[llvm-dev] [proposal] change default ABI for special riscv arch

In the clang's riscv driver,
the default abi is fomulated according to arch if no explicit -mabi is specified.
Is it possible to set the default abi to ilp32f for -march=rv32imacf. For my exployer's chip, HW F is used while SW D is used. Each time I have to write "-march=rv32imacf -mabi=ilp32f“， can it be simplified to only "-march=imacf" ? Just adding a line is enough.
if (MArch.substr(4).contains_lower("f") && !MArch.substr(4).contains_lower("d"))
Can I submit a patch to fix it?
