Subject: [Xtensa] add extra check in GAS

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.

Attachment: gas-extui-check.patch
Description: Binary data
