It basically removes the alpha assembly version which call the old sigsusped interface using only the first doubleword from sigset. Current minimum supported kernel on alpha (3.2) enforces rt_sigsuspend on the architecture (__ARCH_WANT_SYS_RT_SIGSUSPEND option on kernel), so it is possible to use the default implementation. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, arch64-linux-gnu, arm-linux-gnueabihf, powerpc64le-linux-gnu, sparc64-linux-gnu, and sparcv9-linux-gnu. * sysdeps/unix/sysv/linux/alpha/sigsuspend.S: Remove file. * sysdeps/unix/sysv/linux/sigsuspend.c: Simplify include list. --- ChangeLog | 3 +++ sysdeps/unix/sysv/linux/alpha/sigsuspend.S | 32 ------------------------------ sysdeps/unix/sysv/linux/sigsuspend.c | 4 ---- 3 files changed, 3 insertions(+), 36 deletions(-) delete mode 100644 sysdeps/unix/sysv/linux/alpha/sigsuspend.S diff --git a/sysdeps/unix/sysv/linux/alpha/sigsuspend.S b/sysdeps/unix/sysv/linux/alpha/sigsuspend.S deleted file mode 100644 index c226be1..0000000 --- a/sysdeps/unix/sysv/linux/alpha/sigsuspend.S +++ /dev/null @@ -1,32 +0,0 @@ -/* Copyright (C) 1993-2017 Free Software Foundation, Inc. - This file is part of the GNU C Library. - Contributed by David Mosberger , 1995. - - 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.
