNDEBUG to CFLAGS.
