I get the feeling I am missing some background.
Which architecture is this?
Are the ports already upstream in binutils/gas/gcc?
Do you also have a new elfutils ebl backend for it?
After your changes, how well does the testsuite work?
I am a little afraid the configure logic might become somewhat
fragile. Ulrich's suggestion to just use a different syntax for
your instruction set does make sense to me.
Thanks,
Mark
