Jakub Jelinek bcf89f05f7 i386: Fix up expander conditions on cbranchbf4 and cstorebf4 [PR107969]
With -msoft-float we ICE on __bf16 comparisons, because the
insns we want to use under the hood (cbranchsf4 and cstoresf4)
after performing the fast extensions aren't available.

The following patch copies the conditions from the c*sf4 expanders
to the corresponding c*bf4 expanders.

2022-12-06  Jakub Jelinek  <jakub@redhat.com>

	PR target/107969
	* config/i386/i386.md (cbranchbf4, cstorebf4): Guard expanders
	with the same condition as cbranchsf4 or cstoresf4 expanders.

	* gcc.target/i386/pr107969.c: New test.

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,
