2004-11-09  Andrew Pinski  <pinskia@physics.uc.edu>

	PR objc/18406
	* obj-act.c (encode_type): 96bits doubles are encoded the
	same way as 64bit and 128bit doubles are.

	* objc-act.c: Use %q, %< and %> for quoting in diagnostics.

2004-11-08  Andrew Pinski  <pinskia@physics.uc.edu>

	PR objc/16546
	* objc-act.c (generate_method_descriptors): Remove setting
	the new decls' type to variable_length_type.
	(generate_ivar_lists): Likewise.
	(generate_dispatch_tables): Likewise.

2004-10-30  Ziemowit Laski  <zlaski@apple.com>

	* objc-act.c (objc_lookup_ivar): The new OTHER parameter
	contains the result of the ID lookup by the C or C++
	front-end; in class methods, use OTHER if it exists;
	in instance methods, use OTHER only if it is locally
	declared.

	throughout.
