* genrecog.c (OUTPUT_LABEL, write_tree_1, write_tree): When
generating labels, mark them with ATTRIBUTE_UNUSED_LABEL.
* invoke.texi: Note that labels can be marked `unused'.

* 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.

From-SVN: r24471
* pa.md (branch, negated branch): Handle (const_int 0) as first
source operand.
