Update.
2000-05-05 Ulrich Drepper <drepper@redhat.com> * 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 <jes@linuxcare.com> * 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 <jes@linuxcare.com> * 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 <jes@linuxcare.com> * 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 <jes@linuxcare.com> * 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.
