HAS_DECL_ASSEMBLER_NAME_P is:
#define HAS_DECL_ASSEMBLER_NAME_P(NODE) \
(CODE_CONTAINS_STRUCT (TREE_CODE (NODE), TS_DECL_WITH_VIS))
FUNCTION_DECL is defined as:
DEFTREECODE (FUNCTION_DECL, "function_decl", tcc_declaration, 0)
#define MARK_TS_DECL_WITH_VIS(C) \
(MARK_TS_DECL_WRTL (C), \
tree_contains_struct[C][TS_DECL_WITH_VIS] = true)
#define MARK_TS_DECL_NON_COMMON(C) \
(MARK_TS_DECL_WITH_VIS (C), \
tree_contains_struct[C][TS_DECL_NON_COMMON] = true)
initialize_tree_contains_struct does:
code = (enum tree_code) i;
ts_code = tree_node_structure_for_code (code);
/* Mark the TS structure itself. */
tree_contains_struct[code][ts_code] = 1;
/* Mark all the structures that TS is derived from. */
switch (ts_code)
...
case TS_TYPE_DECL:
case TS_FUNCTION_DECL:
MARK_TS_DECL_NON_COMMON (code);
break;
tree_node_structure_for_code is defined by:
static inline enum tree_node_structure_enum
tree_node_structure_for_code (enum tree_code code)
{
switch (TREE_CODE_CLASS (code))
{
case tcc_declaration:
switch (code)
{
case CONST_DECL: return TS_CONST_DECL;
case DEBUG_EXPR_DECL: return TS_DECL_WRTL;
case FIELD_DECL: return TS_FIELD_DECL;
case FUNCTION_DECL: return TS_FUNCTION_DECL;
So the answer to `HAS_DECL_ASSEMBLER_NAME_P return false` is no it does not.
Are you sure looking at the correct `__ct` function_decl? There are a couple of
clones of the constructor decl due to in-charge ABI reasons.
