*	aarch64: MTE compatible memrchr	Alex Butler	2020-06-23	1	-116/+83
\| \| \| \| \| \| \| \| \| \| \| \|	Add support for MTE to memrchr. Regression tested with xcheck and benchmarked with glibc's benchtests on the Cortex-A53, Cortex-A72, and Neoverse N1. The existing implementation assumes that any access to the pages in which the string resides is safe. This assumption is not true when MTE is enabled. This patch updates the algorithm to ensure that accesses remain within the bounds of an MTE tag (16-byte chunks) and improves overall performance.

*	aarch64: Optimized implementation of memrchr	Xuelei Zhang	2019-12-19	1	-0/+165
	Considering the excellent performance of memchr.S on glibc 2.30, the same algorithm is used to find chrin. Compared to memrchr.c, this method with memrchr.S achieves an average performance improvement of 58% based on benchtest and its extension cases. Checked on aarch64-linux-gnu.
