Subject: [i386] APX: Fix EGPR usage in several patterns.
X-Git-Tag: basepoints/gcc-15~4626
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9251db0dabc8e75c31b49a5b589124e9a2bc8299;p=thirdparty%2Fgcc.git

[i386] APX: Fix EGPR usage in several patterns.

For vextract/insert{if}128 they cannot adopt EGPR in their memory operand, all
related pattern should be adjusted to disable EGPR usage on them.
Also fix a wrong gpr16 attr for insertps.

gcc/ChangeLog:

	* config/i386/sse.md (vec_extract_hi_<mode>): Add noavx512vl
	alternative with attr addr gpr16 and "jm" constraint.
	(vec_extract_hi_<mode>): Likewise for SF vector modes.
	(@vec_extract_hi_<mode>): Likewise.
	(*vec_extractv2ti): Likewise.
	(vec_set_hi_<mode><mask_name>): Likewise.
	* config/i386/mmx.md (@sse4_1_insertps_<mode>): Correct gpr16 attr for
	each alternative.
