+ * dojump.c (compare_from_rtx): Delete.
+ * expmed.c (emit_store_flag): Only try cstore_optab. Canonicalize
+ any MODE_CC mode to the cstorecc4 pattern. Use prepare_operand, fail
+ if the comparison does not satisfy the predicate; test predicates for
+ operands 2 and 3 of a cstore pattern. Don't try cstore optab
+ further if one existing pattern fails.
+ * expr.h (compare_from_rtx): Delete.
+ (prepare_operand): Declare it.
+ * optabs.c: Change "lib call" to "libcall" throughout.

+ (prepare_float_lib_cmp): Return an rtx and a machine mode.
+ Accept other parameters by value.
+ (prepare_operand): Make non-static.

+ other parameters by value. Try to widen operands here based on
+ an optab_methods argument and looking at cbranch_optab.
+ (emit_cmp_and_jump_insn_1): Accept test and mode, remove widening loop.
+ Use cbranch_optab directly.
+ (emit_cmp_and_jump_insns): Fix comment. Adjust call to prepare_cmp_insn
+ and emit_cmp_and_jump_insn_1, remove obsolete assertion.
+ (emit_conditional_move, emit_conditional_add): Inline what's needed
+ of compare_from_rtx, using new prepare_cmp_insn for the rest.
+ (init_optabs): Init cmp_optab with UNKNOWN, cbranch_optab
+ with COMPARE. Move cmov_optab and cstore_optab above
+ with cbranch_optab, move cmp_optab down with ucmp_optab,
+ remove tst_otpab. Do not initialize trap_rtx.

+ for trap code. Do not check HAVE_conditional_trap. Use
+ prepare_cmp_insn. Accept no predicate for operand 3.
