No, I was asking if you meant the whole port-in-progress or if you were only asking about said functions; at that point I had not checked. At present, I can tell you what the git log says: -memcpy.c was last touched in August last year implementing a portable optimized memcpy. -abs.c has not changed in the 3 years of git history -sprintf.c (I assume that's what you mean by 'sprint'?) has not been touched since 2012. ...all of which are before AArch64 porting.

At present, I can tell you what the git log says: -memcpy.c was last touched in August last year implementing a portable optimized memcpy. -abs.c has not changed in the 3 years of git history -sprintf.c (I assume that's what you mean by 'sprint'?) has not been touched since 2012. ...all of which are before AArch64 porting. Is the relevant code in 'rebase-1.0'?

Rather than trying to answer point by point I'll try to explain a few things: It's not possible to use musl on a new arch simply by compiling the arch-independent C. This is partly because there are a number of components of libc that fundamentally cannot be expressed in C, and partly because the kernel (gratuitously) has a different set of constants, struct definitions, etc. for each architecture. Generally ports are not merged (in the "git merge" sense) because most of the early work on them is a mess of incompleteness, trial-and-error, etc. Also merging would be a lot of work since we normally rebase all merges, whereas master has often diverged quite a bit before a port is ready to merge. Instead, once the port is working, we usually just add it as a single commit, followed by any fixes for issues that weren't found before commit. I'm not clear on the status of the aarch64 port right now. It was stalled for a while because of changes needed in many of the arch-independent files to accomodate the way the kernel does things on newer archs (omitting lots of simple syscalls that can be emulated using more complex ones). That work is done in mainline musl now though, so it's no longer blocking ports. Further progress is up to the people working on those ports (or anyone else who wants to build on their work). I'm really hoping it will be finished during this release cycle so we can have aarch64 support in 1.1.4. If you or anyone else wants to play around with trying to get it to work based on the in-progress ports, the best approach would be to simply copy over the new files added in the aarch64 musl git tree into a more recent musl (1.1.2 or later).

It should match the definitions from the kernel, but definitions for any syscalls that do not actually exist on aarch64 need to be removed.
