Yes, I know it sounds like the 'bride of Frankenstein' type of request, but...

Has anyone produced an IBM 370-ish gcc, or perhaps investigated issues
surrounding getting gcc to work with a big cisc instruction set from IBM?
Any thoughts or experiences would be appreciated!

[The 370 instruction set is actually pretty easy to deal with if you disregard
the Cobol instructions. What's harder is handling the 4K limit on address
offsets and the need to use a base register for branches. I note there's a
commented out entry for the 370 in gcc.config. -John]
