This log is so big and tedious.
I prefer to have three separated commits, and for find_first_*, only two line
ERRORs are enough.
Thanks.

I checked these two files, and this patch looks good.
And, I'll put it into unicore32 repo.

For __muldi3, it is no longer used by gcc, so I think that's ok.
For __bswapsi2, maybe it's because I copied it from arm.

Sorry for replying so late.
I'd like to ack the patch after testing it.
Maybe before this weekend.
