That sounds good to me as well - I'll update this PR with that change instead. |
Since 4feae05, most of the handling of warning options was rewritten to add such options based on hardcoded knowledge about what compilers support which options, and since which versions. This avoids a number of configure time checks, speeding up the cmake configuration. This avoids erroneously adding this option with GCC, which doesn't really support it. If testing for a warning option like -Wno-<foo> with GCC, GCC won't print any diagnostic at all, leading to the options being accepted incorrectly. However later, if compiling a file that actually prints another warning, GCC will also print warnings about these -Wno-<foo> options being unrecognized. This avoids extra warning spam like this, for every source file that does produce warnings with GCC: At global scope: cc1plus: note: unrecognized command-line option ‘-Wno-pass-failed’ may have been intended to silence earlier diagnostics
