Subject: aarch64: Add attributes to the data intrinsics.
X-Git-Tag: basepoints/gcc-16~3747
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4c46ad730acf8c119a99210c1485b456cdb06f19;p=thirdparty%2Fgcc.git

aarch64: Add attributes to the data intrinsics.

All of the data intrinsics don't read/write memory nor they are fp related.
So adding the attributes will improve the code generation slightly.

Built and tested for aarch64-linux-gnu

gcc/ChangeLog:

	* config/aarch64/aarch64-builtins.cc (aarch64_init_data_intrinsics): Call
	aarch64_get_attributes and update calls to aarch64_general_add_builtin.
