	PR target/91154
	* config/i386/i386-features.h (scalar_chain::scalar_chain): Add
	mode arguments.
	(scalar_chain::smode): New member.
	(scalar_chain::vmode): Likewise.
	(dimode_scalar_chain): Rename to...
	(general_scalar_chain): ... this.
	(general_scalar_chain::general_scalar_chain): Take mode arguments.
	(timode_scalar_chain::timode_scalar_chain): Initialize scalar_chain
	base with TImode and V1TImode.
	* config/i386/i386-features.c (scalar_chain::scalar_chain): Adjust.
	(general_scalar_chain::vector_const_cost): Adjust for SImode
	chains.
	(general_scalar_chain::compute_convert_gain): Likewise.  Add
	{S,U}{MIN,MAX} support.
	(general_scalar_chain::replace_with_subreg): Use vmode/smode.
	(general_scalar_chain::make_vector_copies): Likewise.  Handle
	non-DImode chains appropriately.
	(general_scalar_chain::convert_reg): Likewise.
	(general_scalar_chain::convert_op): Likewise.
	(general_scalar_chain::convert_insn): Likewise.  Add
	fatal_insn_not_found if the result is not recognized.
	(convertible_comparison_p): Pass in the scalar mode and use that.
	(general_scalar_to_vector_candidate_p): Likewise.  Rename from
	dimode_scalar_to_vector_candidate_p.  Add {S,U}{MIN,MAX} support.
	(scalar_to_vector_candidate_p): Remove by inlining into single
	caller.
	(general_remove_non_convertible_regs): Rename from
	dimode_remove_non_convertible_regs.
	(remove_non_convertible_regs): Remove by inlining into single caller.
	(convert_scalars_to_vector): Handle SImode and DImode chains
	in addition to TImode chains.
	* config/i386/i386.md (<maxmin><MAXMIN_IMODE>3): New expander.
	(*<maxmin><MAXMIN_IMODE>3_1): New insn-and-split.
	(*<maxmin>di3_doubleword): Likewise.

	* gcc.target/i386/pr91154.c: New testcase.

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
