The root of the problem was that findMainViewFileID(File, Function) could return some ID for any given file, even though that file was not the main file for that function. This patch ensures that the result of this function is conformed with the result of findMainViewFileID(Function). This commit reapplies r266436, which was reverted by r266458, with the .covmapping file serialized in v1 format. Differential Revision: http://reviews.llvm.org/D18787 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@266620 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
