Thu Aug 10 14:55:29 1995  Mike Stump  <mrs@cygnus.com>

	* except.c (expand_builtin_throw): Since we now use normal calling
	conventions for __throw, we have to remove the first layer off the

	memory when -Wall was used.
	(expand_end_all_catch, expand_leftover_cleanups,
	expand_end_catch_block, expand_throw): Change all uses of
	throw_label to match new style.

	different from throw_label.  Also, assume that our caller will wrap
	the passed label with a LABEL_REF, if needed.
	(expand_builtin_throw): Make external, change so that the generated
	throw is now a real function.
	(expand_exception_blocks): Never generate throw code inside another
	function.

Fri Aug  4 12:20:02 1995  Mike Stump  <mrs@cygnus.com>

	* decl.c (grokdeclarator): Move checking of mutable const objects

	handled correctly.
	(expand_start_all_catch): Instead of having many terminate protected
	regions, just have one.
	(expand_start_catch_block): No longer have to protect

	with one terminate region.

	pass unsaved SAVE_EXPRs to the backend.
	* tree.def (UNSAVE_EXPR): New tree code.
	* typeck.c (c_expand_return): Move goto/return code up inside
	conditional, as we don't always want to do this, we only want to do

	(xref_tag): xref_next_defn = ! globalize.

	synthesized methods.

	* class.c (finish_struct): Simplify.  We have to do rtti scanning at
	end, so we might as well do all of it there.

	* decl2.c (finish_vtable_vardecl): Now set the
	interface/implementation of vtables on the first virtual function,
	if one exists, otherwise we use the old method.  This is a major win
	in terms of cutting down the size of objects and executables in
	terms of text space and data space.  Now most of the savings that
	#pragma interface/implementation gives is automatic in a fair number
	of cases.

Sat Jan 28 04:57:33 1995  Jason Merrill  <jason@phydeaux.cygnus.com>

	* decl.c (grokdeclarator): Discard the template parameters in a
