From 7f33b09c65e3fdb6b6a1af8816918bcce977b38a Mon Sep 17 00:00:00 2001 From: Palmer Dabbelt Date: Mon, 29 Jan 2018 10:28:32 -0800 Subject: RISC-V: Linux ABI Linux-specific code that is required for maintaining ABI compatibility. This doesn't contain the actual system call interface, that is split out in order to avoid having a patch that's too big. 2018-01-29 Palmer Dabbelt * sysdeps/riscv/nptl/pthread-offsets.h: New file. * sysdeps/riscv/nptl/pthreaddef.h: Likewise. * sysdeps/unix/sysv/linux/riscv/bits/fcntl.h: Likewise. * sysdeps/unix/sysv/linux/riscv/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/riscv/bits/sigcontext.h: Likewise. * sysdeps/unix/sysv/linux/riscv/dl-cache.h: Likewise. * sysdeps/unix/sysv/linux/riscv/flush-icache.c: Likewise. * sysdeps/unix/sysv/linux/riscv/getcontext.S: Likewise. * sysdeps/unix/sysv/linux/riscv/init-first.c: Likewise. * sysdeps/unix/sysv/linux/riscv/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/riscv/makecontext.c: Likewise. * sysdeps/unix/sysv/linux/riscv/readelflib.c: Likewise. * sysdeps/unix/sysv/linux/riscv/register-dump.h: Likewise. * sysdeps/unix/sysv/linux/riscv/setcontext.S: Likewise. * sysdeps/unix/sysv/linux/riscv/sigcontextinfo.h: Likewise. * sysdeps/unix/sysv/linux/riscv/swapcontext.S: Likewise. * sysdeps/unix/sysv/linux/riscv/sys/cachectl.h: Likewise. * sysdeps/unix/sysv/linux/riscv/sys/procfs.h: Likewise. * sysdeps/unix/sysv/linux/riscv/sys/ucontext.h: Likewise. * sysdeps/unix/sysv/linux/riscv/sys/user.h: Likewise. * sysdeps/unix/sysv/linux/riscv/ucontext-macros.h: Likewise. * sysdeps/unix/sysv/linux/riscv/ucontext_i.sym: Likewise. --- sysdeps/unix/sysv/linux/riscv/ucontext-macros.h | 49 +++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/riscv/ucontext-macros.h (limited to 'sysdeps/unix/sysv/linux/riscv/ucontext-macros.h') diff --git a/sysdeps/unix/sysv/linux/riscv/ucontext-macros.h b/sysdeps/unix/sysv/linux/riscv/ucontext-macros.h new file mode 100644 index 0000000000..a73c3a9b04 --- /dev/null +++ b/sysdeps/unix/sysv/linux/riscv/ucontext-macros.h @@ -0,0 +1,49 @@ +/* Macros for ucontext routines. + Copyright (C) 2017-2018 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + 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.
