We document both ways already. https://gcc.gnu.org/onlinedocs/gcc-12.2.0/gcc/Common-Function-Attributes.html#index-no_005fsanitize-function-attribute I would have said if we don't document both ways we should reject it but since it is documented already, maybe add to the documentation that clang does not accept the combined string way. ^ permalink raw reply [flat|nested] 2+ messages in thread
