optabs.c (emit_cmp_insn): Abort if asked to emit non-canonical RTL for a target with HAVE_cc0 defined.
* optabs.c (emit_cmp_insn): Abort if asked to emit non-canonical RTL
for a target with HAVE_cc0 defined.
(emit_cmp_and_jump_insns): New function.
* expr.h (emit_cmp_and_jump_insns): Prototype it.
* loop.c (check_dbra_loop): Use it to replace calls
to emit_cmp_insn and emit_jump_insn and to canonicalise
the comparison if necessary.
* unroll.c (unroll_loop): Likewise.
