They're DImode already, but I did figure out a workaround that reduces
it to 16 SETs, so I'm all set.

Perhaps you can cheat by using larger modes. E.g., if it's a 32-bit
machine, using DImode will cut the number of operands in half.

The opcode swaps two register banks. 32 SETs total.

Or used "ch-'a' < 32" tests, but would that work with EBCDIC build
machines?

That so
genrecog uses strings to keep track of where it is, specifically,
digits and letters. I've got an insn that writes to more than 26
registers. Would switching to something bigger than [A-Z] be
difficult? Perhaps using Japanese letters instead of English? ;-)
