nsz at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |nsz at gcc dot gnu.org --- Comment #19 from nsz at gcc dot gnu.org --- that code was there for a reason.. now aarch64 fails because it cannot detect if the flags are supported or not. so if detection is turned off then on aarch64 "supports trapping" should always be false and likewise on any target that allows an implementation without trapping exceptions.
