From 0934f142036f12292711770d353f1c01ab718db7 Mon Sep 17 00:00:00 2001 From: "\"Jan-Benedict Glaw\"" Date: Fri, 27 Jan 2006 21:20:28 +0000 Subject: First round of VAX patches. This isn't complete right now, there are for sure still bugs (properly hidden, of course), a libm is completely missing (I've got one that implements some basic stuff, but that's really not ready for checking in...) I've also got a list of other things that need touch-ups, but that's mostly minor stuff that'll be done during the next days. --- libc/sysdeps/linux/vax/bits/machine-gmon.h | 41 ++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 libc/sysdeps/linux/vax/bits/machine-gmon.h (limited to 'libc/sysdeps/linux/vax/bits/machine-gmon.h') diff --git a/libc/sysdeps/linux/vax/bits/machine-gmon.h b/libc/sysdeps/linux/vax/bits/machine-gmon.h new file mode 100644 index 000000000..841518f06 --- /dev/null +++ b/libc/sysdeps/linux/vax/bits/machine-gmon.h @@ -0,0 +1,41 @@ +/* i386-specific implementation of profiling support. + Copyright (C) 1997, 2002 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Ulrich Drepper , 1997. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
