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.
