Update.

2001-08-26  Jakub Jelinek  <jakub@redhat.com>

	* elf/dl-reloc.c (RESOLVE_MAP, RESOLVE): Use elf_machine_type_class
	instead of elf_machine_lookup_noexec_p and elf_machine_lookup_noplt_p.
	Pass type_class to _dl_lookup_*.
	* elf/dl-lookup.c (_dl_lookup_symbol): Take type_clas parameter now.
	Pass around just type_class instead of noexec, noplt pair.
	(_dl_lookup_versioned_symbol): Likewise.
	(_dl_lookup_symbol_skip): Pass around just type_class instead of
	noexec, noplt pair.
	(_dl_lookup_versioned_symbol_skip): Likewise.
	(_dl_do_lookup, _dl_do_lookup_versioned): Likewise.
	* elf/do-lookup.h (do_lookup): Likewise.
	* include/link.h (struct link_map): Replace noexec and noplt fields
	in l_lookup_cache with type_class field.
	* sysdeps/generic/ldsodefs.h (ELF_RTYPE_CLASS_PLT,
	ELF_RTYPE_CLASS_COPY): Define.
	Adjust prototypes for _dl_lookup_symbol and
	_dl_lookup_versioned_symbol.
	* sysdeps/alpha/dl-machine.h (elf_machine_lookup_noplt_p,
	elf_machine_lookup_noexec_p): Remove.
	(elf_machine_type_class): Define.
	* sysdeps/arm/dl-machine.h: Likewise.
