Subject: aarch64: Fix up flags for vget_low_*, vget_high_* and vreinterpret intrinsics
X-Git-Tag: basepoints/gcc-16~3749
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b35f9c2535a34279898bf8795e748161fd1704ed;p=thirdparty%2Fgcc.git

aarch64: Fix up flags for vget_low_*, vget_high_* and vreinterpret intrinsics

These 3 intrinsics will not raise an fp exception, or read FPCR. These intrinsics,
will be folded into VIEW_CONVERT_EXPR or a BIT_FIELD_REF which is already set to
be const expressions too.

Built and tested for aarch64-linux-gnu.

gcc/ChangeLog:

	* config/aarch64/aarch64-builtins.cc (VREINTERPRET_BUILTIN): Use
	FLAG_NONE instead of FLAG_AUTO_FP.
	(VGET_LOW_BUILTIN): Likewise.
	(VGET_HIGH_BUILTIN): Likewise.
