--- Comment #25 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > At least from a user's perspective, that error is not Ok. It does not say > "-fdelayed-branch is needed," it says "target is not able..." Admittedly. > Also, it is important for debugging that code compiled with -O_ is also able > to compile with -O0. Maybe, but honoring -fno-delayed-branch is more important on the SPARC.
