khchen added a comment. Herald added a subscriber: sameer.abuasal. @lenary You patch is very useful to look up the default march, thanks! But there is some issue if we set the default rv32 march as `rv32gc`. Because the default multilib does not include `rv32gc`/`lp32d` in riscv gnu toolchain, https://github.com/riscv/riscv-gcc/blob/ed3f6ec/gcc/config/riscv/t-elf-multilib#L19 so if user does not give the default march clang will not find the library and cause linking error. Do you think this is a clang's problem? or maybe this is just user's problem so they should config multilib to support `rv32gc/lip3d2d`?
