2019-05-28libctf: core type lookupNick Alcock1-0/+195
Finally we get to the functions used to actually look up and enumerate properties of types in a container (names, sizes, members, what type a pointer or cv-qual references, determination of whether two types are assignment-compatible, etc). With a very few exceptions these do not work for types newly added via ctf_add_*(): they only work on types in read-only containers, or types added before the most recent call to ctf_update(). This also adds support for lookup of "variables" (string -> type ID mappings) and for generation of C type names corresponding to a type ID. libctf/ * ctf-decl.c: New file. * ctf-types.c: Likewise. * ctf-impl.h: New declarations. include/ * ctf-api.h (ctf_visit_f): New definition.
