From 40306912c9451bdebb5850c97c4d6bf25bfc83cb Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 16 Nov 2000 18:15:26 +0000 Subject: Update. 2000-11-15 H.J. Lu * sysdeps/generic/ldsodefs.h (DL_DT_INIT_ADDRESS): Defined if ELF_FUNCTION_PTR_IS_SPECIAL is not defined. (DL_DT_FINI_ADDRESS): Likewise. * sysdeps/ia64/dl-lookupcfg.h (_dl_lookup_address): Set the return type to ElfW(Addr). (_dl_function_address): New prototype. (DL_FUNCTION_ADDRESS): Defined. (DL_DT_INIT_ADDRESS): Defined as DL_FUNCTION_ADDRESS. (DL_DT_FINI_ADDRESS): Likewise. * sysdeps/ia64/Versions (GLIBC_2.2): Add _dl_function_address. * sysdeps/ia64/dl-machine.h (_dl_start_address): Removed. (ELF_MACHINE_START_ADDRESS): Changed to DL_FUNCTION_ADDRESS. * sysdeps/ia64/dl-symaddr.c (_dl_start_address): Renamed to ... (_dl_function_address): This. * elf/dl-fini.c (_dl_fini): Use DL_DT_FINI_ADDRESS to get the function pointer for DT_FINI. * elf/dl-close.c (_dl_close): Likewise. * elf/dl-init.c (_dl_init): Use DL_DT_INIT_ADDRESS to get the function pointer for DT_INIT. 2000-11-16 Jakub Jelinek * sysdeps/generic/printf_fphex.c (__printf_fphex): Compute correctly end of wexpbuf buffer. --- ChangeLog | 33 +++++++++++++++++++++++++++++++++ elf/dl-close.c | 5 +++-- elf/dl-fini.c | 2 +- elf/dl-init.c | 3 ++- sysdeps/generic/ldsodefs.h | 2 ++ sysdeps/ia64/Versions | 1 + sysdeps/ia64/dl-lookupcfg.h | 14 +++++++++++--- sysdeps/ia64/dl-machine.h | 7 ++----- sysdeps/ia64/dl-symaddr.c | 6 +++--- 9 files changed, 58 insertions(+), 15 deletions(-) diff --git a/ChangeLog b/ChangeLog index 372b4ec32d..128a11d60a 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,36 @@ +2000-11-15 H.J.
