Richard Biener 3457dae55f middle-end/96453 - relax gimple_expand_vec_cond_expr
This relaxes the condition under which we also try NE_EXPR
for a fake generated compare in addition to LT_EXPR given
the fact the verification ICEd when it failed but obviously
was only implemented for constants.  Thus the patch removes
the verification and the restriction to constant operands.

2020-09-23  Richard Biener  <rguenther@suse.de>

	PR middle-end/96453
	* gimple-isel.cc (gimple_expand_vec_cond_expr): Remove
	LT_EXPR -> NE_EXPR verification and also apply it for
	non-constant masks.

	* gcc.dg/pr96453.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.
