From 041cdc2769407c4d3869b218ad7ee7638e1c306e Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Wed, 24 May 2017 20:49:02 +0200 Subject: sparc64: add basic support No NPTL, no LDSO support. Bootup with Busybox Ash in Qemu working. Testuite shows only two failures, but mksh continue/break support doesn't work. --- libc/sysdeps/linux/sparc64/sys/procfs.h | 121 +++++++++++++++ libc/sysdeps/linux/sparc64/sys/ptrace.h | 235 ++++++++++++++++++++++++++++++ libc/sysdeps/linux/sparc64/sys/ucontext.h | 198 +++++++++++++++++++++++++ libc/sysdeps/linux/sparc64/sys/user.h | 83 +++++++++++ 4 files changed, 637 insertions(+) create mode 100644 libc/sysdeps/linux/sparc64/sys/procfs.h create mode 100644 libc/sysdeps/linux/sparc64/sys/ptrace.h create mode 100644 libc/sysdeps/linux/sparc64/sys/ucontext.h create mode 100644 libc/sysdeps/linux/sparc64/sys/user.h (limited to 'libc/sysdeps/linux/sparc64/sys') diff --git a/libc/sysdeps/linux/sparc64/sys/procfs.h b/libc/sysdeps/linux/sparc64/sys/procfs.h new file mode 100644 index 000000000..c1dfb1980 --- /dev/null +++ b/libc/sysdeps/linux/sparc64/sys/procfs.h @@ -0,0 +1,121 @@ +/* Copyright (C) 1996, 1997, 1999, 2000 Free Software Foundation, Inc. + + 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.
