Update.
2001-04-18 Jakub Jelinek <jakub@redhat.com>
* sysdeps/sparc/sparc64/fpu/libm-test-ulps: Update.
* sysdeps/unix/sysv/linux/sparc/sparc64/makecontext.c: New file.
* sysdeps/unix/sysv/linux/sparc/sparc64/swapcontext.c: New file.
* sysdeps/unix/sysv/linux/sparc/sparc64/setcontext.S (__setcontext):
Copy first word of uc_sigmask into __uc_sigmask.
* sysdeps/unix/sysv/linux/sparc/sparc64/getcontext.S (__getcontext):
Save uc_link around trap. Copy __uc_sigmask into first word of
uc_sigmask, clear the rest. Make sure setcontext to the created
context doesn't do this though.
* sysdeps/unix/sysv/linux/sparc/sparc64/ucontext_i.h: New file.
* sysdeps/unix/sysv/linux/sparc/sys/ucontext.h (ucontext_t): Add
uc_stack and uc_sigmask, rename old uc_sigmask to __uc_sigmask in the
64bit version, make uc_sigmask __sigset_t in the 32bit version.
* rt/Makefile (otherlibs): Added for static NSS.
* glibcbug.in (BUGGLIBC): Send to new alias.
