Hi Nathan > div (an isa-a insn), except for 5200, 5202, 5204 & 5206.

The user cannot select them directly (use > isaa,nohwdiv and isab,nousp respectively).

I think you really should produce objdump/readelf output similar to what you've proposed -- a user is going to have no clue what an "isa-a-minus" is. They should not need to refer to the documentation to find out, either! > This elf flag relabling is binary incompatible with the previous > version, but as that's only been committed for a couple of weeks, I > think that is ok. Agreed; more importantly, there have been no official binutils releases. > built & tested on m68k-elf with a cf simulator, ok? OK with the changes above. I wouldn't mind some test cases, either! (In particlar for the merging logic). Cheers, Ben
