Yuchen Wu cbbd20879e Fixed llvm-cov to count edges instead of blocks. ... This was a fundamental flaw in llvm-cov where it treated the values in the GCDA files as block counts instead of edge counts. This created incorrect line counts when branching was present. Instead, the edge counts should be summed to obtain the correct block count. The fix was tested using custom test files as well as single source files from the test-suite directory. The behaviour can be verified by reading the GCOV documentation that describes the GCDA spec ("ARC_COUNTS gives the counter values for those arcs that are instrumented") and the header description provided by GCOVProfiling.cpp ("instruments the code that runs to records (sic) the edges between blocks that run and emit a complementary "gcda" file on exit"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193299 91177308-0d34-0410-b5e6-96231b3b80d8		2013-10-24 01:51:04 +00:00

AutoUpgrade.cpp	Remove x86_sse42_crc32_64_8 intrinsic. It has no functional difference from x86_sse42_crc32_32_8 and was not mapped to a clang builtin. I'm not even sure why this form of the instruction is even called out explicitly in the docs. Also add AutoUpgrade support to convert it into the other intrinsic with appropriate trunc and zext.	2013-10-15 05:20:47 +00:00
