From 2ad7600be76ada35c6e9f0baa75bc96252785268 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 10 Feb 2014 23:30:21 +0000 Subject: Move mips from ports to libc. I've moved the MIPS port from ports to the main sysdeps hierarchy. Beyond the README update, the move of the files was simply git mv ports/sysdeps/mips sysdeps/mips git mv ports/sysdeps/unix/mips sysdeps/unix/mips git mv ports/sysdeps/unix/sysv/linux/mips sysdeps/unix/sysv/linux/mips and in addition to the ChangeLog entries here, I put a note at the top of ports/ChangeLog.mips similar to those in other files. Tested that disassembly of installed shared libraries for mips is the same before and after this patch (except for ld.so where paths in assertions are involved, as for arm). * sysdeps/mips: Move directory from ports/sysdeps/mips. * sysdeps/unix/mips: Move directory from ports/sysdeps/unix/mips. * sysdeps/unix/sysv/linux/mips: Move directory from ports/sysdeps/unix/sysv/linux/mips. * README: Update listing for mips-*-linux-gnu and mips64-*-linux-gnu. * sysdeps/mips: Move directory to ../sysdeps/mips. * sysdeps/unix/mips: Move directory to ../sysdeps/unix/mips. * sysdeps/unix/sysv/linux/mips: Move directory to ../sysdeps/unix/sysv/linux/mips. --- sysdeps/unix/sysv/linux/mips/register-dump.h | 121 +++++++++++++++++++++++++++ 1 file changed, 121 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/mips/register-dump.h (limited to 'sysdeps/unix/sysv/linux/mips/register-dump.h') diff --git a/sysdeps/unix/sysv/linux/mips/register-dump.h b/sysdeps/unix/sysv/linux/mips/register-dump.h new file mode 100644 index 0000000000..86c530f887 --- /dev/null +++ b/sysdeps/unix/sysv/linux/mips/register-dump.h @@ -0,0 +1,121 @@ +/* Dump registers. + Copyright (C) 2000-2014 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Andreas Jaeger , 2000. + + 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.
