Hi All,

I am looking for a ABI Documentation of the X86 architecture to understand how LLVM converts its IR to X86 target instructions. Please guide me from where i can get the resources.

Thanks,

Unfortunately, x86-64.org has been unavailable since at least the beginning of the year, so the normal location for the spec is no longer useful. Attached is the latest version I have.
