* trans.c (mark_visited): Set TYPE_SIZES_GIMPLIFIED.
2004-12-22 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
* tree.h (TYPE_SIZES_GIMPLIFIED): New.
* function.c (gimplify_parm_type): Don't gimplify type if already done.
* gimplify.c (gimplify_decl_expr): Likewise.
(gimplify_type_sizes): Set TYPE_SIZES_GIMPLIFIED. Examine nested
array types.

* gimplify.c (eval_save_expr): Remove.
(gimplify_one_sizepos): Unshare expr before gimplifying.
* stor-layout.c (variable_size): Revert 2004-12-19 change.
(layout_decl): Revert 2004-12-18 change.
