From 463468350f1735034d9f1b4a3d4a50a5a794620e Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 22 Apr 2001 03:33:47 +0000 Subject: Update. 2001-04-21 Franz Sirl * sysdeps/unix/sysv/linux/powerpc/mmap64.c: Correct check for invalid offset. 2001-04-21 Ulrich Drepper * posix/getopt.h: Treat __cplusplus like __STDC__. 2001-04-20 John S. Marvin * sysdeps/unix/sysv/linux/hppa/clone.S: Fix clone system call entry point stub. 2001-04-20 Richard Hirst * elf/elf.h: Corrected R_PARISC_DIR14R (should be 6, not 5), and added R_PARISC_DPREL21L and R_PARISC_DPREL14R for modutils. * sysdeps/unix/sysv/linux/hppa/syscalls.list: Removed ptrace entry so the ptrace.c wrapper is used. 2001-04-20 Alan Modra * sysdeps/hppa/dl-lookupcfg.h (_dl_function_address): Prototype. (DL_FUNCTION_ADDRESS): Define. (DL_DT_INIT_ADDRESS): Define. (DL_DT_FINI_ADDRESS): Define. * sysdeps/hppa/Versions: Add _dl_function_address. * sysdeps/hppa/dl-machine.h (ELF_MACHINE_START_ADDRESS): Define. * sysdeps/hppa/dl-symaddr.c (_dl_start_address): Rename to _dl_function_address. --- sysdeps/hppa/Versions | 1 + sysdeps/hppa/dl-lookupcfg.h | 13 +++++++++++++ sysdeps/hppa/dl-machine.h | 4 ++++ sysdeps/hppa/dl-symaddr.c | 2 +- sysdeps/unix/sysv/linux/hppa/clone.S | 14 +++++++------- sysdeps/unix/sysv/linux/hppa/syscalls.list | 2 -- sysdeps/unix/sysv/linux/powerpc/mmap64.c | 2 +- 7 files changed, 27 insertions(+), 11 deletions(-) (limited to 'sysdeps') diff --git a/sysdeps/hppa/Versions b/sysdeps/hppa/Versions index 0c447d9..c5f35d4 100644 --- a/sysdeps/hppa/Versions +++ b/sysdeps/hppa/Versions @@ -2,5 +2,6 @@ ld { GLIBC_2.2 { # hppa specific functions in the dynamic linker, but used by libc.so. _dl_symbol_address; _dl_unmap; _dl_lookup_address; + _dl_function_address; } } diff --git a/sysdeps/hppa/dl-lookupcfg.h b/sysdeps/hppa/dl-lookupcfg.h index 4f5f899..118c4d0 100644 --- a/sysdeps/hppa/dl-lookupcfg.h +++ b/sysdeps/hppa/dl-lookupcfg.h @@ -34,3 +34,16 @@ Elf32_Addr _dl_lookup_address (const void *address); void _dl_unmap (struct link_map *map); #define DL_UNMAP(map) _dl_unmap (map) + +extern Elf32_Addr _dl_function_address (const struct link_map *map, + Elf32_Addr start); + +#define DL_FUNCTION_ADDRESS(map, addr) _dl_function_address (map, addr) + +/* The test for "addr & 2" below is to accomodate old binaries which + violated the ELF ABI by pointing DT_INIT and DT_FINI at a function + pointer. */ +#define DL_DT_INIT_ADDRESS(map, addr) \ + ((Elf32_Addr)(addr) & 2 ?
