Mon Aug 12 03:31:58 1996 Ulrich Drepper <drepper@cygnus.com> * nss/nsswitch.c (__nss_configure_lookup): New function. Allows to specify services. * nss/XXX-lookup.h: Rename database variable and make global. * nss/databases.def: New file. Real names of all databases. * nss/nss.h: New file. Contains declaration useful for users and service developers. * nss/nsswitch.h: Move some declarations to nss/nss.h. * nss.h: New file. Wrapper around nss/nss.h. * nss/Makefile (headers): Add nss.h. (distributes): Add databases.h. Sun Aug 11 16:19:42 1996 Ulrich Drepper <drepper@cygnus.com> Help the poor people with fast machines by making sure only one `ar' commands works on the library. * autolock.sh: New file. Written by Tom Tromey. * Makerules (do-ar): Call autolock.sh shell script instead of directly using `ar'. * config.make.in: Make configuration variable AUTOLOCK which gets initialized by configure. * configure.in: Define variable AUTOLOCK to point to autolock.sh script and mark it to substitute. * string/Makefile: Add -fno-builtin for tst-strlen.c, too. * elf/dl-lookup.c (_dl_lookup_symbol): Allow self-referencing. Patch by David Mosberger-Tang. Sun Aug 11 01:12:38 1996 Richard Henderson <rth@tamu.edu> * sysdeps/alpha/dl-machine.h (elf_alpha_fix_plt): Optimize LD_BIND_NOW startup by moving Icache flush from here ... (ELF_MACHINE_RUNTIME_TRAMPOLINE): ... to here. (ELF_MACHINE_USER_ADDRESS_MASK): Delete; it is unused. * sysdeps/alpha/divrem.h: Update comment to reflect the actual calling conventions. The code is already correct. Sun Aug 11 01:06:42 1996 Richard Henderson <rth@tamu.edu> * string/Makefile: Compile tester with -fno-builtin as we want to test our implementations, not gcc's.
