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.
