Subject: [PATCH, i386]: Use GET_MODE_BITSIZE in shift splitters

Hello!

2010-09-21  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/i386.c (ix86_split_ashl): Rename single_width variable
	to half_width.  Use GET_MODE_BITSIZE to calculate mode size.
	(ix86_split_ashr): Ditto.
	(ix86_split_lshr): Ditto.

Tested on x86_64-pc-linux-gnu {,-m32}. Committed to mainline SVN.

Uros.
