We are creating the typedef DIE as limbo as we create it from here:
/* If TYPE is a typedef type variant, let's generate debug info
for the parent typedef which TYPE is a type of. */
if (typedef_variant_p (type))
{
if (TREE_ASM_WRITTEN (type))
return;
/* Prevent broken recursion; we can't hand off to the same type. */
gcc_assert (DECL_ORIGINAL_TYPE (TYPE_NAME (type)) != type);
/* Use the DIE of the containing namespace as the parent DIE of
the type description DIE we want to generate. */
if (DECL_CONTEXT (TYPE_NAME (type))
&& TREE_CODE (DECL_CONTEXT (TYPE_NAME (type))) == NAMESPACE_DECL)
context_die = get_context_die (DECL_CONTEXT (TYPE_NAME (type)));
TREE_ASM_WRITTEN (type) = 1;
gen_decl_die (TYPE_NAME (type), NULL, context_die);
and the DECL_CONTEXT of the TYPE_DECL is the translation unit. Not sure
why we do not immediately using such kind of context here, similar
in the case of is_naming_typedef_decl () below.
Thus, the following fixes it:
