This is a clean-up of some of our symbol-lookup machinery to pull some
kludgy Ada-specific definitions out of psymtab.c. In place of
map_ada_symtabs and ada_lookup_partial_symbol, we have a method
map_matching_symbols, which searches through all symbol tables and
partial symbol tables looking for a symbol that matches according to
a matching function that is passed as a parameter. This requires some
care, because partial symbol tables speed up searches by binary search,
while full symbol tables use hashing. To call map_matching_symbols, therefore,
you may need to supply both a matching function that is compatible with the
dictionary hash function and an ordering relation that is compatible with
strcmp_iw, which is used to order partial symbol tables.
Having added this general routine to psymtab.c, we use it in ada-lang.c
to rework add_non_local_symbols (now renamed add_nonlocal_symbols).

According to the DWARF3 standard, a function always has a name attribute
(Section 3.3 - Subroutine and Entry Point Entries). The only exception
is when a DW_AT_abstract_origin attribute is provided, in which case
the name may be inherited from the referenced DIE.
The problem occured because our compiler generated a subprogram DIE
for a nested function where the name attribute was missing (and no
abstract-origin either). Our code in add_partial_symbol is not
prepared to deal with the situation, and happily just tries to compute
the length of the (NULL) function name.
This normally cannot happen, because there is already a guard in
scan_partial_symbols, where we (silently!) ignore anonymous dies,
including anonymous subprograms. Unfortunately, there is a flaw that
affects Ada and other languages that allow nested subprograms. For
nested subprograms, we do not go through scan_partial_symbols and
thus we are missing the name check.
This patch adds the name check in the nested subprogram case. It also
adds a complaint which is emitted during the psymtab->symtab conversion
phase.
gdb/ChangeLog:
* dwarf2read.c (add_partial_subprogram): Make sure the subprogram
DIE has a name before creating the associated partial symbol.
(read_func_scope): Emit a complaint if the subprogram does not
have a name or when we can't extract the subprogram PC bounds.
gdb/testsuite/ChangeLog:
* gdb.dwarf2/dw2-anonymous-func.S: New file.
* gdb.dwarf2/dw2-anonymous-func.exp: New testcase.
Tested on x86_64-linux, no regression. Note that the testcase also
verifies that the psymtab->symtab conversion does not crash (this is
the purpose of the "list file1.txt:1" test.
