mips.md: Adjust SI-mode "trap_if" instruction to use better predicates and constraints.
2003-08-19 Chris Demetriou <cgd@broadcom.com>
* config/mips/mips.md: Adjust SI-mode "trap_if" instruction
to use better predicates and constraints. Define new
instruction to handle "trap_if" with DI-mode arguments.
(conditional_trap): FAIL if trap code is not 0.
