**The problem:** Bazel moves all `.gcov.json.gz` files to one directory. If in a test target, two source files have identical names, then the second `.gcov.json.gz` overwrites the first one. **The solution:** I added `gcno_path` to the move destination in order to distinguish multiple `.gcov.json.gz` with the same name. **Testing:** In the `test_cc_test_coverage_gcov` test case I added the `different/a.cc` source file, so currently we have the following source tree: ``` coverage_srcs/a.h coverage_srcs/a.cc coverage_srcs/b.h coverage_srcs/t.cc coverage_srcs/different/a.h coverage_srcs/different/a.cc ``` gcda and gcno files are created next to the source files. The final `gcov.json` files are placed in the corresponding paths: ``` $COVERAGE_DIR_VAR/coverage_srcs/*a.gcov.json.gz $COVERAGE_DIR_VAR/coverage_srcs/*t.gcov.json.gz $COVERAGE_DIR_VAR/coverage_srcs/different/*a.gcov.json.gz ``` Closes bazelbuild#16527.
