Subject: Re: X32 project status update

Hi,

This is the x32 project status update:

https://sites.google.com/site/x32abi/

We have settled down on a preliminary system call number
scheme:

1. In kernel, x86-64 and x32 share the same system call slot if they
are the same.
2. First 512 system call slots are reserved for common and x86-64
specific ones. X32 specific system call slots start at 512.
3. All x32 system call numbers have the bit 30 set.

Gibc x32 binary rpms for Fedora 15/x86-64 are available from
the x32 website.  People can try out x32 on Fedora 15.

Thanks.
