kito-cheng added a comment. Another proposal for -mcpu and -mtune:
Decoupling the -mcpu and -mtune option, -mcpu only accept concrete CPU, and -mtune for micro-arch/pipeline model, they accept different option set. e.g. -mcpu=sifive-e24 # Imply -march=rv32imafc -mtune=sifive-2-series -mtune=sifive-2-series # no effect on arch -mtune=rocket # no effect on arch So -mcpu=rocket is invalid, since it's micro-arch/pipeline model only, and -mtune=sifive-e24 is invalid too, because it's CPU not a micro-arch.
