commit r16-7178-g94fa0d52a233227f1f8da4c0b7ff4d079b9458e4 Author: Jørgen Kvalsvik <[email protected]> Date: Mon Nov 3 23:48:25 2025 +0100 gcc: -f*-coverage implies -ftest-coverage 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.
