Is it possible to use gcc like compiler flags? (ex. -ffast-math)

Some solutions implemented on C & Zig uses compiler flags to achieve tangible perfromance boost when leveraging compiler flags for optimiations. gcc (-Ofast):

gcc -Ofast

gcc -Ofast

https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html >> Disregard strict standards compliance. -Ofast enables all -O3 optimizations. It also enables optimizations that are not valid for all standard-compliant programs. It turns on -ffast-math, -fallow-store-data-races and the Fortran-specific -fstack-arrays, unless -fmax-stack-var-size is specified, and -fno-protect-parens. It turns off -fsemantic-interposition. Or Zig

...one important optimization: @setFloatMode(.Optimized)
It has about the same effect as setting -ffast-math in the C version.
