From c0282c0642e99b375ab14fd343aa537445cd72a4 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 5 May 2000 07:15:29 +0000 Subject: Update. 2000-05-05 Ulrich Drepper * elf/dl-load.c (_dl_map_object_from_fd): Little of computation of parameter to mprotect and for variable assignments. 2000-05-03 Jes Sorensen * sysdeps/generic/ldsodefs.h (LOOKUP_VALUE_ADDRESS): Check the validity of map before dereferencing it. * elf/dl-reloc.c (RESOLVE_MAP): Define. 2000-05-02 Jes Sorensen * elf/dl-runtime.c (fixup): Add the value returned in the symbol lookup to the arguments to elf_machine_fixup_plt(). * sysdeps/ia64/dl-machine.h (elf_machine_fixup_plt): Add Link_map of the symbol being resolved to input argument list and make the function return the pointer to the reloc. * sysdeps/alpha/dl-machine.h (elf_machine_fixup_plt): Change return valuie to lookup_t and return the value. * sysdeps/arm/dl-machine.h (elf_machine_fixup_plt): Likewise. * sysdeps/generic/dl-machine.h (elf_machine_fixup_plt): Likewise. * sysdeps/i386/dl-machine.h (elf_machine_fixup_plt): Likewise. * sysdeps/m68k/dl-machine.h (elf_machine_fixup_plt): Likewise. * sysdeps/sparc/sparc32/dl-machine.h (elf_machine_fixup_plt): Likewise. * sysdeps/sparc/sparc64/dl-machine.h (elf_machine_fixup_plt): Likewise. * sysdeps/powerpc/dl-machine.h (elf_machine_fixup_plt): Likewise. Make it an inline function returning value after calling __elf_machine_fixup_plt(). * elf/dl-sym.c (_dl_vsym): Use DL_SYMBOL_ADDRESS() to obtain the symbol address. * elf/dl-symbol.c (_dl_symbol_value): Use LOOKUP_VALUE_ADDRESS to obtain the symbol address. * sysdeps/generic/ldsodefs.h: Add generic DL_SYMBOL_ADDRESS() macro depending on the definition of ELF_FUNCTION_PTR_IS_SPECIAL. * sysdeps/ia64/dl-machine.h: Add DL_SYMBOL_ADDRESS() macro calling _dl_symbol_address() - this way DL_SYMBOL_ADDRESS() turns into an inline on non ia64. 2000-04-28 Jes Sorensen * elf/dl-runtime.c (fixup): Use the portable macros to get the symbol address of an object. * elf/dl-runtime.c (fixup-profile): Use the portable macros to get the symbol address of an object. * elf/dl-libc.c (struct do_dlsym_args): Change loadbase to a lookup_t. * elf/dl-lookup.c (_dl_lookup_symbol): Likewise. (_dl_lookup_symbol_skip): Likewise. (_dl_lookup_versioned_symbol): Likewise. (_dl_lookup_versioned_symbol_skip): Likewise. 2000-04-27 Jes Sorensen * elf/rtld.c (_dl_start): Get the function pointer return address via _dl_start_address for architectures that need a function pointer descriptor rather than just a pointer (ia64). * sysdeps/generic/dl-lookupcfg.h: New file. * sysdeps/ia64/dl-lookupcfg.h: New file. * sysdeps/ia64/dl-machine.h: New file. * sysdeps/ia64/dl-symaddr.c: New file. * sysdeps/ia64/dl-fptr.c: New file. * elf/elf.h: Add IA-64 specific definitions. --- elf/dl-lookup.c | 18 +++++++++--------- 1 file changed, 9 insertions(+), 9 deletions(-) (limited to 'elf/dl-lookup.c') diff --git a/elf/dl-lookup.c b/elf/dl-lookup.c index dc4564f..c38e2e8 100644 --- a/elf/dl-lookup.c +++ b/elf/dl-lookup.c @@ -86,7 +86,7 @@ static int add_dependency (struct link_map *undef_map, struct link_map *map) { struct link_map **list; - unsigned act; + unsigned int act; unsigned int i; int result = 0; @@ -183,7 +183,7 @@ add_dependency (struct link_map *undef_map, struct link_map *map) /* Search loaded objects' symbol tables for a definition of the symbol UNDEF_NAME. */ -ElfW(Addr) +lookup_t internal_function _dl_lookup_symbol (const char *undef_name, struct link_map *undef_map, const ElfW(Sym) **ref, struct r_scope_elem *symbol_scope[], @@ -241,7 +241,7 @@ _dl_lookup_symbol (const char *undef_name, struct link_map *undef_map, ": symbol `", undef_name, "'\n", NULL); *ref = current_value.s; - return current_value.m->l_addr; + return LOOKUP_VALUE (current_value.m); } @@ -250,7 +250,7 @@ _dl_lookup_symbol (const char *undef_name, struct link_map *undef_map, it only considers objects which were loaded after the described object.
