If we have multiple coverage counts for the same segment, we need to add them up rather than arbitrarily choosing one. This fixes that and adds a test with template instantiations to exercise it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218432 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
