2006-10-25  Richard Guenther  <rguenther@suse.de>

	* optabs.h (enum optab_index): Remove OTI_lrint.
	(enum convert_optab_index): Add COI_lrint.
	(lrint_optab): Adjust.
	(expand_sfix_optab): Declare.
	* optabs.c (expand_sfix_optab): New function.
	(init_optabs): Init lrint_optab as conversion optab.
	* genopinit.c (lrint_optab): Change to a conversion optab.
	* builtins.c (expand_builtin_int_roundingfn_2): Adjust to
	expansion via conversion optab.
	* config/i386/i386.md (*fistdi2_1): Remove
	flag_unsafe_math_optimizations guard.
	(fistdi2, fistdi2_with_temp, *fist<mode>2_1, fist<mode>2,
	fist<mode>2_with_temp): Likewise.
	(lrint<mode>2): Split into...
	(lrintxf<mode>2): ... x87 part
	(lrint<mode>di2, lrint<mode>si2): ... and SSE parts.
	* config/i386/sse.md (sse_cvtss2si_2, sse_cvtss2_siq_2,
	sse2_cvtsd2si_2, sse2_cvtsd2siq_2): New insns for
	UNSPEC_FIX_NOTRUNC matching non-vector float modes.
	* doc/md.texi (lrintMN2): Document.
