Martin Liška <marxin at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hubicka at gcc dot gnu.org, | |nathan at gcc dot gnu.org --- Comment #8 from Martin Liška <marxin at gcc dot gnu.org> --- Ok so the functions like (execve, fork) are recognized as builtins in non-strict mode: https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html (Outside strict ISO C mode...) I would incline to provide either warning or to include these builtins with --coverage? Adding gcov maintainers.
