tree-flow.h (struct fieldoff): Decompose field to type, size and decl.
2006-01-05 Richard Guenther <rguenther@suse.de>
* tree-flow.h (struct fieldoff): Decompose field to
type, size and decl.
* tree-ssa-alias.c (create_sft): Take type as parameter.
(create_overlap_variables_for): Store type, size and decl
in the fieldoff structure.
* tree-ssa-structalias.c (fieldoff_compare): Adjust users
of struct fieldoff.
(push_fields_onto_fieldstack): Likewise.
(create_variable_info_for): Likewise. Use offset for the
SFT name if the decl is not available.
