[PATCH 1/2] gcov: re-fix clang-11+ support

2021-04-07 Thread Nick Desaulniers
LLVM changed the expected function signature for llvm_gcda_emit_function() in the clang-11 release. Users of clang-11 or newer may have noticed their kernels producing invalid coverage information: $ llvm-cov gcov -a -c -u -f -b .gcda -- gcno=.gcno 1 : checksum mismatch, \ (, ) != (, ) 2
