--- Comment #2 from qinzhao at gcc dot gnu.org --- (In reply to Andrew Pinski from comment #1) > -fno-strict-overflow maps directly to -fwrapv . > > If you want to use -fsanitize=signed-integer-overflow, you can just remove > both -fno-strict-overflow -fwrapv. -fwrapv is implied for code later on. is it possible to make -fsanitize=signed-integer-overflow work with -fwrapv?
