Calling convention and extensions are separated, calling convention are specify the how argument passing and the register convention, so ILP32E *can* use with `-march=rv32efd`, but it can't pass or return floating point type in FPR. Just like we can `ILP32` for `-march=rv32ifd` and `LP64` with `-march=rv64ifd`, you may confused about the opposite combination like `ILP32D` with `-march=rv32i` and `LP64D` with `-march=rv64i` is not work, that's because it require pass or return floating point type in FPR, but FPR isn't existing in such ISA config.
