Rollup merge of #145415 - a4lg:riscv-implication-to-c, r=Amanieu
std_detect: RISC-V: implement implication to "C" Just like we implemented relatively complex rules to imply other extensions **from** "C" (and some others), this commit implements implication **to** the "C" extension from others, complying the following text in the ISA Manual (although there's no direct imply/depend references). > The C extension is the superset of the following extensions: > > - Zca > - Zcf if F is specified (RV32 only) > - Zcd if D is specified This is formally verified so that no other extension combinations (*not* in this implementation) can (currently) imply the "C" extension. Note: this is a `std_detect` change and not main target feature handling.
