From 9a821cf90b38590fa546dc3246d12526e4f95ba1 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 5 Nov 1998 17:52:04 +0000 Subject: [PATCH] Update. * elf/rtld.c: Add a few __builtin_expects where they will improve a lot. 1998-11-05 Ulrich Drepper 1998-11-04 Andreas Schwab * 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. --- ChangeLog | 17 +++++++++++++++++ README | 4 ++-- elf/rtld.c | 12 ++++++------ manual/install.texi | 1 + 4 files changed, 26 insertions(+), 8 deletions(-) diff --git a/ChangeLog b/ChangeLog index c8e6a234d4..f41a7d1686 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,8 @@ +1998-11-05 Ulrich Drepper + + * elf/rtld.c: Add a few __builtin_expects where they will improve + a lot. + 1998-11-05 Ulrich Drepper * version.h (VERSION): Bump to 2.0.100. @@ -7,6 +12,18 @@ * sysdeps/libm-i387/s_fma.S: Optimize a bit. * sysdeps/libm-i387/s_fmaf.S: Likewise. +1998-11-04 Andreas Schwab + + * libio/genops.c (_IO_least_marker): Add additional parameter + end_p replacing fp->_IO_read_end. + (save_for_backup): Likewise.
