Douglas Gregor d94105a1c2 Don't generate any code for an explicit call to a trivial destructor. 
Now that parsing, semantic analysis, and (I think) code generation of
pseudo-destructor expressions and explicit destructor calls works,
update the example-dynarray.cpp test to destroy the objects it
allocates and update the test to actually compile + link.
The code seems correct, but the Clang-compiled version dies with a
malloc error. Time to debug!

llvm-svn: 80722
 2009-09-01 21:12:16 +00:00
Anders Carlsson 6b8b4b459d We can generate constructors/destructors with base classes and non-trivial fields just fine now.

 2009-09-01 18:33:46 +00:00
Douglas Gregor 96ee789d33 Rename CXXQualifiedMemberExpr -> CXXAdornedMemberExpr, since we will 
also be adding explicit template arguments as an additional
"adornment". No functionality change.

Douglas Gregor c190523d7a When a member reference expression includes a qualifier on the member 
name, e.g.,
  
  x->Base::f()

retain the qualifier (and its source range information) in a new
subclass of MemberExpr called CXXQualifiedMemberExpr. Provide
construction, transformation, profiling, printing, etc., for this new
expression type.

When a virtual function is called via a qualified name, don't emit a
virtual call. Instead, call that function directly. Mike, could you
add a CodeGen test for this, too?

Mike Stump a5588bf3ac Implement virtual dispatch. :-) This is self-consistent with clang, 
but not yet necessarily perfectly consistent with gcc.  Also addressed
Doug and John's comments.

Mike Stump 2220447adc Ensure we don't output repeated vbase offsets. I have a testcase for 
this, but need to fixup the actual offset value before I can check it
in.  WIP.
