I believe this all are fixed by:
2004-01-26 Mark Mitchell <mark@codesourcery.com>
* class.c (add_method): Just check processing_template_decl to
determine whether or not we are within a template.
* decl2.c (maybe_retrofit_in_chrg): Likewise.
* init.c (decl_constant_value): Check the type of the declaration,
not TREE_READONLY.
* name-lookup.c (maybe_push_to_top_level): Rename to ...
(push_to_top_level): ... this.
* name-lookup.h (maybe_push_to_top_level): Do not declare it.
* pt.c (push_template_decl_real): Reorder condition for speed.
(convert_template_argument): Use dependency-checking functions in
place of uses_template_parms.
(lookup_template_class): Avoid calling uses_template_parms more
than once.
(uses_template_parms): Reimplement, using dependency-checking
functions.
(instantiate_class_template): Use push_to_top_level, not
maybe_push_to_top_level.
(type_unification_real): Simplify.
(type_dependent_expression_p): Handle OFFSET_REFs and
TEMPLATE_DECLs.
(any_dependent_template_arguments_p): Handle multiple levels of
template argument.
* semantics.c (expand_or_defer_fn): Do not check
uses_template_parms for template instantiations.
* typeck.c (comptypes): Avoid calling cp_type_quals.

Have you tried it, or should I do it myself as a bug reporter?

I have not tried yet because I do not have a 3.3.2. As I should have said the patch which I pointed
out is ment to speed up C++. Could you try as the reporter?

I have retested with the recent tree and results are provided here:
http://gcc.gnu.org/ml/gcc/2004-01/msg02173.html
The overall impression is very good, but still some interesting regressions are
presented.

Okay so -O0 is no longer a regression which means that it is only the optimizers which. Thanks
for testing.

Can you please do a -ftime-report? If the time is spent in combine, then this
is a duplicate of PR13931.

I've just tried compiling the indicated typecode.cc.ii with -O2 -ftime-report
on i686-pc-cygwin (3.5.0 20040131), and get very different numbers:
garbage collection : 3.80 (10%) usr 0.00 ( 0%) sys 3.80 ( 9%) wall
life analysis : 13.26 (34%) usr 0.03 ( 2%) sys 13.33 (33%) wall

expand : 1.37 ( 4%) usr 0.01 ( 1%) sys 1.39 ( 3%) wall
CSE : 1.70 ( 4%) usr 0.00 ( 0%) sys 1.70 ( 4%) wall
global alloc : 3.03 ( 8%) usr 0.02 ( 1%) sys 3.06 ( 8%) wall
TOTAL : 38.64 1.50 40.30
I'll try on x86/Linux, but if RTL expansion is a problem, its target dependent.
