[PATCH, i386]: Macroize bitops


Hello!

2010-04-20  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/i386.md (ffs<mode>2): Macroize expander from ffs_cmove
	and ffsdi2 using SWI48 mode iterator.  Expand SImode insn through
	ffsi2_no_cmove for !TARGET_CMOVE.
	(ffssi2_no_cmove): Rename from *ffs_no_cmove.  Make public.
	(ffssi2): Remove expander.
	(*ffs<mode>_1): Macroize insn from *ffs{si,di} using SWI48
	mode iterator.
	(ctz<mode>2): Ditto from ctz{si,di}2.
	(clz<mode>2): Macroize expander from ctz{hi,si,di}2 using SWI248
	mode iterator.
	(clz<mode>2_abm): Macroize insn from clz{hi,si,di}2_abm using SWI248
	mode iterator.

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

Uros.
