| | | | | | | | | (icmp eq (ashr C1, %V) -1) may have multiple answers if C1 is not a power of two and has the sign bit set. This fixes PR24873. llvm-svn: 248074

* AMDGPU: Add failing testcase for live interval constructionMatt Arsenault2015-09-191-0/+29
| | | | llvm-svn: 248067
* test events: added optional value type to extra event key/val pairsTodd Fiala2015-09-183-4/+11
| | | | | | | | | | | | | The test events had worker indexes coming across as strings. I want them to be ints. worker_index now comes across as an int in the dicationary. The optional type can be specified with: --event-add-entries key=val[:type][,key2=val2[:type2]...] The type piece may be 'int' at this time. That is all. Otherwise it will be a string. llvm-svn: 248066

* Split off the binary literal warning into a subgroup of C++14 warningsRichard Trieu2015-09-183-2/+8
| | | | | | | | | Binary literals predate C++14, but they are listed as a C++14 extension since this was the first time they were standardized in the language. Move the warning into a subgroup so it can be selectively disabled when checking for other C++14 features. llvm-svn: 248064
* COFF: Use parallel_sort in Writer::sortExceptionTable().Rui Ueyama2015-09-181-4/+6
| | | | | | | This patch saves 4 ms out of 5 ms. Very small improvement, but maybe better than nothing. llvm-svn: 248063
* CGDebugInfo: Make creating a skeleton CU in getOrCreateModuleRef optional.Adrian Prantl2015-09-182-16/+25
| | | | | | | | | We don't want a skeleton CU when generating debug info for the module itself. NFC. llvm-svn: 248062

* On Linux, if you can't actually locate the libc++ install, do not attempt to ↵Enrico Granata2015-09-181-4/+9
| | | | | | | | | use it The failure mode when one gets this wrong is quite gnarly to then walk oneself out of, and if you can't actually find the library, trying to build against it is fairly pointless anyway This + my previous skip_if_library_missing change should make running the libc++ tests on a Linux machine without it much more seamless llvm-svn: 248057

* Simplify the interface of PCHContainerGenerator and friendsAdrian Prantl2015-09-185-54/+31

* COFF: Parallelize Writer::writeSections().Rui Ueyama2015-09-181-2/+3
| | | | | | | | Self-hosting took 801 ms on my machine. Of which this function took 69 ms. Now it takes 37 ms. That is about 4% overall performance improvement. llvm-svn: 248052

* Analyzer: Fix a crasher in UbigraphVizIsmail Pazarbasi2015-09-182-2/+10
| | | | | | | | | | | | | | | Summary: Name `Out` refers to the parameter. It is moved into the member `Out` in ctor-init. Dereferencing null pointer will crash clang, if user passes '-analyzer-viz-egraph-ubigraph' argument.

* [elf2] Convert if/else cascade into a covered switch. NFC.Michael J. Spencer2015-09-181-8/+16

* Added support for resolving symbolic links to FileSpec.Sean Callanan2015-09-183-2/+34
| | | | | | | | | | | | | | | We use the symbolic link to resolver to find the target of the LLDB shlib symlink if there is a symlink. This allows us to find shlib-relative resources even when running under the testsuite, where _lldb.so is a symlink in the Python resource directory. Also changed a comment to be slightly more clear about what resolve_path in the constructor for FileSpec means, since if we were actually using realpath() this code wouldn't have been necessary. http://reviews.llvm.org/D12984 llvm-svn: 248048
* Fix Makefile build by adding LLVMSupport to liblldbKeno Fischer2015-09-181-0/+1
| | | | | | | `llvm-mi` now depends on the regex functionality available in LLVM's support library. llvm-svn: 248047
* Reduce indentation in the TargetInfo implementations and fix upEric Christopher2015-09-181-369/+362
| | | | | | a couple of macro builtin redefines. llvm-svn: 248046
* [IndVars] Widen more comparisons for non-negative induction varsSanjoy Das2015-09-182-3/+154
| | | | | | | | | | | | | | | | | | | | Summary: If an induction variable is provably non-negative, its sign extension is equal to its zero extension. This means narrow uses like icmp slt iNarrow %indvar, %rhs can be widened into icmp slt iWide zext(%indvar), sext(%rhs) Reviewers: atrick, mcrosier, hfinkel Subscribers: hfinkel, reames, llvm-commits Differential Revision: http://reviews.llvm.org/D12745 llvm-svn: 248045

* [CMake] Refactoring and cleaning up clang symlink generation.Chris Bieneman2015-09-183-72/+13
| | | | | | | | Generation of clang symlinks now uses add_clang_symlink macro which uses add_llvm_symlink. Also the list of symlinks to generate is configurable via CLANG_LINKS_TO_CREATE. This re-lands r248015, with fixes for clang symlinks to always be generated as part of the clang and install-clang targets. llvm-svn: 248043

* [CMake] Adding ALWAYS_GENERATE option to symlink utility functions.Chris Bieneman2015-09-181-20/+33
| | | | | | This implements the behavior required for clang symlinks which should be always generated. llvm-svn: 248039
* COFF: Parallelize ICF.Rui Ueyama2015-09-182-28/+54
| | | | | | | | | | | | | | | The LLD's ICF algorithm is highly parallelizable. This patch does that using parallel_for_each. ICF accounted for about one third of total execution time. Previously, it took 324 ms when self-hosting. Now it takes only 62 ms. Of course your mileage may vary. My machine is a beefy 24-core Xeon machine, so you may not see this much speedup. But this optimization should be effective even for 2-core machine, since I saw speedup (324 ms -> 189 ms) when setting parallelism parameter to 2. llvm-svn: 248038
* Debug Info: Use the full module name as a key when caching DIModules.Adrian Prantl2015-09-182-3/+3
| | | | | | | | | | | The signature may not have been computed at the time the module reference is generated (e.g.: in the future while emitting debug info for a clang module). Using the full module name is safe because each clang module may only have a single definition. NFC. llvm-svn: 248037
* Adds parallel work queue index to test events, stdout/stderr results support.Todd Fiala2015-09-184-47/+185

* clang-cl: Don't warn on /bigobj flagNico Weber2015-09-182-1/+2
| | | | | | | | | | LLVM r217812 made it so that clang-cl implicitly creates bigobj files when needed, independent of this flag. It looks like cl has this flag to produce obj flags compatible with MSVS 2003's linker by default, something we don't care about. Since clang-cl always has /bigobj behavior, don't warn that the flag is unused, just ignore it silently. llvm-svn: 248034
* Yet another try at fixing this at every bot.Rafael Espindola2015-09-181-2/+2

* Relax this test further to pass in other bots.Rafael Espindola2015-09-181-4/+2
| | | | | | | | | The problem this time was the /clang matching the InstalledDir line. Now we just use regular expressions which are more flexible, if a bit less readable, than CHECK+CHECK-SAME. llvm-svn: 248031
* Update edge weights properly when merging blocks in if-conversion.Cong Hou2015-09-183-6/+140
| | | | | | | | In if-conversion, there is a utility function MergeBlocks() that is used to merge blocks. However, when new edges are built in this function the edge weight is either not provided or not updated properly, leading to a modified CFG with incorrect edge weights. This patch corrects this issue. Differential Revision: http://reviews.llvm.org/D12513 llvm-svn: 248030
* Fix test to pass when the directory name has lld in it.Rafael Espindola2015-09-181-5/+4
| | | | | | | | | | | | | | | CHECK-LABEL assumes that there is only one occurrence of the match. The output looks like: clang version 3.8.0 (trunk 247999) .... /path/to/build/dir/bin/clang-3.8 .... If the path contains lld, the second CHECK-LABEL matches it and we fail since there is no -cc1as between clang and lld. llvm-svn: 248029
