re PR tree-optimization/20458 (structure aliasing causes wrong code)
2005-03-14 Daniel Berlin <dberlin@dberlin.org>
Fix PR tree-optimization/20458
* tree-flow-inline.h (mark_call_clobbered): Don't fiddle
DECL_EXTERNAL on STRUCT_FIELD tags.
(clear_call_clobbered): Ditto.
* tree-ssa-operands.c (note_addressable): Make sure the original
variable doesn't slip into the addressable list if we have
subvars.
* tree-tailcall.c (suitable_for_tail_opt_p): Look at STRUCT_FIELD
tags too.
