re PR tree-optimization/25528 (missed LIM on the tree level (complex types))
2006-01-06 Andrew Pinski <pinskia@physics.uc.edu>
PR tree-opt/25528
* tree-ssa-alias.c (find_used_portions): Handle REALPART_EXPR
and IMAGPART_EXPR.
* tree-flow-inline.h (var_can_have_subvars): Handle complex types
on non gimple variables. Also add checks at the top for decls and
mtags.
* tree-ssa-structalias.c (push_fields_onto_fieldstack): Handle
complex types.
* tree-ssa-operands.c (parse_ssa_operands): Handle REALPART_EXPR
and IMAGPART_EXPR for creating MUST_DEFs.
(get_expr_operands): Handle SSA_NAME, STRUCT_FIELD_TAG, TYPE_MEMORY_TAG,
and NAME_MEMORY_TAG separately from the DECLs.
