The regression reported in PR c++/9165 showed up starting
with this patch:
2002-10-11 Mark Mitchell <mark@codesourcery.com>
* NEWS: Document removal of "new X = ..." extension.
* class.c (initialize_array): Set TREE_HAS_CONSTRUCTOR on
brace-enclosed initializers.
* cp-tree.h (CP_AGGREGATE_TYPE_P): New macro.
(initialize_local_var): Remove declaration.
(expand_static_init): Likewise.
* decl.c (next_initializable_field): New function.
(reshape_init): Likewise.
(check_initializer): Use them. Build dynamic initializer for
aggregates here too.
(initialize_local_var): Simplify, and incorporate cleanup
insertion code as well.
(destroy_local_var): Remove.
(cp_finish_decl): Tidy.
(expand_static_init): Fold checks for whether or not a variable
needs initialization into this function. Simplify.
* decl2.c (do_static_initialization): Simplify.
* init.c (build_init): Do not set TREE_SIDE_EFFECTS when it will
be done for us automatically.
(expand_default_init): Handle brace-enclosed initializers
correctly.
(expand_aggr_init_1): Remove RTL-generation code.
(build_vec_init): Remove "new X = ..." support.
* parse.y (new_initializer): Likewise.
* rtti.c (get_pseudo_ti_init): Set TREE_HAS_CONSTRUCTOR on
brace-enclosed initializer.
(create_pseudo_type_info): Likewise.
* typeck2.c (store_init_value): Don't try to handle digest_init
being called more than once.
(digest_init): Tidy handling of brace-enclosed initializers.
Here's the test case from the PR:
-------------------
// false "defined but not used" warnings; regression from 3.2.1
// compile with -O -Wall; should get no warnings
void do_cleanups();
class Cleanup {
public:
~Cleanup() { do_cleanups();}
};
static Cleanup dummy;
-------------------
Output from the compiler:
9165.C:11: warning: `Cleanup dummy' defined but not used
I've added this information to the PR.
