Subject: IBM Z: Remove redundant V_HW_64 mode iterator.
X-Git-Tag: basepoints/gcc-13~5569
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4e34925ef1aeab73e022d80149be8cec92c48667;p=thirdparty%2Fgcc.git

IBM Z: Remove redundant V_HW_64 mode iterator.

gcc/ChangeLog:

	* config/s390/vector.md (V_HW_64): Remove mode iterator.
	(*vec_load_pair<mode>): Use V_HW_2 instead of V_HW_64.
	* config/s390/vx-builtins.md
	(vec_scatter_element<V_HW_2:mode>_SI): Use V_HW_2 instead of
	V_HW_64.
