Update.
2004-03-06 Ulrich Drepper <drepper@redhat.com> * elf/dl-lookup.c: We don't need for specialized lookup functions. Combining the functionality does not slow down relocation processing, it might even speed it up a little. * sysdeps/generic/ldsodefs.h: Adjust prototypes for lookup function. Add only one function pointer to rtlf_global_ro. * elf/do-lookup.h: Replace #ifs with ifs. * elf/dl-libc.c: Adjust _dl_lookup_* callers. * elf/dl-reloc.c: Likewise. * elf/dl-runtime.c: Likewise. * elf/dl-sym.c: Likewise. * elf/rtld.c: Likewise. Adjust _rtld_global_ro initialization. * sysdeps/generic/ldsodefs.h (__rtld_local_attribute__, __rtld_global_attribute__): Undef after use. (_rtld_local_ro): Define __rtld_local_attribute__ with just hidden if available. * sysdeps/alpha/Subdirs: New file. * sysdeps/alpha/soft-fp/Makefile: New file. * sysdeps/alpha/soft-fp/Versions: New file. * sysdeps/alpha/soft-fp/local-soft-fp.h: New file. * sysdeps/alpha/soft-fp/ots_add.c: New file. * sysdeps/alpha/soft-fp/ots_cmp.c: new file. * sysdeps/alpha/soft-fp/ots_cmpe.c: New file. * sysdeps/alpha/soft-fp/ots_cvtqux.c: New file. * sysdeps/alpha/soft-fp/ots_cvtqx.c: New file. * sysdeps/alpha/soft-fp/ots_cvttx.c: New file. * sysdeps/alpha/soft-fp/ots_cvtxq.c: New file. * sysdeps/alpha/soft-fp/ots_cvtxt.c: New file. * sysdeps/alpha/soft-fp/ots_div.c: New file. * sysdeps/alpha/soft-fp/ots_mul.c: New file. * sysdeps/alpha/soft-fp/ots_nintxq.c: New file. * sysdeps/alpha/soft-fp/ots_sub.c: New file.
