A previous change enabled running OIL tests with specific features enabled.
This highlighted that pointer code generation under TreeBuilder-v2 was very
broken. This change updates pointer code generation to work and enables the
skipped tests. All enabled tests need `expected_json_v2` added to them due to
formatting differences.
Reformatted and rewrote the basic type handler that handles primitives and
pointers. Removed the reliance on `features` to decide whether to generate for
TreeBuilder-v2 as the intermediate features have been removed. Pointers are
treated as containers with a capacity of 1 and a length of 0 if null/a cycle
and 1 if followed. This holds for void pointers where, although they aren't
followed, the length is still set.
There were a couple of other changes needed to enable these tests on TBv2 that
aren't worth their own issues and PRs, I sneaked them in here.
Extra changes:
- Added `Pointer` and `Reference` to TopoSorter so they generate
`NameProvider` instances. It might be worth visiting the graph differently
for `NameProvider` as it requires so many instances that others generators do
not. Will consider that in the future.
- Follow typedefs when calculating exclusive size for a type.
Closes#458.
Test plan:
- CI
- Enabled previously disabled tests.
Array members are currently being named "TODO" (whoops). Include arrays in
TopoSorter so each one can have a `NameProvider` generated in CodeGen. Then
pass array elements through `make_field`.
Test plan:
- CI
- Add array member names to an array test.
For the containers which are allowed to be declared with incomplete
types, it is only the contained types which are allowed to be
incomplete. Other template parameters (e.g. allocators) must always be
defined before use.
Types within containers were previously named TODO. This sorts it out so
they're named as their most resolved type. The current implementation
skips Typedef names.
These aren't used for anything yet, but should be useful for stable IDs
when printing nodes before and after passes and for faster cycle
detection than the current map of pointers.
For std::vector and std::list, template parameters are not required to
be defined before they can be used. Delay sorting them until the end.
Also fix a CodeGen bug where we were defining typedefs in the middle of
the forward declarations. They only need to be defined when other types
are defined.
