x64 ABI document?

NTDEV
1

Does anyone know of an ABI document for Windows on x64 machines that
specifies the standard usages of registers? There are some obvious
conventions here, and what appear to be some implicit requirements in the
x64 hardware documentation. But I’ve never been able to find anything
similar to this for any Intel architecture.

I know that IA-64 had a very elaborate document of this sort. However, that
doesn’t help much with more modern processors!

Thanks

Loren

If you’re asking about the calling convention, most of it is documented in
the Windbg documentation. Look under processor architectures.
