Douglas Gregor d90fd526d3 Declarators can now properly represent template-ids, e.g., for
template void f<int>(int);
                ~~~~~~
Previously, we silently dropped the template arguments. With this
change, we now use the template arguments (when available) as the
explicitly-specified template arguments used to aid template argument
deduction for explicit template instantiations.

Douglas Gregor 450f0084a2 WIP implementation of explicit instantiation of function templates,
member functions of class template specializations, and static data
members. The mechanics are (mostly) present, but the semantic analysis
is very weak.

Douglas Gregor 56751b5981 Fix checking for a null pointer constant when the expression itself is
value-dependent. Audit (and fixed) all calls to
Expr::isNullPointerConstant() to provide the correct behavior with
value-dependent expressions. Fixes PR5041 and a crash in libstdc++
<locale>.

In the same vein, properly compute value- and type-dependence for
ChooseExpr. Fixes PR4996.

Douglas Gregor 5013a7e42d When entering the scope of a declarator, make sure that the scope is
complete (or, possibly causing template instantiation).

Test this via some explicit specializations of member functions.

Douglas Gregor 3a923c2d37 WIP implementation of explicit function template specialization. This
first implementation recognizes when a function declaration is an
explicit function template specialization (based on the presence of a
template<> header), performs template argument deduction + ambiguity
resolution to determine which template is being specialized, and hooks

There are many caveats here:
  - We completely and totally drop any explicitly-specified template
  arguments on the floor
  - We don't diagnose any of the extra semantic things that we should
  diagnose. 
  - I haven't looked to see that we're getting the right linkage for
  explicit specializations

On a happy note, this silences a bunch of errors that show up in
libstdc++'s <iostream>, although Clang still can't get through the
entire header.

Fariborz Jahanian af0262dccf This patch addresses a few issues related to 8.5.3 [dcl.init.ref]
It uses a recent API to find inherited conversion functions to do
the initializer to reference lvalue conversion (and removes a FIXME).
It issues the ambiguity diagnostics when multiple conversions are found.

Douglas Gregor 5bf52697b0 Tweak the code-completion results ranking and formation, so that
members found in base classes have the same ranking as members found
in derived classes. However, we will introduce an informative note for
members found in base classes, showing (as a nested-name-specifier)
the qualification to name the base class, to make it clear which
members are from bases.

Douglas Gregor cabea40ea3 Implement code completion within a function call, triggered after the
opening parentheses and after each comma. We gather the set of visible
overloaded functions, perform "partial" overloading based on the set
of arguments that we have thus far, and return the still-viable
results sorted by the likelihood that they will be the best candidate.

Most of the changes in this patch are a refactoring of the overloading
routines for a function call, since we needed to separate out the
notion of building an overload set (common to code-completion and
normal semantic analysis) and then what to do with that overload
set. As part of this change, I've pushed explicit template arguments
into a few more subroutines.

There is still much more work to do in this area. Function templates
won't be handled well (unless we happen to deduce all of the template
arguments before we hit the completion point), nor will overloaded
function-call operators or calls to member functions.

John McCall 9dd450bb78 Change all the Type::getAsFoo() methods to specializations of Type::getAs().
Several of the existing methods were identical to their respective
specializations, and so have been removed entirely.  Several more 'leaf'
optimizations were introduced.

The getAsFoo() methods which imposed extra conditions, like
getAsObjCInterfacePointerType(), have been left in place.

Douglas Gregor 2af2f670d1 When providing a code-completion suggestion for a hidden name, include
a nested-name-specifier that describes how to refer to that name. For
example, given:

  struct Base { int member; };
  struct Derived : Base { int member; };

the code-completion result for a member access into "Derived" will
provide both "member" to refer to Derived::member (no qualification needed) and
"Base::member" to refer to Base::member (qualification included).

Douglas Gregor f251067530 Enhance "case" code completion in C++ to suggest qualified names for
enumerators when either the user intentionally wrote a qualified name
(in which case we just use that nested-name-specifier to match
the user's code) or when this is the first "case" statement and we
need a qualified name to refer to an enumerator in a different scope.

Douglas Gregor b5c738b434 In C++ code completion, only suggest the "template" keyword after ".",

2009-09-18 23:55:56 +00:00
Douglas Gregor ce23bae4f8 Make the construction of the code-completion string for a function
template smarter, by taking into account which function template
parameters are deducible from the call arguments. For example,

  template<typename RandomAccessIterator>
  void sort(RandomAccessIterator first, RandomAccessIterator last);

will have a code-completion string like

  sort({RandomAccessIterator first}, {RandomAccessIterator last})

since the template argument for its template parameter is
deducible. On the other hand,

  template<class X, class Y>
  X* dyn_cast(Y *Val);

will have a code-completion string like

  dyn_cast<{class X}>({Y *Val})

since the template type parameter X is not deducible from the function
call.
