according to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100839 the real compiler flag enabling this bullshit isn't -fexpensive-optimizations but -ffp-contract=fast which for some(*) reason is default in optimized builds. I think it's best to disabled that optimization globally in case it also breaks other code (I really don't want to spend several days to hunt such an idiot bug again). I really doubt it makes any measurable performance difference. As https://twitter.com/stephentyrone/status/1399424911328874499 says that clang might also enable this in the future (though to =on instead of =fast which should be a bit saner but would still break our code), just set this option for all GCC-ish compilers incl. clang. (*) the reason of course is that GCC developers don't develop GCC for their users but to win idiotic SPEC benchmarks |
