Douglas Gregor f5974fa0d5 When we are instantiating a member function of a local class, be sure
to merge the local instantiation scope with the outer local
instantiation scope, so that we can instantiate declarations from the
function owning the local class. Fixes an assert while instantiating
Boost.MPL's BOOST_MPL_ASSERT_MSG.

Douglas Gregor 071676f422 Improve location information for Objective-C category declarations. We
previously only had a single location (the @ in @interface); now we
know where the @ is (for the start of the declaration), where the
class name is (that's the normal "location" now for diagnostics), and
where the category name is. Also, eliminated the redundant "end"
location, since ObjCContainerDecl already has better @end information.

The only XFAIL'd test is temporary; will un-XFAIL-it once I've taught
CIndex how to use the new locations.

Douglas Gregor 5fcb51c09c When determining whether a DeclRefExpr is value-dependent when it
references a const variable of integral type, the initializer may be
in a different declaration than the one that name-lookup saw. Find the
initializer anyway. Fixes PR6045.

Douglas Gregor d2e6a45722 When qualified lookup into the current instantiation fails (because it
finds nothing), and the current instantiation has dependent base
classes, treat the qualified lookup as if it referred to an unknown
specialization. Fixes PR6031.

Douglas Gregor ea0a0a9b3f Implement name lookup for conversion function template specializations
(C++ [temp.mem]p5-6), which involves template argument deduction based
on the type named, e.g., given

  struct X { template<typename T> operator T*(); } x;

when we call

  x.operator int*();

we perform template argument deduction to determine that T=int. This
template argument deduction is needed for template specialization and
explicit instantiation, e.g.,

  template<> X::operator float*() { /* ... */ }

and when calling or otherwise naming a conversion function (as in the
first example). 

This fixes PR5742 and PR5762, although there's some remaining ugliness
that's causing out-of-line definitions of conversion function
templates to fail. I'll look into that separately.

Ken Dyck 40775003e6 Roll out ASTContext::getTypeSizeInChars(), replacing instances of
"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits
ones as appropriate. 

Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType, 
fromQuantity(), and getQuantity() for clarity.

John McCall 1be1c63634 Add Expr::EvaluateAsBooleanCondition(), which does unprincipled folding to
try to evaluate an expression as a constant boolean condition.  This has
the same intended semantics as used in folding conditional operators.

Douglas Gregor a318efd1f2 Improve key-function computation for templates. In particular:
- All classes can have a key function; templates don't change that.
  non-template classes when computing the key function.
  - We always mark all of the virtual member functions of class
  template instantiations. 
  - The vtable for an instantiation of a class template has weak
  linkage. 

We could probably use available_externally linkage for vtables of
classes instantiated by explicit instantiation declarations (extern
templates), but GCC doesn't do this and I'm not 100% that the ABI
permits it.

John McCall 91f1a02648 Typedefs can be redeclared. That seems like something we should record in

Eli Friedman 84341cd668 Make sure to explicitly pass type/value dependence to Expr constructor. This
caught several cases where we were not doing the right thing. I'm
not completely sure all cases are being handled correctly, but this should
be an improvement.

Chandler Carruth 607f38e05f Correctly refer to element CVR qualifications when determining if a type is
more or less cv-qualified than another during implicit conversion and overload
resolution ([basic.type.qualifier] p5). Factors the logic out of template
deduction and into the ASTContext so it can be shared.

This fixes several aspects of PR5542, but not all of them.

Ted Kremenek b27a6d24a6 Add StmtIterator support for iterating over both the condition
variable initializer and the other expressions in an IfStmt.

This change required adding a 'DoDestroy()' method for IfStmt that did
not include destroying the initializer (since that is owned by the
VarDecl).

Douglas Gregor 033f675f61 When we see a CXXDefaultArgExpr during template instantiation, rebuild

Ted Kremenek 40ee0cc813 Tidy up ~ASTContext a bit by turning orphan compound statements into
for loops.  Also do not manually free the Type objects when the
'FreeMemory' flag is set, as they will be deallocated when the
BumpPtrAllocator is destroyed.

2009-12-23 21:13:52 +00:00
Douglas Gregor 25ab25f39d When using a default function argument for a function template (or
member function thereof), perform the template instantiation each time
the default argument is needed. This ensures that
  (1) We get different CXXTemporary objects for each instantiation, and
  (2) Any other instantiations or definitions triggered by the
  instantiation of the default argument expression are guaranteed to
  happen; previously, they might have been suppressed, e.g., because
  they happened in an unevaluated context.

This fixes the majority of PR5810. However, it does not address the
problem where we may have multiple uses of the same CXXTemporary
within an expression when the temporary came from a non-instantiated
default argument expression.
