Fangrui Song <i at maskray dot me> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |FIXED --- Comment #1 from Fangrui Song <i at maskray dot me> --- This has been implemented in https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=2c7cfc7b418564a2f1f0e7a5b38dec7013ba5e18 (2022-06). Sorry that I did not check the trunk GCC. https://gcc.gnu.org/onlinedocs/gcc/Instrumentation-Options.html says "The -fsanitize-undefined-trap-on-error option is deprecated equivalent of -fsanitize-trap=all." (as expected).
