add them to a fast lookup map. lldb_private::Symtab now export the following
public typedefs:
namespace lldb_private {
class Symtab {
typedef std::vector<uint32_t> IndexCollection;
typedef UniqueCStringMap<uint32_t> NameToIndexMap;
};
}
Clients can then find symbols by name and or type and end up with a
Symtab::IndexCollection that is filled with indexes. These indexes can then
be put into a name to index lookup map and control if the mangled and
demangled names get added to the map:
bool add_demangled = true;
bool add_mangled = true;
Symtab::NameToIndexMap name_to_index;
symtab->AppendSymbolNamesToMap (indexes, add_demangled, add_mangled, name_to_index).
This can be repeated as many times as needed to get a lookup table that
you are happy with, and then this can be sorted:
name_to_index.Sort();
Now name lookups can be done using a subset of the symbols you extracted from
the symbol table. This is currently being used to extract objective C types
from object files when there is no debug info in SymbolFileSymtab.
Cleaned up how the objective C types were being vended to be more efficient
and fixed some errors in the regular expression that was being used.
