Package: gcc-8 Version: 8-20180218-1 Severity: normal Hi,
In https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-no_005fsanitize-function-attribute gcc 8.0.1 claims to add a no_sanitize attribute which works the same as the clang one does. In practice however it doesn't, and it currently will only accept a single option. The example given above is: $ cat nosan.c void __attribute__ ((no_sanitize ("alignment", "object-size"))) f () { /* Do something. */; } int main(void) { return 0; } Which results in: $ gcc-8 nosan.c nosan.c:3:1: error: wrong number of arguments specified for ‘no_sanitize’ attribute f () { /* Do something. */; } ^ It would be really nice if that did work as documented, to avoid having to special case this in user code even more than we already do. Cheers, Ron
