This is the PR for issue #378. Copy pasting from the issue:
This PR changes those memory functions to weak symbols, so users can override them if they want for specific purpose or better performance.
For example, in our project https://git.m-labs.hk/pca006132/artiq-zynq/src/branch/test, we overrided the
aeabi_memcpy*
functions with an implementation from newlib which uses NEON instructions for faster memcpy.
