To: patches, gcc
This patch adds the support needed for gcc to be set up for x86-64 support.
gcc couldn't bootstrap before I added this, so I couldn't do any testing.
There shouldn't be anything here that affects i386 or any other arch though.
Bo.
2001-09-20 Bo Thorsen <bo@suse.co.uk>
* config/i386/linux64.h: New spec file for Linux x86-64 support.
* config.gcc: Fix tm_file settings for x86-64.
* config/i386/x86-64.h: New file with OS independent x86-64
definitions.
* config/i386/att.h: Add ASM_X definitions for x86-64.

I just successfully bootstrapped it on i386. Can I commit this?
