re PR c++/33407 (C++ operator new and new expression do not change dynamic type)
PR c++/33407
./: * tree.h (DECL_IS_OPERATOR_NEW): Define.
(struct tree_function_decl): Add new field operator_new_flag.
* tree-inline.c (expand_call_inline): When inlining a call to
operator new, force the return value to go into a variable, and
set DECL_NO_TBAA_P on that variable.
* c-decl.c (merge_decls): Merge DECL_IS_OPERATOR_NEW flag.
cp/:
* decl.c (duplicate_decls): Copy DECL_IS_OPERATOR_NEW flag.
(grok_op_properties): For NEW_EXPR and VEC_NEW_EXPR set
DECL_IS_OPERATOR_NEW flag.
testsuite/:
* g++.dg/init/new26.C: New test.
