Update.
* elf/rtld.c: Add a few __builtin_expects where they will improve a lot. 1998-11-05 Ulrich Drepper <drepper@cygnus.com> 1998-11-04 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * libio/genops.c (_IO_least_marker): Add additional parameter end_p replacing fp->_IO_read_end. (save_for_backup): Likewise. All callers changed. Use _IO_size_t and _IO_ssize_t instead of int. (_IO_switch_to_main_get_area): Remove use of _IO_save_ptr. (_IO_switch_to_backup_area): Likewise. Fix comments. (_IO_seekmark): Undo last change. (_IO_default_pbackfail): Correct use of backup area. * libio/libio.h (_IO_FILE_complete): Remove _IO_save_ptr.
