The --coverage flag is a useful alias for -fprofile-arcs
-ftest-coverage where the latter makes gcc output the .gcno file.
While it makes sense to use -fprofile-arcs without a .gcno file (pgo,
maybe more), it never really makes sense to request -fpath-coverage or
-fcondition-coverage without also wanting the .gcno to interpret the
results.
gcc/ChangeLog:
* common.opt: ftest-coverage enabled by fpath-coverage or
fcondition-coverage
gcc/testsuite/ChangeLog:
* g++.dg/gcov/gcov-18.C: Remove --coverage.
* g++.dg/gcov/gcov-22.C: Likewise.
* gcc.misc-tests/gcov-19.c: Remove -ftest-coverage.
* gcc.misc-tests/gcov-29.c: Likewise.
