Functions change in CTFv4 by growing argument names as well as argument
types; the representation changes into a two-element array of (type, string
offset) rather than a simple array of arg types. Functions also gain an
explicit linkage in a different type kind (CTF_K_FUNC_LINKAGE, which
corresponds to BTF_KIND_FUNC).
New API:
typedef struct ctf_funcinfo {
/* ... */
- uint32_t ctc_argc; /* Number of typed arguments to function. */
+ size_t ctc_argc; /* Number of typed arguments to function. */
};
int ctf_func_arg_names (ctf_dict_t *, unsigned long, uint32_t, const char **);
int ctf_func_type_arg_names (ctf_dict_t *, ctf_id_t, uint32_t,
const char **names);
+extern int ctf_type_linkage (ctf_dict_t *, ctf_id_t);
-extern ctf_id_t ctf_add_function (ctf_dict_t *, uint32_t,
- const ctf_funcinfo_t *, const ctf_id_t *);
+extern ctf_id_t ctf_add_function (ctf_dict_t *, uint32_t,
+ const ctf_funcinfo_t *, const ctf_id_t *,
+ const char **arg_names);
+extern ctf_id_t ctf_add_function_linkage (ctf_dict_t *, uint32_t,
+ ctf_id_t, const char *, int linkage);
Adding this is fairly straightforward; the only annoying part is the way the
callers need to allocate space for the arg name and type arrays. Maybe we
should rethink these into something like ctf_type_aname(), allocating
space for the caller so the caller doesn't need to? It would certainly
make all the callers in libctf much less complex...
While we're at it, adjust ctf_type_reference, ctf_type_align, and
ctf_type_size for the new internal API changes (they also all have
special-case code for functions).
