The porting effort of the SIMD enhanced libc string functions from amd64 to aarch64 has been successfully completed. | ||
There are now optimized implementations for 16 libc string functions in addition to those with implementations already available as part of the ARM optimized subroutines library. | ||
There is also a presentation regarding the general method for these methods from EuroBSDCon 2024 available on YouTube with a short description in the end of how the porting has been done with regards to the aarch64 architecture. | ||
|
||
These enhancements significantly improve performance of string functions for all FreeBSD systems on the aarch64 platform. | ||
|
||
The code is currently undergoing acceptance testing in the form of an exp-run building all the ports, once without and once with the patch set applied to see if it has caused any new failures. | ||
