* [Coverage] Ensure that coverage mapping data has an expected alignment in ↵Igor Kudrin2016-05-181-0/+0
| | | | | | | | | | | | | 'covmapping' files. Coverage mapping data is organized in a sequence of blocks, each of which is expected to be aligned by 8 bytes. This feature is used when reading those blocks, see VersionedCovMapFuncRecordReader::readFunctionRecords(). If a misaligned covearge mapping data has more than one block, it causes llvm-cov to fail.

* Reapply "[Coverage] Prevent detection of false instantiations in case of ↵Igor Kudrin2016-04-181-0/+0
| | | | | | | | | | | | | | | | | | macro expansion." The root of the problem was that findMainViewFileID(File, Function) could return some ID for any given file, even though that file was not the main file for that function. This patch ensures that the result of this function is conformed with the result of findMainViewFileID(Function). This commit reapplies r266436, which was reverted by r266458, with the .covmapping file serialized in v1 format. Differential Revision: http://reviews.llvm.org/D18787 llvm-svn: 266620
