I'm trying to get hold of a reliable documentation for the Apple assember ('as'), especially for the M1/M2 ARM architecture, but I suspect it's similar for x86 as well.
I found outdated links here:
But the new documentation site for Xcode (I assume this is where I would have to look) does not seem to have assembler documentation.
It's possible that apple uses the clang-llvm assembler, but it would then be nice to have an authoritative pointer to that documentation. Web searches seem futile for this subject :(
Thanks for any pointers.
