Douglas Gregor 38fee967ae Instantiation of template template parameters for nested templates, e.g.,
template<typename T>
  struct X {
    template<template<T Value> class Y> struct Inner;

Douglas Gregor 36d7c5f29b Improve instantiation of default template arguments for nested
templates. The instantiation of these default arguments must be (and
now, is) delayed until the template argument is actually used, at
which point we substitute all levels of template arguments
concurrently.

Douglas Gregor 0840cc02ce When determining whether a reference to a static data member is an
integral constant expression, make sure to find where the initializer
was provided---inside or outside the class definition---since that can
affect whether we have an integral constant expression (and, we need
to see the initializer itself).

Douglas Gregor 954de17977 Implement "incremental" template instantiation for non-type template
parameters and template type parameters, which occurs when
substituting into the declarations of member templates inside class
templates. This eliminates errors about our inability to "reduce
non-type template parameter depth", fixing PR5311.

Also fixes a bug when instantiating a template type parameter
declaration in a member template, where we weren't properly reducing
the template parameter's depth.

LLVM's StringSwitch header now parses.

Preserve source information through template instantiation.  This is made

is possibly worth fixing in the future.

2009-10-14 20:14:33 +00:00
Douglas Gregor cf91555cb8 When explicitly specializing a member that is a template, mark the
template as a specialization. For example, this occurs with:

  template<typename T>
  struct X {
    template<typename U> struct Inner { /* ... */ };
  };

  template<> template<typename T>
  struct X<int>::Inner {
    T member;
  };

We need to treat templates that are member specializations as special
in two contexts:

  - When looking for a definition of a member template, we look
    through the instantiation chain until we hit the primary template
    *or a member specialization*. This allows us to distinguish
    between the primary "Inner" definition and the X<int>::Inner
    definition, above.
  - When computing all of the levels of template arguments needed to
    instantiate a member template, don't add template arguments
    from contexts outside of the instantiation of a member
    specialization, since the user has already manually substituted
    those arguments.

Fix up the existing test for p18, which was actually wrong (but we
didn't diagnose it because of our poor handling of member
specializations of templates), and add a new test for member
specializations of templates.

Douglas Gregor 3a88c1d784 Improve the internal representation and semantic analysis of friend
function templates.

This commit ensures that friend function templates are constructed as
FunctionTemplateDecls rather than partial FunctionDecls (as they
previously were). It then implements template instantiation for friend
function templates, injecting the friend function template only when
no previous declaration exists at the time of instantiation. 

Oh, and make sure that explicit specialization declarations are not
friends.

Douglas Gregor ef06ccf8d0 When declaring a class template whose name is qualified, make sure
that the scope in which it is being declared is complete. Also, when
instantiating a member class template's ClassTemplateDecl, be sure to
delay type creation so that the resulting type is dependent. Ick.

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.

when we are not instantiating the corresponding "current

occurs in a default function argument. The libstdc++ vector default
constructor now instantiates properly.
