Subject: AArch64: Implement vldrq_p128 intrinsic
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f2868e4bcff2c7b882d01231f039459c00e59d7b;p=gcc.git

AArch64: Implement vldrq_p128 intrinsic

This patch implements the missing vldrq_p128 intrinsic that just loads from the appropriate pointer.

Bootstrapped and tested on aarch64-none-linux-gnu.

gcc/
	PR target/71233
	* config/aarch64/arm_neon.h (vldrq_p128): Define.

gcc/testsuite/
	PR target/71233
	* gcc.target/aarch64/simd/vldrq_p128_1.c: New test.
