* Use -fsanitize-recover instead of -mllvm -msan-keep-going.Evgeniy Stepanov2016-11-072-10/+13

* When the ASTImporter imports a source location, it avoids importing macroSean Callanan2016-11-076-2/+27
| | | | | | | | | | | | | | | | | expansions by calling getSpellingLoc(). That's great in most cases, but for macros defined in the '<built-in>' source file, the source file is invalid and does not import correctly, causing an assertion failure (the assertion is Invalid SLocOffset or bad function choice). A more reliable way to avoid this is to use getFileLoc(), which does not return built-in locations. This avoids the crash but still preserves valid source locations. I've added a testcase that covers the previously crashing scenario. https://reviews.llvm.org/D26054 llvm-svn: 286144

* Disallow StringRef assignment from temporary std::strings.Jordan Rose2016-11-071-0/+9
| | | | | | | | | | | | | | | | | | | | | Similar to r283798, this prevents accidentally referring to temporary storage that goes out of scope by the end of the statement: someStringRef = getStringByValue(); someStringRef = (Twine("-") + otherString).str(); Note that once again the constructor still has this problem: StringRef someStringRef = getStringByValue(); because once again we occasionally rely on this in calls: takesStringRef(getStringByValue()); takesStringRef(Twine("-") + otherString); Still, it's a step. llvm-svn: 286139
* Add some facilities to work with a git monorepo (experimental setup)Mehdi Amini2016-11-071-0/+278
| | | | | | | | | | | | | | | Add a new script in llvm/utils/git-svn/. When present in the $PATH, it enables a `git llvm` command. It is providing at this point only the ability to push from the git monorepo: `git llvm push`. It is intended to evolves with more features, for instance I plan on features like `git llvm show r284955` to help working with sequential revision numbers. The push feature is taken from Justin Lebar's script available here: https://github.com/jlebar/llvm-repo-tools/ Differential Revision: https://reviews.llvm.org/D26334 llvm-svn: 286138

| | | | | | | | | | | | | | | | | | | | | | | | Summary: Some changes are made to cmake, especially the addition of a new LLVM_ENABLE_PROJECTS option that makes the build system aware of the monorepo directory structure.

* Fix use-of-temporary with StringRef in code coverageJordan Rose2016-11-071-2/+7
| | | | | | | | | | | | | The fixed code is basically identical to the same loop below, which might indicate an opportunity for refactoring. I just wanted to fix the use-of-temporary issue. Caught by adding a similar check to StringRef as r283798 did for ArrayRef. I'll be upstreaming that soon. Reviewed by Vedant Kumar as https://reviews.llvm.org/D26317. llvm-svn: 286122

* [OpenMP] Enable ThreadSanitizer to check OpenMP programsJonas Hahnfeld2016-11-0712-10/+346
| | | | | | | | | | | | | | | | | | | | | | This patch allows ThreadSanitizer (Tsan) to verify OpenMP programs. It means that no false positive will be reported by Tsan when verifying an OpenMP programs. This patch introduces annotations within the OpenMP runtime module to provide information about thread synchronization to the Tsan runtime. In order to enable the Tsan support when building the runtime, you must enable the TSAN_SUPPORT option with the following environment variable: -DLIBOMP_TSAN_SUPPORT=TRUE The annotations will be enabled in the main shared library (same mechanism of OMPT).

* [Thumb1] Move padding earlier when synthesizing TBBs off of the PCJames Molloy2016-11-072-1/+9
| | | | | | | | | | When the base register (register pointing to the jump table) is the PC, we expect the jump table to directly follow the jump sequence with no intervening padding. If there is intervening padding, the calculated offsets will not be correct. One solution would be to account for any padding in the emitted LDRB instruction, but at the moment we don't support emitting MCExprs for the load offset. In the meantime, it's correct and only a slight amount worse to just move the padding up, from just before the jump table to just before the jump instruction sequence. We can do that by emitting code alignment before the jump sequence, as we know the number of instructions in the sequence is always 4. llvm-svn: 286107
