The order in which GCOV file info is printed depends on the string hash function. This makes some GCOV tests brittle, because the tests must be updated whenever the hash function changes. Sort the filenames before printing out the file info to solve the problem. This should be relatively cheap. Differential Revision: https://reviews.llvm.org/D32512 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@301371 91177308-0d34-0410-b5e6-96231b3b80d8
These inputs were pre-generated to allow for easier testing of llvm-cov.
The files used to test the gcov compatible code coverage tool were generated
using the following method:
test.gcno and test.gcda were create by running clang:
clang++ -g -ftest-coverage -fprofile-arcs test.cpp
test.cpp.gcov was created by running gcov 4.2.1:
gcov test.cpp
The 'covmapping' files that are used to test llvm-cov contain raw sections
with the coverage mapping data generated by the compiler and linker. They are
created by running clang and llvm-cov:
clang++ -fprofile-instr-generate -fcoverage-mapping -o test test.cpp
llvm-cov convert-for-testing -o test.covmapping test
The 'profdata' files were generated by running an instrumented version of the
program and merging the raw profile data using llvm-profdata.
./test
llvm-profdata merge -o test.profdata default.profraw
