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.
