* 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.
