Update.
2000-05-17 Jakub Jelinek <jakub@redhat.com> * sysdeps/generic/dl-cache.h (_DL_CACHE_DEFAULT_ID): Only define if not yet defined. (_dl_cache_check_flags): Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/dl-cache.h: include_next dl-cache.h. 2000-05-17 Andreas Jaeger <aj@suse.de> * manual/creature.texi (Feature Test Macros): Remove paragraph since the description is wrong. Closes PR libc/1691, reported by Geoff Clare <gwc@unisoft.com>. 2000-05-17 Andreas Jaeger <aj@suse.de> * time/test_time.args: Removed. * time/Makefile (test_time-ARGS): Added contents here instead. * posix/tstgetopt.args: Removed. * posix/Makefile (tstgetopt-ARGS): Added contents here instead. * Rules: Allow arguments for test files to be specified in Makefile with testname-ARGS; remove rules with .args in it. * dirent/Makefile (opendir-tst1-ARGS): Use this for opendir-tst1, remove old bogus rule for opendir-tst1.args. * stdlib/test-canon.c: Rewrite to use test-skeleton.c. * stdlib/Makefile (test-canon-ARGS): New, supply argument to chdir into objdir. This allows a readonly sourcetree. Reported by lrgallardo@yahoo.com, closes PR libc/1421. 2000-05-16 Andreas Jaeger <aj@suse.de>, David Huggins-Daines <dhd@linuxcare.com> * sysdeps/generic/dl-cache.c (_dl_load_cache_lookup): Set cache_data in case of only new cache format correctly. * sysdeps/generic/dl-cache.c (_dl_load_cache_lookup): Align struct cache_file_new. * sysdeps/generic/dl-cache.h (ALIGN_CACHE): New macro to align struct cache_file_new. * elf/cache.c (save_cache): Fix str_offset if only new cache is present. * elf/cache.c (save_cache): Align struct new_file_cache. (print_cache): Likewise.
