In D, all named enums are explicitly scoped (the C++ equivalent of enum class)
so they should be handled as such in the language-specific symbol lookup
routines. However so as to support D compilers that don't emit enums as
DW_AT_enum_class, need to make sure that appropriate checks for
TYPE_DECLARED_CLASS are done.
gdb/ChangeLog
* d-exp.y (type_aggregate_p): New function.
(PrimaryExpression : TypeExp '.' IdentifierExp): Use it.
(classify_inner_name): Likewise.
* d-namespace.c (d_lookup_nested_symbol): Handle TYPE_CODE_ENUM.
In D, there is the notion of modules, and importing from one to the other,
whether it is a basic, selective or renamed import declaration.
module A;
import X;
void foo() {
import Y : bar;
}
If the compiler emits DW_TAG_imported_declaration at the appropriate locations,
then we can make use of what gdb stores in using_direct when performing
nonlocal symbol lookups.
gdb/ChangeLog
* Makefile.in (SFILES): Add d-namespace.c.
(COMMON_OBS): Add d-namespace.o.
* d-lang.c (d_language_defn): Use d_lookup_symbol_nonlocal as the
la_lookup_symbol_nonlocal callback function pointer.
* d-lang.h (d_lookup_symbol_nonlocal): New declaration.
(d_lookup_nested_symbol): New declaration.
* d-namespace.c: New file.
