We used to support having a single `void` argument. It was for some
C-compatibility ambitions, but just omitting the argument is perfectly
fine.
Also, the DWARF importer has been fixed to handle typedef'd void as
arguments.
More in general, arguments are now required to always have a size.
Replace the stub implementation of invalidation with the proper
implementation. A ReadPathCache is added to each global so that it can
keep tracks of what target are associated to which read paths.
One of the two passes to purge unused types from the model had a
ill-defined semantics.
This commit simplifies them in two passes: one that purges all the types
unreachable from outside `Binary::Types` and one that does the same but
also preserves types with a `CustomName` or an `OriginalName`.
This commit improves the formalization of how we handle names.
The main changes are:
* Now `_` is a reserved prefix and all the generated names start with
`_`.
* The model verification routine now checks that `CustomName`s in the
global scope do not collide with any local namespace (e.g., fields of
a `StructType`).
* We changed the prefix `prefix_` to `unreserved_` to better convey the
fact that the prefix has been introduce to use an non-reserved name.
This commit completes the support of various rare PrimitiveTypes, that
has been added opportunistically over time and has remained inconsistent
across the codebase:
- float80_t
- float96_t
- generic80_t
- generic96_t
The first two are necessary because on some platforms long double is
either 10 or 12 bytes wide.
The second two are necessary because the Generic PrimitiveType should
allow all non-zero byte sizes allowed by any other PrimitiveType.
`Segment` now includes a `Type` of struct kind. This is intended to
emit the segment as a struct later in decompilation. The implementation
of name has also been added.
