S glibc glibc-2 on KDAB Codebrowser Generated on 2026-Feb-08 from project glibc revision glibc-2. 8 extension adds new instructions to perform memcpy(), memset() and memmove() operations in Experimental memcpy speed toolkit for ARM CPUs. 7a is the next closest choice. 8-A and Armv9. c at master · ARM-software/optimized-routines 22 March 2017 by Phillip Johnston • Last updated 15 December 2021 We need to knock out many more libc functions before we can start with our C++ runtime bringup.
