Wed Sep 11 22:38:13 1996 Gerald Baumgartner <gb@cs.purdue.edu>
* call.c (build_method_call): When calling a signature
default implementation, as in other cases, let instance_ptr simply
be instance.
Wed Sep 11 22:14:44 1996 Mike Stump <mrs@cygnus.com>
* parse.y (simple_stmt): Cleanup and use do_poplevel ().
Wed Sep 11 22:10:48 1996 Mike Stump <mrs@cygnus.com>
* except.c (expand_start_catch_block): Add a pushlevel so that -g
works on hppa and SPARC.
Wed Sep 11 10:18:06 1996 Brendan Kehoe <brendan@lisa.cygnus.com>
* typeck.c (build_indirect_ref): Catch PTR being an error_mark_node.
Mon Sep 9 19:51:14 1996 Gerald Baumgartner <gb@cs.purdue.edu>
* call.c (build_over_call): Check first whether DECL_CONTEXT exists
before testing whether it's a signature.
Sun Sep 8 16:06:57 1996 Gerald Baumgartner <gb@cs.purdue.edu>
* call.c (build_new_method_call): Don't complain about signature
pointers and references not being an aggr type.
(build_this): If a signature pointer or reference was passed in,
just return it.
(build_new_method_call): If instance is a signature pointer, set
basetype to the signature type of instance.
* sig.c (build_signature_method_call): Deleted basetype and
instance parameters, they can be found as the DECL_CONTEXT of
function and as the first argument passed in.

of build_signature_method_call.
