Hi All, I am using llvm-cov in gcov mode. The options, as given below, work when using llvm 3.5 but do not when using latest svn llvm/clang 3.7. I cannot find the correct alternatives to this set of options for llvm 3.7. I know I can use gnu gcov or use -fprofile-instr-generate but I am hoping you can tell me the correct options for 3.7 clang and llvm-cov gcov or has the llvm-cov/clang in gcov mode been deprecated ?
I have been trying the following: ******begin test.cpp******** int foo() { return 0; } int main() { foo(); } *****end test,cpp***** *****begin bash****** $ clang -g -O0 --coverage test.cpp -o test $ ./test $ llvm-cov gcov test.cpp $ Unexpected number of edges (in _Z3foov). $ Invalid .gcda File! $clang -g -O0 --coverage -Xclang -coverage-cfg-checksum -Xclang -coverage-no-function-names-in-data -Xclang -coverage-version='402*' test.cpp -o test $ ./test $ llvm-cov gcov test.cpp $ Unexpected end of memory buffer: 270637176. $ Invalid .gcno File! *****end bash****** Thanks in advance for your help, Pierre Gousseau SN Systems - Sony Computer Entertainment
