From 9cf27b8d09aab26bd4693b10f281d64da779da83 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 5 Nov 2014 23:35:36 +0000 Subject: Remove INTDEF / INTUSE / INTVARDEF (bug 14132). Completing the removal of the obsolete INTDEF / INTUSE mechanism, this patch removes the final use - that for _dl_starting_up - replacing it by rtld_hidden_def / rtld_hidden_proto. Having removed the last use, the mechanism itself is also removed. Tested for x86_64 that installed stripped shared libraries are unchanged by the patch. (This is not much of a test since this variable is only defined and used in the !HAVE_INLINED_SYSCALLS case.) [BZ #14132] * include/libc-symbols.h (INTUSE): Remove macro. (INTDEF): Likewise. (INTVARDEF): Likewise. (_INTVARDEF): Likewise. (INTDEF2): Likewise. (INTVARDEF2): Likewise. * elf/rtld.c [!HAVE_INLINED_SYSCALLS] (_dl_starting_up): Use rtld_hidden_def instead of INTVARDEF. * sysdeps/generic/ldsodefs.h [IS_IN_rtld] (_dl_starting_up_internal): Remove declaration. (_dl_starting_up): Use rtld_hidden_proto. * elf/dl-init.c [!HAVE_INLINED_SYSCALLS] (_dl_starting_up): Remove declaration. [!HAVE_INLINED_SYSCALLS] (_dl_starting_up_internal): Likewise. (_dl_init) [!HAVE_INLINED_SYSCALLS]: Don't use INTUSE with _dl_starting_up. * elf/dl-writev.h (_dl_writev): Likewise. * sysdeps/powerpc/powerpc64/dl-machine.h [!HAVE_INLINED_SYSCALLS] (DL_STARTING_UP_DEF): Use __GI__dl_starting_up instead of _dl_starting_up_internal. --- elf/dl-init.c | 8 +------- elf/dl-writev.h | 2 +- elf/rtld.c | 4 ++-- 3 files changed, 4 insertions(+), 10 deletions(-) (limited to 'elf') diff --git a/elf/dl-init.c b/elf/dl-init.c index e5ade47acc..c80ec64a2f 100644 --- a/elf/dl-init.c +++ b/elf/dl-init.c @@ -23,12 +23,6 @@ /* Type of the initializer. */ typedef void (*init_t) (int, char **, char **); -#ifndef HAVE_INLINED_SYSCALLS -/* Flag, nonzero during startup phase. */ -extern int _dl_starting_up; -extern int _dl_starting_up_internal attribute_hidden; -#endif - static void call_init (struct link_map *l, int argc, char **argv, char **env) @@ -127,6 +121,6 @@ _dl_init (struct link_map *main_map, int argc, char **argv, char **env) #ifndef HAVE_INLINED_SYSCALLS /* Finished starting up. */ - INTUSE(_dl_starting_up) = 0; + _dl_starting_up = 0; #endif } diff --git a/elf/dl-writev.h b/elf/dl-writev.h index a5ce6c5166..6eace99ea5 100644 --- a/elf/dl-writev.h +++ b/elf/dl-writev.h @@ -42,7 +42,7 @@ _dl_writev (int fd, const struct iovec *iov, size_t niov) errno when it's being used by another thread that cares about it.
