Add an opque payload field to lldb::Type (NFC).

Authored by aprantl on Mar 3 2020, 1:16 PM.



This hides the language-specific flags and lets each language define its own fields in the opaquer storage.

Thanks for working to make LLDB more language-agnostic!

Document layout.

I want to see how you end up resolving the comments on payload being a plain integer type in D75626 before looking at this again. Maybe it makes more sense to use a type, the use is pretty clever but perhaps makes for opaque code in some places.

Address feedback from Pavel and add the payload to the constructor.

It doesn't look like this setter is needed, as the single usage has now been changed to a constructor argument. And if this is immutable, then in turn some methods of TypePayloadClang become unneeded (SetIsCompleteObjCClass)


maybe make this explicit too (and augment it with a encode method to make the usage less weird)?

Rebase and update based on It no longer takes a reference, but is a value type instead.

Remove the obsolete setter in lldb::Type.

Could you make the uint32_t a typedef? I'm fine with this not being type-safe, but a typedef would at least allow me to search for where this information is used. Grepping/searching for uint32_t isn't a great experience. It would also make this interface more self-documenting.

Beside that LGTM.
