[Xtensa] add extra check in GAS
Wed Jul 25 18:25:00 GMT 2007
The Xtensa EXTUI opcode has undefined behavior if its two immediate
operands sum to greater than 32. I've committed this patch from
Sterling Augustine to check for that condition.

* config/tc-xtensa.c (xtensa_extui_opcode): New.
(xg_expand_assembly_insn): Check for invalid extui operands.
(md_begin): Initialize xtensa_extui_opcode.
