33cdd81064
Rework how CIndex handles diagnostics. Rather than using a callback,
...
we attach diagnostics to translation units and code-completion
results, so they can be queried at any time.
To facilitate this, the new StoredDiagnostic class stores a diagnostic
in a serializable/deserializable form, and ASTUnit knows how to
capture diagnostics in this stored form. CIndex's CXDiagnostic is a
thin wrapper around StoredDiagnostic, providing a C interface to
stored or de-serialized diagnostics.
I've XFAIL'd one test case temporarily, because currently we end up
storing diagnostics in an ASTUnit that's never returned to the user
(because it contains errors). I'll introduce a temporary fix for this
soon; the real fix will be to allow us to return and query invalid ASTs.

Cope with anonymous tags defined within declarators by structurally
...
comparing their types under the assumption that they are equivalent,
rather than importing the types and then checking for compatibility. A
few minor tweaks here:
- Teach structural matching to handle compatibility between
function types with prototypes and those without prototypes.
- Teach structural matching that an incomplete record decl is the
same as any other record decl with the same name.
- Keep track of pairs of declarations that we have already checked
(but failed to find as structurally matching), so we don't emit
diagnostics repeatedly.
- When importing a typedef of an anonymous tag, be sure to link the
imported tag type to its typedef.
With these changes, we survive a repeated import of <stdlib.h> and
<stdio.h>. Alas, the ASTNodeImporter is getting a little grotty.
