where is amd64 psABI? [duplicate]

Question

The AMD64 psABI used to be hosted at x86-64.org.

I have a copy of pdf file and it says explicitly:

The architecture specification is available on the web at http://www.x86-64.org/documentation.

but http://www.x86-64.org is down for a long time already. Several months at least.

Does anyone know where the latest psABI can be taken from?

Answer 1

See http://refspecs.linuxfoundation.org/

System V psABI for x86_64 architecture: http://refspecs.linuxfoundation.org/elf/x86_64-abi-0.95.pdf

EDIT: 0.99.6 seems to be the latest one, select any from https://www.google.com/search?q=System+V+Application+Binary+Interface+AMD64+0.99.6
