* [Coverage] Add an API to retrive all instantiations of a function (NFC)Vedant Kumar2017-08-021-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | The CoverageMapping::getInstantiations() API retrieved all function records corresponding to functions with more than one instantiation (e.g template functions with multiple specializations). However, there was no simple way to determine *which* function a given record was an instantiation of. This was an oversight, since it's useful to aggregate coverage information over all instantiations of a function. llvm-cov works around this by building a mapping of source locations to instantiation sets, but this duplicates logic that libCoverage already has (see FunctionInstantiationSetCollector). This change adds a new API, CoverageMapping::getInstantiationGroups(), which returns a list of InstantiationGroups. A group contains records for each instantiation of some particular function, and also provides utilities to get the total execution count within the group, the source location of the common definition, etc. This lets removes some hacky logic in llvm-cov by reusing FunctionInstantiationSetCollector and makes the CoverageMapping API friendlier for other clients. llvm-svn: 309904
* [llvm-cov] Allow specifying distinct architectures for each loaded binaryVedant Kumar2017-08-011-3/+4
| | | | | | | | | | | The coverage tool needs to know which slice to look at when it's handed a universal binary. Some projects need to look at aggregate coverage reports for a variety of slices in different binaries: this patch adds support for these kinds of projects to llvm-cov. rdar://problem/33579007 llvm-svn: 309747
* [Coverage] Remove two overloads of CoverageMapping::load. NFC.Vedant Kumar2017-06-301-12/+0
| | | | | | | | | | These overloads are essentially dead, and pose a maintenance cost without adding any benefit. This is coming up now because I'd like to experiment with changing the way we store coverage mapping data, and would rather not have to fix up the old overloads while doing so. Testing: check-{llvm,profile}, build clang. llvm-svn: 306776

* [Coverage] PR33517: Check for failure to load func recordsVedant Kumar2017-06-201-0/+3
| | | | | | | | | | | | With PR33517, it became apparent that symbol table creation can fail when presented with malformed inputs. This patch makes that sort of error detectable, so llvm-cov etc. can fail more gracefully. Specifically, we now check that function records loaded from corrupted coverage mapping data are rejected, e.g when the recorded function name is garbage. Testing: check-{llvm,clang,profile}, some unit test updates. llvm-svn: 305767
* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787

| | | | | | | | Pass a `MemoryBuffer &` to BinaryCoverageReader::create() instead of a `std::unique_ptr<MemoryBuffer> &`. This makes it easier to reason about the ownership of the buffer at a glance. llvm-svn: 273326
