Switch to Arm Optimized Routines for mem* & str* 2021-11-19T11:40:46+00:00 Andrew Turner andrew@FreeBSD.org 2021-11-01T13:06:56+00:00 2e8ff4d1d5b9d32b29287efb414449121733544a These are the updated version of the older Cortex Strings Library we previously used. The Arm Optimized Routines also support CPU features that are currently in development on FreeBSD, e.g. Branch Target Identification (BTI). Rather than add BTI support to the old code it's easier to just use the maintained version. Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D32774
