Naming the RV32E ABI with -mabi

asb opened this issue 7 years ago · 3 comments

Should the RV32E ABI be explicitly targeted using -mabi=ilp32e? This would seem consistent with the other supported ABIs having unique -mabi strings. Of course for RV32E, no other ABI string is valid.

@palmer-dabbelt, @kito-cheng - thoughts? -mabi=ilp32e makes a lot of sense to me.

Yeah, sounds good idea, I'll take gcc and binutils part.

I agree that we need some way for -march=rv32i to target the E ABI. -march=rv32i -mabi=ilp32e seems good to me.
