2016-08-31[Coverage] Suppress creating a code region if the same area is covered by an ↵Igor Kudrin1-1/+10
expansion region. In most cases these code regions are just redundant, but sometimes they could be assigned to the counter of the parent code region instead of the counter of the nested block. Differential Revision: https://reviews.llvm.org/D23987 llvm-svn: 280199
2016-08-29[Coverage] Prevent creating a redundant counter if a nested body ends with a ↵Igor Kudrin1-0/+12
macro. If there were several nested statements arranged in a way that all of them end up with the same macro, then the expansion of this macro was assigned with all the corresponding counters of these statements. As a result, the wrong counter value was shown for the macro in llvm-cov. This patch fixes the issue by preventing adding a counter for an expanded source range if it already has an assigned counter, which is expected to come from the most specific statement.

2016-02-04[PGO] cc1 option name change for profile instrumentationRong Xu1-1/+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.

2015-02-18InstrProf: Rewrite most of coverage mapping generation in a simpler wayJustin Bogner1-14/+31
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

2014-08-19Add tests for coverage mapping generation.Alex Lorenz1-0/+26
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
2014-08-09Revert "Add tests for coverage mapping generation."Justin Bogner1-42/+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
