[PATCH] add FreeBSD/IA-64 to gcc 3.0.3
- To: gcc-patches at gcc dot gnu dot org
- Subject: [PATCH] add FreeBSD/IA-64 to gcc 3.0.3
- From: "David O'Brien" <obrien at FreeBSD dot org>
- Date: Sat, 27 Oct 2001 13:40:16 -0700
- Organization: The NUXI BSD group
- Reply-To: obrien at FreeBSD dot org
I would like to commit this to the gcc-3_0-branch. We need this for
FreeBSD's porting effort to the IA-64.
I configured both stock and with my changes each of "ia64-unknown-linux",
"ia64-unknown-elf", and "ia64-unknown-hpux" and varied no change in the
output of 'gcc -E' ran on the created tm.h.
Permission to commit?
