* [MBP] Factor out the optimizations on branch conditions and unanalyzable ↵Haicheng Wu2016-05-241-44/+49
| | | | | | | | | | | | | | | | | | | | | branches. NFCI. The benefits of this patch are -- We call AnalyzeBranch() to optimize unanalyzable branches, but the result of AnalyzeBranch() is not used. Now the result is useful. -- Before the layout of all the MBBs is set, the result of AnalyzeBranch() is not correct and needs to be fixed before using it to optimize the branch conditions. Now this optimization is called after the layout, the code used to fix the result of AnalyzeBranch() is not needed. -- The branch condition of the last block is not optimized before. Now it is optimized. Differential Revision: http://reviews.llvm.org/D20177 llvm-svn: 270623

* DWARF: Omit DW_AT_APPLE attributes (except ObjC ones) when not targeting LLDBDavid Blaikie2016-05-244-13/+25
| | | | | | | | | | | | | | | These attributes aren't used by other debuggers (& may be confused with other DWARF extensions) so they just waste space (about 1.5% on .dwo file size on a random large program I tested). We could remove the ObjC property ones too, but I figured they were probably more necessary when trying to understand ObjC (I could be wrong though) & so any debugger interested in working with ObjC would use them, perhaps? (also, there are some legacy tests in Clang that test for them - making it one of those annoying cross-project commits and/or cleanup to refactor those tests) llvm-svn: 270613

* [llvm-pdbdump] Rework command line options.Zachary Turner2016-05-242-3/+29
| | | | | | | | | When dumping huge PDB files, too many of the options were grouped together so you would get neverending spew of output. This patch introduces more granular display options so you can only dump the fields you actually care about. llvm-svn: 270607

* [ThinLTO] Change ODR resolution and internalization to be index-basedTeresa Johnson2016-05-241-194/+272
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch changes the ODR resolution and internalization to be based on updates to the Index, which are consumed by the backend portion of the transformations. It will be followed by an NFC change to move these out of libLTO's ThinLTOCodeGenerator so that it can be used by other linkers (gold and lld) and by ThinLTO distributed backends. The global summary-based portions use callbacks so that the client can determine the prevailing copy and other information in a client-specific way. Eventually, with the API being developed in D20268, these may be modified to use information such as symbol resolutions, supplied by the clients to the API.

* Recommit r270070 ([llvm-mc] - Teach llvm-mc to generate compressed debug ↵George Rimar2016-05-242-39/+21
| | | | | | | | | | | | | | | | | | | sections in zlib style.) Now, after landing r270560, r270557, r270320 it is a proper time. Original commit message: [llvm-mc] - Teach llvm-mc to generate compressed debug sections in zlib style. Before this patch llvm-mc generated zlib-gnu styled sections. That means no SHF_COMPRESSED flag was set, magic 'zlib' signature was used in combination with full size field. Sections were renamed to "*.z*". This patch reimplements the compression style to zlib one as zlib-gnu looks to be depricated everywhere. Differential revision: http://reviews.llvm.org/D20331 llvm-svn: 270569
* [ValueTracking, InstSimplify] extend isKnownNonZero() to handle vector constantsSanjay Patel2016-05-241-1/+14
| | | | | | | | | | | | | Similar in spirit to D20497 : If all elements of a constant vector are known non-zero, then we can say that the whole vector is known non-zero. It seems like we could extend this to FP scalar/vector too, but isKnownNonZero() says it only works for integers and pointers for now.

Fix was: 1) Had to regenerate dwarfdump-test-zlib.elf-x86-64, dwarfdump-test-zlib-gnu.elf-x86-64 (because llvm-symbolizer-zlib.test uses that inputs for its purposes and failed). 2) Updated llvm-symbolizer-zlib.test (updated used call function address to match new files + added one more check for newly created dwarfdump-test-zlib-gnu.elf-x86-64 binary input). 3) Updated comment in dwarfdump-test-zlib.cc. Original commit message: [llvm-dwarfdump] - Teach dwarfdump to decompress debug sections in zlib style. Before this llvm-dwarfdump only recognized zlib-gnu compression style of headers, this patch adds support for zlib style.

| | | | | | | | | | | | | | Before r269750 we did the comparisons in this loop in signed ints so that it DTRT when MinCSFrameIndex was 0. This was changed because it's now possible for MinCSFrameIndex to be UINT_MAX, but that introduced a bug when we were comparing `>= 0` - this is tautological in unsigned. Rework the comparisons here to avoid issues with unsigned wrapping. No test.

The behavior change in r270106 was that we could no longer assume that each LF_FUNC_ID record got its own type index. This patch adds a map from DINode* to TypeIndex, so we can stop making that assumption. This change also emits padding bytes between type records similar to the way MSVC does. The size of the type record includes the padding bytes. llvm-svn: 270485
