John McCall 7decc9e4ea Calculate the value kind of an expression when it's created and
store it on the expression node.  Also store an "object kind",
which distinguishes ordinary "addressed" l-values (like
variable references and pointer dereferences) and bitfield,
@property, and vector-component l-values.

Currently we're not using these for much, but I aim to switch
pretty much everything calculating l-valueness over to them.
For now they shouldn't necessarily be trusted.

Douglas Gregor ee430a39c3 Implement C++0x [temp.func.order]p3 (aka DR532) properly. In
particular, we only add the implement object parameter type if only
one of the function templates is a non-static member function
template.

Moreover, since this DR differs from existing practice in C++98/03,
this commit implements the existing practice (which ignores the
first parameter of the function template that is not the non-static
member function template) in C++98/03 mode.

Douglas Gregor 869853eea1 Instantiate class member template partial specialization declarations
in the order they occur within the class template, delaying
out-of-line member template partial specializations until after the
class has been fully instantiated. This fixes a regression introduced
by r118454 (itself a fix for PR8001).

Douglas Gregor c0d2490ac4 In the presence of using declarations, we can find the same class
members in class subobjects of different types. So long as the
underlying declaration sets are the same, and the declaration sets
involve non-instance members, this is not an ambiguity.

Douglas Gregor 7731d3fafc Teach the warning about unnamed/local types in template arguments to
actually walk the template argument type to find any unnamed/local
types within it. Fixes PR6784.

2010-10-13 00:27:52 +00:00
Douglas Gregor 5bb5e4ad9d Introduce support for emitting diagnostics (warnings + their notes)
that are suppressed during template argument deduction. This change
queues diagnostics computed during template argument deduction. Then,
if the resulting function template specialization or partial
specialization is chosen by overload resolution or partial ordering
(respectively), we will emit the queued diagnostics at that point. 

This addresses most of PR6784. However, the check for unnamed/local
template arguments (which existed before this change) is still only
skin-deep, and needs to be extended to look deeper into types. It must
be improved to finish PR6784.

Douglas Gregor 6e9cf630f8 When finalizing a function template specialization following template
argument deduction, make sure to check the correctness of deduced template
type arguments (which we had previously skipped) along with other
kinds of template arguments. This fixes part of PR6784, but we're
still swallowing the extension warning about unnamed/local template
arguments.

Douglas Gregor 758cb67fcf If we end up instantiating a function parameter whose default argument
has not yet been parsed, note that the default argument hasn't been
parsed and keep track of all of the instantiations of that function
parameter. When its default argument does get parsed, imbue the
instantiations with that default argument. Fixes PR8245.

Douglas Gregor 009f69979a When dealing with an anonymous enumeration declared in function
prototype scope, temporarily set the context of the enumeration
declaration to the translation unit. We do the same thing for
parameters, until we have an actual function declaration on which to
hang them. Fixes <rdar://problem/8435682>.

There is more work to do in this area, since we have existing bugs
with tags being declared/defined in function parameter lists. This fix
is correct, and we'll end up extending it when we deal with those
existing bugs.

Douglas Gregor 8ce63154d0 When diagnosing C++ [temp.expl.spec]p3 in C++98/03 mode, downgrade the
error to a warning if we're in a case that would be allowed in
C++0x. This "fixes" PR8084 by making Clang accept more code than GCC
and (non-strict) EDG do. 

Also, add the missing test case for the C++0x semantics, which should
have been in r113717.
