Subject: aarch64: Restrict SME_LUTv2 instructions to streaming mode
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=340e971f0ed62b8cab19bb2915fb3d8902b721de;p=thirdparty%2Fgcc.git

aarch64: Restrict SME_LUTv2 instructions to streaming mode

These instruction definitions were incorrectly missing their streaming
mode requirement.

gcc/ChangeLog:

	* config/aarch64/aarch64-sme.md
	(aarch64_sme_write_zt): Add TARGET_STREAMING requirement.
	(aarch64_sme_lut_zt): Ditto.
