[LLVMdev] Emitting recursive types

[Renato Golin]

Hi James,

Last time I did this, there used to be PATypeHolder, which would take care
of incomplete types and replace all by complete when you finished, but more
than a year ago the StructType class was changed to accommodate that use
and the PATypeHolder was deprecated.

I believe you should use isOpaque and setBody functions from StructType.
Have a look at how Clang does it.

cheers,
--renato
