Hello!

ix86_binary_operator_ok needs output operand in addition to two input operands.

2010-08-18  Uros Bizjak  <ubizjak@gmail.com>

	PR target/45327
	* config/i386/i386.md (<any_or:code><SWI:mode>_3): Do not use
	ix86_binary_operator_ok.

Tested on x86_64-pc-linux-gnu and committed to 4.5 and SVN mainline.

Uros.
