Update.
2002-08-29 Jakub Jelinek <jakub@redhat.com> * stdio-common/vfprintf.c (vfprintf): Add builtin_expect for string_malloced, it is unlikely to be set. Only call free with non-NULL workspace. * sysdeps/sparc/sparc32/sparcv9/Makefile (sysdep-CFLAGS): Use -mcpu=ultrasparc, not only tune for it. (ASFLAGS*): Set unconditionally. 2002-08-29 Jakub Jelinek <jakub@redhat.com> * sysdeps/generic/readelflib.c (process_elf_file): Make loadaddr ElfW(Addr). Don't mask upper 32-bits and lower 12 bits off from p_vaddr/p_offset when computing loadaddr.
