From 20792f9946b2ef0c9e6b75f4243d4404850ecd38 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 30 Apr 2003 04:18:12 +0000 Subject: * configure.in: Search for AUTOCONF unconditionally. Just don't complain about missing it under --without-cvs. * configure: Regenerated. * include/libc-symbols.h (__symbol_set_attribute): New macro, give hidden for [SHARED] and weak for [! SHARED]. (symbol_set_declare): Use that. Never need weak_extern these days. * Makerules ($(common-objpfx)shlib.lds): Go back to using PROVIDE. Depend on $(..)Makerules. --- include/libc-symbols.h | 15 +++++++++++---- 1 file changed, 11 insertions(+), 4 deletions(-) (limited to 'include/libc-symbols.h') diff --git a/include/libc-symbols.h b/include/libc-symbols.h index c4bd028..79add73 100644 --- a/include/libc-symbols.h +++ b/include/libc-symbols.h @@ -345,11 +345,18 @@ be able to use the set's contents. */ # define symbol_set_define(set) symbol_set_declare(set) -/* Declare SET for use in this module, if defined in another module. */ +/* Declare SET for use in this module, if defined in another module. + In a shared library, this is always local to that shared object. + For static linking, the set might be wholly absent and so we use + weak references. */ # define symbol_set_declare(set) \ - extern void *const __start_##set __attribute__ ((__weak__)); \ - extern void *const __stop_##set __attribute__ ((__weak__)); \ - weak_extern (__start_##set) weak_extern (__stop_##set) + extern void *const __start_##set __symbol_set_attribute; \ + extern void *const __stop_##set __symbol_set_attribute; +# ifdef SHARED +# define __symbol_set_attribute attribute_hidden +# else +# define __symbol_set_attribute __attribute__ ((weak)) +# endif /* Return a pointer (void *const *) to the first element of SET. */ # define symbol_set_first_element(set) (&__start_##set) -- cgit v1.1
