Subject: [RFA] Delayed physname computation
Hi,
This is actually a patch for symtab/11465.
Basically, dwarf2_physname is constructing the name of a class method in
which one of the method's parameters is of a type that has not yet been
fully processed. (c_type_print_args will say "<incomplete type>"). Bad
things happen in/under c_type_print_args when you give it an incomplete
type like this.
The solution I've implemented is to simply delay processing of method
physnames until the entire CU has been read/processed.
Unfortunately, this is another example in which the compiler used may
alter the test outcome. As a result, I've had to hack in a test case
which is independent of the compiler. I would appreciate special
attention to the test source file (pr11465.S), which is an edited
version of gcc's --save-temps output.
I have regression tested this on x86 and x86_64 linux. There aer no
regressions, and the new test now passes.

ChangeLog
2010-04-20 Keith Seitz <keiths@redhat.com>
* dwarf2read.c (struct delayed_method_info): New struct.
(struct dwarf2_cu): Add members method_index and method_list.
(struct dwarf2_per_cu_data): Add member num_methods.
(count_partial_methods): New function.
(scan_partial_symbols): Count methods for union, class, structure,
and interface types.
(add_partial_subprogram): Count methods here, too.
(add_to_method_list): New function.
(compute_delayed_physnames): New function.
(process_full_comp_unit): Allocate the CU's methods list,
compute delayed physnames, and free the method list.
(dwarf2_add_member_fn): For C++ and Java, delay the computation
of the physname until after the CU is read.
(load_partial_dies): Add subprogram and lexical block DIEs
for Java and C++, too.
