of that parameter, reduce the level by the number of active template
argument lists rather than by 1. The number of active template
argument lists is only > 1 when we have a class template partial
specialization of a member template of a class template that itself is
a member template of another class template.
... and Boost.MSM does this. Fixes PR7669.

namely when the friend function prototype is already used
at the point of the template definition that is supposed
to inject the friend function. Testcase verifies four
scenarios.
I would like receive some code review for this.

a template-argument-list. When template template parameters are
involved, we won't already have checked the template-argument-list (it
may not be known yet!). Fixes PR7807.

dependent bases, construct a dependent nested-name-specifier rather
than complaining that the name could not be found within the current
instantiation itself. Fixes PR7725.

expression such as the "foo" in "this->blah.foo<1, 2>", and we can't
look into the type of "this->blah" (e.g., because it is dependent),
look into the local scope of a template of the same name. Fixes
<rdar://problem/8198511>.

definition, we're likely going to end up breaking the invariants of
the template system, e.g., that the depths of template parameter lists
match up with the nesting template of the template. So, make sure we
mark such ill-formed declarations as invalid or don't even build them
at all.

This flag and warning match GCC semantics. Also, move it to -Wextra as this is
a largely cosmetic issue and doesn't seem to mask problems. Subsequent fixes to
the tests which no longer by default emit the warning. Added explicit test
cases for both C and C++ behavior with the warning turned on.
llvm-svn: 108325
strip cv-qualifiers from the expression's type when the language calls
for it: in C, that's all the time, while C++ only does it for
non-class types.
Centralized the computation of the call expression type in
QualType::getCallResultType() and some helper functions in other nodes
(FunctionDecl, ObjCMethodDecl, FunctionType), and updated all relevant
callers of getResultType() to getCallResultType().
Fixes PR7598 and PR7463, along with a bunch of getResultType() call
sites that weren't stripping references off the result type (nothing
stripped cv-qualifiers properly before this change).
llvm-svn: 108234
class templates within class scope (which is ill-formed), and recover
by dropping the explicit specialization entirely. Fixes the infinite
loop in PR7622.
llvm-svn: 108217
default arguments to template parameters don't have a DeclContext when
instantiated, and so we can't detect that we're in an instantiation context as
opposed to the definition context. However, it fixes the more commonly-occuring
cases in TMP code that use devolve to this type of tautology after
substitution.

current attribute system, but it is enough to handle class templates which
specify parts of their alignment in terms of their template parameters.
This also replaces the attributes test in SemaTemplate with one that actually
tests working attributes instead of broken ones. I plan to add more tests here
for non-dependent attributes in a subsequent patch.
Thanks to John for walking me through some of this. =D

attribute as part of the calculation. Sema::MarkDeclReferenced(), and
a few other places, want only to consider the "used" bit to determine,
e.g, whether to perform template instantiation. Fixes a linkage issue
with Boost.Serialization.

(or operator-function-id) as a template, but the context is actually
non-dependent or the current instantiation, allow us to use knowledge
of what kind of template it is, e.g., type template vs. function
template, for further syntactic disambiguation. This allows us to
parse properly in the presence of stray "template" keywords, which is
necessary in C++0x and it's good recovery in C++98/03.
llvm-svn: 106167
disambiguation keywords outside of templates in C++98/03. Previously,
the warning would fire when the associated nested-name-specifier was
not dependent, but that was a misreading of the C++98/03 standard:
now, we complain only when we're outside of any template.
