David Majnemer [Thu, 16 Jan 2014 20:05:57 +0000 (20:05 +0000)]
MS ABI: Improve selection of an inheritance model

The MSVC ABI is rather finicky about the exact representation of it's
pointer-to-member representation.  The exact position of when and where
it will go with one representation versus another appears to be when it
desires the pointer-to-member to be complete.

To properly implement this in clang, do several things:
- Give up on tracking the polymorphic nature of the class.  It isn't
  useful to Sema and is only pertinent when choosing CodeGen-time
  details like whether the field-offset can be 0 instead of -1.
- Insist on locking-in the inheritance model when we ask our
  pointer-to-member type to be complete.  From there, grab the
  underlying CXXRecordDecl and try to make *that* complete.  Once we've
  done this, we can calculate it's inheritance model and apply it using
  an attribute.

N.B. My first bullet point is a lie.  We will eventually care about the
specifics of whether or not a CXXRecordDecl is or is not polymorphic
because MSVC compatible mangling of such things depends on it.  However,
I believe we will handle this in a rather different way.

Switch this test from needlessly running the clang driver to directly
test the CC1 layer.

This actually uncovered that the test semes to no longer be passing for
the reasons intended. =[ The name of the test would lead me to believe
that it should be testing the semantics of noreturn in the static
analyzer.... but there are in fact no -verify assertions about noreturn
that i can find. And the noreturn checker is no longer in 'alpha.core'.
It is in 'core.builtins'. The test *does* have one assertion for a null
dereference warning. This *also* isn't in 'alpha.core', but the driver
inserts a pile of other checker packages, including 'core' which has
this warning.

So I have switch the RUN line to actually do the minimal thing that this
test currently exercises, but someone who works on the static analyzer
should probably look at this and either nuke it or move it to actually
check the noreturn behavior.
