From b3daf3ee099d6c1e1e04a08221a6f68e79ced834 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 28 Nov 2016 23:13:46 +0000 Subject: [PATCH] Work around IA64 tst-setcontext2.c compile failure. Building tests for IA64 runs into a build failure compiling stdlib/tst-setcontext2.c: tst-setcontext2.c: In function 'do_test': tst-setcontext2.c:210:20: error: passing argument 1 of 'sigismember' from incompatible pointer type [-Werror=incompatible-pointer-types] if (sigismember (&oldctx.uc_sigmask, SIGUSR2) != 1) ^ Indeed, the IA64 uc_sigmask as unsigned long rather than the larger userspace sigset_t. Fixing this might be hard; this patch works around the build failure by making IA64 wrap the test with a version that #defines sigismember to add a cast (I'd welcome a better approach for fixing this). Tested (compilation only) for ia64. * sysdeps/unix/sysv/linux/ia64/tst-setcontext2.c: New file. --- ChangeLog | 2 ++ .../unix/sysv/linux/ia64/tst-setcontext2.c | 24 +++++++++++++++++++ 2 files changed, 26 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/ia64/tst-setcontext2.c diff --git a/ChangeLog b/ChangeLog index 6d9b1629a6..591b4c0cac 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,7 @@ 2016-11-28 Joseph Myers + * sysdeps/unix/sysv/linux/ia64/tst-setcontext2.c: New file. + * sysdeps/ia64/fpu/libm-symbols.h: Make contents conditional on [!__STRICT_ANSI__ && !__cplusplus]. diff --git a/sysdeps/unix/sysv/linux/ia64/tst-setcontext2.c b/sysdeps/unix/sysv/linux/ia64/tst-setcontext2.c new file mode 100644 index 0000000000..7adc059440 --- /dev/null +++ b/sysdeps/unix/sysv/linux/ia64/tst-setcontext2.c @@ -0,0 +1,24 @@ +/* Work around incorrect type of IA64 uc_sigmask. + Copyright (C) 2016 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.
