Based on work from Daniel Jacobowitz <dan@codesourcery.com>
* c-typeprint.c (cp_type_print_method_args): For non-static methods,
print out const or volatile qualifiers, too.
(c_type_print_args): Add parameters show_artificial and language.
Skip artificial parameters when requested.
Use the appropriate language printer.
(c_type_print_varspec): Tell c_type_print_args to skip artificial
parameters and pass language_c.
* dwarf2read.c (die_list): New file global.
(struct partial_die_info): Update comments for name field.
(pdi_needs_namespace): Renamed to ...
(die_needs_namespace): ... this. Rewrite.
(dwarf2_linkage_name): Remove.
(add_partial_symbol): Do not predicate the call to
partial_die_full_name based on pdi_needs_namespace.
Remove call to cp_check_possible_namespace_symbols and associated
outdated comments.
(guess_structure_name): Do not inspect child subprogram DIEs.
(dwarf2_fullname): Update comments.
Use die_needs_namespace to assist in computing the name.
(read_func_scope): Use dwarf2_name to get the DIE's name.
Use dwarf2_physname to get the "linkage name" of the DIE.
(dwarf2_add_member_field): Use dwarf2_physname instead of
dwarf2_linkage_name.
(read_structure_type): For structs and classes, set TYPE_NAME, too.
(determine_class): Remove.
(read_partial_die): Ignore DW_AT_MIPS_linkage_name for all languages
except Ada.
(new_symbol): Unconditionally call dwarf2_name.
Compute the "linkage name" using dwarf2_physname.
Use dwarf2_name instead of dwarf2_full_name for enumerator DIEs.
When determining to scan for anonymous C++ namespaces, ignore
the linkage name.
(dwarf2_physname): New function.
(dwarf2_full_name): Move content to new function and call
that.
(dwarf2_compute_name): "New" function.
(_initialize_dwarf2_read): Initialize die_list.
* gnu-v3-eabi.c (gnu_v3_find_method_in): Remove unused variable
physname.
(gnu_v3_print_method_ptr): Use the physname for virtual methods
without a demangled name.
Print out type information for non-virtual methods.
* linespec.c (decode_line_1): Force ANY string using "::" (or
"." for java) to use decode_compound, and clean up any stray quoting.
If we found a file symtab, re-evaluate whether the remainder is_quoted.
(decode_compound): Stop consuming at an open parenthesis.
Keep template parameters.
Keep any overload information.
Keep keywords like "const".
Remove paren_pointer.
Move is_quoted check from set_flags to here.
Remove #if 0 code from 2000. Ten years is long enough.
(find_method): Before comparing symbol names, canonicalize the string
from the user.
If a specific overload is requested, find it. Otherwise throw an error.
(find_method_overload_end): New function.
(set_flags): Remove.
(decode_compound): Assume that parentheses are matched.
It's a lot easier.
* symtab.c (symbol_find_demangled_name): Add DMGL_VERBOSE flag
to cplus_demangle.
* linespec.c (decode_line_1): Keep important keywords like
"const" and "volatile".
* symtab.h (SYMBOL_CPLUS_DEMANGLED_NAME): Remove.
* typeprint.h (c_type_print_args): Add declaration.
* ui-file.c (do_ui_file_obsavestring): New function.
(ui_file_obsavestring): New function.
* ui-file.h (ui_file_obsavestring): Add declaration.
* valops.c (find_overload_match): Resolve the object to
a non-pointer type.
If the object is a data member, search the object for the member
and return with staticp set.
Use SYMBOL_NATURAL_NAME instead of SYMBOL_CPLUS_DEMANGLED_NAME.
Do not attempt to extract a function name from non-function types.
If the extracted function name and the original name are the same,
we don't have a C++ method.
From Jan Kratochvil <jan.kratochvil@redhat.com>:
* dwarf2read.c (new_symbol <DW_TAG_enumerator>): Call dwarf2_full_name.
* ada-lang.c (ada_lookup_symbol): Remove linkage_name parameters
and arguments from symbol lookups.
* ax-gdb.c (gen_expr): Likewise.
* cp-namespace.c (cp_lookup_symbol_nonlocal, lookup_namespace_scope,
cp_lookup_symbol_namespace, lookup_symbol_file, lookup_nested_type,
lookup_possible_namespace_symbol): Likewise.
* cp-support.c (read_in_psymtabs): Likewise.
* cp-support.h (cp_lookup_symbol_nonlocal): Likewise.
* language.h (la_lookup_symbol_nonlocal): Likewise.
* scm-valprint.c (scm_inferior_print): Likewise.
* solib-darwin.c (darwin_relocate_section_addresses): Likewise.
* solib-svr.c (elf_lookup_lib): Likewise.
* solib.c (show_auto_solib_add): Likewise.
* solist.h (lookup_lib_global, solib_global_lookup): Likewise.
* symmisc.c (maintenance_check_symtabs): Likewise.
* symtab.c (lookup_symbol_in_language, lookup_symbol_aux,
lookup_symbol_aux_local, lookup_symbol_aux_block,
lookup_symbol_from_objfile, lookup_symbol_aux_symtabs,
lookup_symbol_aux_psymtabs,basic_lookup_symbol_nonlocal,
lookup_symbol_static, lookup_symbol_global, symbol_matches_domain,
basic_lookup_transparent_type, find_main_psymtab,
lookup_block_symbol): Likewise.
* symtab.h (basic_lookp_symbol_nonlocal, lookup_symbol_static,
lookup_symbol_global, lookup_symbol_aux_block,
lookup_symbol_partial_symbol, lookup_block_symbol,
lookup_global_symbol, value_maybe_namespace_elt): Likewise.
