From c08bc50a60a92e8d32f302ea411312bc438f05ef Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 26 Feb 2001 17:53:15 +0000 Subject: Update. 2001-02-26 Ulrich Drepper * dlfcn/Makefile (distribute): Add modatexit.c and modcxaatexit.c. (tests): Add tstatexit and tstcxaatexit. (module-names): Add modatexit and modcxaatexit. Add rules to build and run tstatexit and tstcxaatexit. * dlfcn/modatexit.c: New file. * dlfcn/modcxaatexit.c: New file. * dlfcn/tstatexit.c: New file. * dlfcn/tstcxaatexit.c: New file. * io/Makefile: Pass -DHAVE_DOT_HIDDEN to stat and mknod functions if .hidden is available. * io/stat.c: If .hidden is available use it to avoid exporting functions. * io/fstat.c: Likewise. * io/lstat.c: Likewise. * io/stat64.c: Likewise. * io/fstat64.c: Likewise. * io/lstat64.c: Likewise. * sysdeps/generic/mknod.c: Likewise. * malloc/mtrace.c: Use __cxa_atexit and not atexit. * sysdeps/generic/bb_init_func.c: Likewise. * sysdeps/generic/libc-start.c: Likewise. * stdlib/atexit.c (__new_exitfn): Move to cxa_atexit.c. (atexit): Implement using __cxa_atexit. Use .hidden if availble to avoid exporting atexit. * stdlib/cxa_atexit.c (__new_exitfn): Moved to here from atexit.c. * stdlib/Versions: Export __new_exitfn for GLIBC_2.2.3. * stdlib/Makefile (routines): Add old_atexit. (static-only-routines): Add atexit. Pass -DHAVE_DOT_HIDDEN for atexit.c if .hidden is available. * stdlib/old_atexit.c: New file. * intl/Makefile: Remove bogus endif. --- io/Makefile | 10 ++++++++++ io/fstat.c | 9 ++++++++- io/fstat64.c | 8 +++++++- io/lstat.c | 9 ++++++++- io/lstat64.c | 8 +++++++- io/stat.c | 9 ++++++++- io/stat64.c | 8 +++++++- 7 files changed, 55 insertions(+), 6 deletions(-) (limited to 'io') diff --git a/io/Makefile b/io/Makefile index f68b12d2a1..d102eecbef 100644 --- a/io/Makefile +++ b/io/Makefile @@ -66,6 +66,16 @@ CFLAGS-fts.c = -Wno-uninitialized CFLAGS-test-stat.c = -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE CFLAGS-test-lfs.c = -D_LARGEFILE64_SOURCE +ifeq (yes,$(have-protected)) +CFLAGS-stat.c = -DHAVE_DOT_HIDDEN +CFLAGS-fstat.c = -DHAVE_DOT_HIDDEN +CFLAGS-lstat.c = -DHAVE_DOT_HIDDEN +CFLAGS-mknod.c = -DHAVE_DOT_HIDDEN +CFLAGS-stat64.c = -DHAVE_DOT_HIDDEN +CFLAGS-fstat64.c = -DHAVE_DOT_HIDDEN +CFLAGS-lstat64.c = -DHAVE_DOT_HIDDEN +endif + test-stat2-ARGS = Makefile . $(objpfx)test-stat2 ifeq ($(cross-compiling),no) diff --git a/io/fstat.c b/io/fstat.c index d93d0929ac..bd68b94461 100644 --- a/io/fstat.c +++ b/io/fstat.c @@ -1,4 +1,4 @@ -/* Copyright (C) 1996, 1997, 1998 Free Software Foundation, Inc. +/* Copyright (C) 1996, 1997, 1998, 2001 Free Software Foundation, Inc.
