Subject: [i386] : Remove unneeded comparison code iterators
From: Uros Bizjak <ubizjak@gmail.com>

Hello!

These code iterators are unused.  Also, the patch changes
"comparison_operator" to "ordered_comparison_operator" for
integer-only patterns.

2010-07-29  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/i386.md (int_cond): Remove code iterator.
	(fp_cond): Ditto.
	(cbranch<mode>4): Use ordered_comparison_operator predicate
	for operator0.
	(cstore<mode>4): Ditto for operator1.
	(mov<SWIM:mode>cc): Ditto.

Bootstrapped and regression tested on x86_64-pc-linux-gnu {,-m32} and
committed to mainline SVN.

Uros.
