From bff334e09023c8cf6327e9ff87b117f2331330d2 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 22 Jun 2002 05:24:45 +0000 Subject: Update. 2002-06-17 Jakub Jelinek * elf/dl-lookup.c (_dl_debug_bindings): Use type_class 4 for TLS lookups. * elf/rtld.c (dl_main): Move TLS setup code before LD_TRACE_PRELINKING code. Print TLS modid and offset for modules containing PT_TLS segments. 2002-06-09 Jakub Jelinek * sysdeps/unix/sysv/linux/i386/dl-brk.c: Move... * sysdeps/unix/sysv/linux/dl-brk.c: ...here. * sysdeps/unix/sysv/linux/i386/dl-sbrk.c: Move... * sysdeps/unix/sysv/linux/dl-sbrk.c: ...here. 2002-06-07 Jakub Jelinek * nss/getXXbyYY_r.c (NEW, NEW1): Define. (NEW (REENTRANT_NAME)): Strong alias to INTERNAL (REENTRANT_NAME). (REENTRANT_NAME@@GLIBC_2.1.2): Use NEW (REENTRANT_NAME). * nss/getXXent_r.c (NEW, NEW1): Define. (NEW (REENTRANT_GETNAME)): Strong alias to INTERNAL (REENTRANT_GETNAME). (REENTRANT_GETNAME@@GLIBC_2.1.2): Use NEW (REENTRANT_GETNAME). 2002-06-21 Ulrich Drepper * libio/fileops.c (_IO_file_setbuf_mmap): New function. (_IO_file_jumps_mmap): Use it. * libio/iosetvbuf.c: Don't call _IO_WSETBUF. * libio/libioP.h: Remove _IO_wdefault_setbuf and _IO_wdefault_setbuf_internal prorotypes. Add _IO_file_setbuf_mmap prototype. * libio/wfileops.c (_IO_wfile_setbuf): Removed. (_IO_wfile_jumps_mmap): Don't use it anymore. * libio/wgenops.c (_IO_wdefault_setbuf): Removed. * libio/memstream.c (_IO_wmem_jumps): Use _IO_default_setbuf not _IO_wdefault_setbuf. * libio/vswprintf.c (_IO_wstrn_jumps): Likewise. * libio/wstrops.c (_IO_wstr_jumps): Likewise. * stdio-common/vfprintf.c (_IO_helper_jumps): Likewise. 2002-06-05 Jakub Jelinek * libio/Makefile (tests): Add tst-mmap-setvbuf. * libio/tst-mmap-setvbuf.c: New test. --- libio/tst-mmap-setvbuf.c | 82 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 82 insertions(+) create mode 100644 libio/tst-mmap-setvbuf.c (limited to 'libio/tst-mmap-setvbuf.c') diff --git a/libio/tst-mmap-setvbuf.c b/libio/tst-mmap-setvbuf.c new file mode 100644 index 0000000000..6fe9ce3482 --- /dev/null +++ b/libio/tst-mmap-setvbuf.c @@ -0,0 +1,82 @@ +/* Test setvbuf on readonly fopen (using mmap stdio). + Copyright (C) 2002 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Jakub Jelinek , 2002. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
