	From Jim Blandy  <jimb@redhat.com>:

	Use a single, consistent representation for an empty minimal
	symbol table in an objfile.
	* objfiles.c (terminate_minimal_symbol_table): New function.
	(allocate_objfile): Call it.
	* objfiles.h (terminate_minimal_symbol_table): New declaration.
	(ALL_MSYMBOLS): No need to test whether (objfile)->msymbols is
	non-NULL.
	* minsyms.c (lookup_minimal_symbol_by_pc_section): To see whether
	objfile has minimal symbols, compare minimal_symbol_count to zero,
	instead of comparing msymbols with NULL.
	* objfiles.c (have_minimal_symbols): Same.
	* solib-sunos.c (solib_add_common_symbols): Call
	terminate_minimal_symbol_table.
	* symfile.c (reread_symbols): Same.

	* objfiles.h: Revert patch from 2003-01-27, to be replaced by
	similar patch from Jim Blandy.
	* objfiles.c (objfile_relocate): Ditto.
	* i386-linux-tdep.c (find_minsym_and_objfile): Ditto.
	* arm-linux-tdep.c (find_minsym_and_objfile): Ditto.
	* gdbtypes.h: Delete INTEGER_COERCION_BADNESS,
	FLOAT_COERCION_BADNESS.
	* gdbtypes.c (rank_one_type): Replace all uses of
	INTEGER_COERCION_BADNESS by INTEGER_CONVERSION_BADNESS.
	* valops.c (find_overload_match): Call cp_func_name.
	* cp-support.h: Declare cp_func_name.
	* cp-support.c (cp_func_name): New function.

2003-01-30  David Carlton  <carlton@math.stanford.edu>

	* valops.c (find_overload_match): Move code into
	find_oload_champ_namespace.
	(find_oload_champ_namespace): New function, which immediately gets
	eviscerated and turned into a call to
	find_oload_champ_namespace_loop.
	(find_oload_champ_namespace_loop): New function.
	* symtab.c (make_symbol_overload_list): Move entire body into
	make_symbol_overload_list_qualified.
	(make_symbol_overload_list_qualified): New.
	(read_in_psymtabs): New.
	(make_symbol_overload_list_qualified): Rewrite.
	(make_symbol_overload_list_using): New.
	(lookup_symbol_namespace): Use alloca, not xmalloc.
	(make_symbol_overload_list): Put some memory management stuff back
	in.
