Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jason at gcc dot gnu.org --- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Ah, the C++ FE doesn't care about the nothrow attribute for the builtins, but about cfns.gperf only. The thing is, the C99 builtins are presumably conditional on the C++ version, for -std=c++11 and above should be nothrow and for -std=c++98 shouldn't be. So perhaps we need 2 or 3 separate gperf lists, one for C89, one for C99 and one for C11 functions? There are just very few C11 functions, but many C99 ones.
