* [Coverage] Emit gap areas in braces-optional statements (PR35387)Vedant Kumar2017-11-291-8/+11
| | | | | | | | | | | | Emit a gap area starting after the r-paren location and ending at the start of the body for the braces-optional statements (for, for-each, while, etc). The count for the gap area equal to the body's count. This extends the fix in r317758. Fixes PR35387, rdar://35570345 Testing: stage2 coverage-enabled build of clang, check-clang llvm-svn: 319373
* [PGO] cc1 option name change for profile instrumentationRong Xu2016-02-041-1/+1
| | | | | | | | | | | | This patch changes cc1 option -fprofile-instr-generate to an enum option -fprofile-instrument={clang|none}. It also changes cc1 options -fprofile-instr-generate= to -fprofile-instrument-path=. The driver level option -fprofile-instr-generate and -fprofile-instr-generate= remain intact. This change will pave the way to integrate new PGO instrumentation in IR level. Review: http://reviews.llvm.org/D16730 llvm-svn: 259811

* InstrProf: Rewrite most of coverage mapping generation in a simpler wayJustin Bogner2015-02-181-4/+4
| | | | | | | | | | | | | | | | | | | | | | | The coverage mapping generation code previously generated a large number of redundant coverage regions and then tried to merge similar ones back together. This then relied on some awkward heuristics to prevent combining of regions that were importantly different but happened to have the same count. The end result was inefficient and hard to follow. Now, we more carefully create the regions we actually want. This makes it much easier to create regions at precise locations as well as making the basic approach quite a bit easier to follow. There's still a fair bit of complexity here dealing with included code and macro expansions, but that's pretty hard to avoid without significantly reducing the quality of data we provide. I had to modify quite a few tests where the source ranges became more precise or the old ranges seemed to be wrong anyways, and I've added quite a few new tests since a large number of constructs didn't seem to be tested before. llvm-svn: 229748

* Add tests for coverage mapping generation.Alex Lorenz2014-08-191-0/+37
| | | | | | | | | | This patch adds the tests for the coverage mapping generation. Most of the tests check the mapping regions produced by the generator, and one checks the llvm IR. Differential Revision: http://reviews.llvm.org/D4847 llvm-svn: 215995
* Revert "Add tests for coverage mapping generation."Justin Bogner2014-08-091-61/+0
| | | | | | | | | | | | | | | I reverted one of the added tests from r215261 in r215274, since it was failing on quite a few bots. It looks like this wasn't sufficient, as we're still getting failures on windows, like the following: http://bb.pgr.jp/builders/ninja-x64-msvc-RA-centos6/builds/5378 I'm reverting this entire commit so the bots aren't blocked on these failures. This reverts commit r215261. llvm-svn: 215278
