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.
