(sysdep_routines): Add __start_context for "stdlib" subdir. * sysdeps/unix/sysv/linux/ia64/sys/rse.h: New file (based on kernel file of the same name). * stdlib/Makefile (tests): Add tst-setcontext. * stdlib/tst-setcontext.c: New file (based on a sample program by Uli Drepper). * sysdeps/unix/sysv/linux/ia64/setcontext.S: New file. * sysdeps/unix/sysv/linux/ia64/getcontext.S: New file. * sysdeps/unix/sysv/linux/ia64/__start_context.S: New file. * sysdeps/unix/sysv/linux/ia64/makecontext.c: New file. * sysdeps/unix/sysv/linux/ia64/__longjmp.S (__longjmp): Use extr.u instead of shift & and. --- sysdeps/unix/sysv/linux/ia64/ucontext_i.h | 58 +++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/ia64/ucontext_i.h (limited to 'sysdeps/unix/sysv/linux/ia64/ucontext_i.h') diff --git a/sysdeps/unix/sysv/linux/ia64/ucontext_i.h b/sysdeps/unix/sysv/linux/ia64/ucontext_i.h new file mode 100644 index 0000000000..fc51662052 --- /dev/null +++ b/sysdeps/unix/sysv/linux/ia64/ucontext_i.h @@ -0,0 +1,58 @@ +/* Copyright (C) 2001 Free Software Foundation, Inc. + Contributed by David Mosberger-Tang . + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Library General Public License as + published by the Free Software Foundation; either version 2 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.
