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. 2016-11-09 Joseph Myers * sysdeps/unix/sysv/linux/ia64/tst-setcontext2.c: New file. 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 0000000..7adc059 --- /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.
