This is a series of commits which culminates in the update to Musl 1.2.6. In order to make this a bit more automatic in the future as well I've setup the git history here to be able to use the
git subtreecommand in the future. Thelibc-top-half/README.mdfile documents this information and how to update in the future, along with what I've executed for this PR.The commits here are intended to stay separate and I'll use a "merge" strategy with this PR rather than squash & merge since the git commit history is intended to be important. Specifically what this is doing is:
libc-top-half/musldirectory is deleted entirely, including all changes made for wasi-libc.git subtree add. This creates themusldirectory in a pristine state at 1.2.5main, meaning that the diff from main is nothing. Git history is in place though forgit subtreegit subtree pullto update to Musl 1.2.6. I've edited the merge commit myself quite a bit to resolve conflicts.The end result is that
git subtree pullcan be used in the future to update the musl subtree with conflict markers and everything making it easy to see what changed.
