;; Compare instructions.
;; This controls RTL generation and register allocation.

;; We generate RTL for comparisons and branches by having the cmpxx 
;; patterns store away the operands.  Then, the scc and bcc patterns
;; emit RTL for both the compare and the branch.
;;
;; We do this because we want to generate different code for an sne and
;; seq insn.  In those cases, if the second operand of the compare is not
;; const0_rtx, we want to compute the xor of the two operands and test
;; it against zero.
;;
;; We start with the DEFINE_EXPANDs, then the DEFINE_INSNs to match
;; the patterns.  Finally, we have the DEFINE_SPLITs for some of the scc
;; insns that actually require more than one machine instruction.

;; Put cmpsi first among compare insns so it matches two CONST_INT operands.
