2001-03-16 David Mosberger <davidm@hpl.hp.com> * sysdeps/unix/sysv/linux/ia64/bits/sigcontext.h (struct sigcontext): Drop hack that was needed for 2.1.1 kernel headers. * sysdeps/unix/sysv/linux/ia64/ucontext_i.h: New file. * sysdeps/unix/sysv/linux/ia64/sys/ucontext.h: Rewrite to make it overlay with kernel's "struct sigcontext". * sysdeps/unix/sysv/linux/ia64/Makefile (sysdep_headers): Add sys/rse.h for "misc" subdir. (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.
