Douglas Gregor ee9067c51f When we have a non-dependent expression such as
A::f

that occurs within a non-static member function with a type-dependent
"this", don't consider this to be a case for introduction of an
implicit "(*this)." to refer to a specific member function unless we
know (at template definition time) that A is a base class of *this.

There is some disagreement here between GCC, EDG, and Clang about the
handling of this case. I believe that Clang now has the correct,
literal interpretation of the standard, but have asked for
clarification (c++std-core-15483).

Douglas Gregor ad2956c25d Cope with an amusingly little anomaly with dependent types and
incomplete array initialization, where we have the following in a
template:

  int a[] = { 1, 2, something-value-dependent };
  // ...
  sizeof(a);

The type of "a" appears to be a non-dependent IncompleteArrayType, but
treating it as such makes the sizeof(a) fail at template definition
time. We now correctly handle this by morphing the IncompleteArrayType
into a DependentSizedArrayType with a NULL expression, indicating that
its size has no corresponding expression (and, therefore, the type is
distinct from others).

Sebastian Redl 7c353685bc - Have TryStaticImplicitCast set the cast kind to NoOp when binding a reference. CheckReferenceInit already inserts implicit casts to the necessary types. This fixes an assertion in CodeGen for some casts and brings a fix for PR5453 close, if I understand that bug correctly.
- Also, perform calculated implicit cast sequences if they're determined to work. This finally diagnoses static_cast to ambiguous or implicit bases and fixes two long-standing fixmes in the test case. For the C-style cast, this requires propagating the access check suppression pretty deep into other functions.
- Pass the expressions for TryStaticCast and TryStaticImplicitCast by reference. This should lead to a better AST being emitted for such casts, and also fixes a memory leak, because CheckReferenceInit and PerformImplicitConversion wrap the node passed to them. These wrappers were previously lost.

  - Comparing template parameter lists to determine if we have equivalent

  - Comparing template parameter lists to determine whether a template 
    template argument is valid for a given template template parameter.

Previously, we did not distinguish between the last two cases, which
got us into trouble when we were looking for exact type matches
between the types of non-type template parameters that were dependent
types. Now we do, so we properly delay checking of template template
arguments until instantiation time.

Also, fix an accidental fall-through in a case statement that was

Douglas Gregor 84d49a2085 Improve diagnostics when a default template argument does not match
with its corresponding template parameter. This can happen when we
performed some substitution into the default template argument and
what we had doesn't match any more, e.g.,

  template<int> struct A;
  template<typename T, template<T> class X = A> class B;

  B<long> b;

Previously, we'd emit a pretty but disembodied diagnostic showing how
the default argument didn't match the template parameter. The
diagnostic was good, but nothing tied it to the *use* of the default
argument in "B<long>". This commit fixes that.

Also, tweak the counting of active template instantiations to avoid
counting non-instantiation records, such as those we create for
(surprise!) checking default arguments, instantiating default
arguments, and performing substitutions as part of template argument
deduction.

llvm-svn: 86884
2009-11-11 21:54:23 +00:00
Douglas Gregor e62e6a0191 Before checking a template template argument against its corresponding
template template parameter, substitute any prior template arguments
into the template template parameter. This, for example, allows us to
properly check the template template argument for a class such as:

  template<typename T, template<T Value> class X> struct Foo;

The actual implementation of this feature was trivial; most of the
change is dedicated to giving decent diagnostics when this
substitution goes horribly wrong. We now get a note like:

  note: while substituting prior template arguments into template
      template parameter 'X' [with T = float]

As part of this change, enabled some very pedantic checking when
comparing template template parameter lists, which shook out a bug in
our overly-eager checking of default arguments of template template
parameters. We now perform only minimal checking of such default
arguments when they are initially parsed.

Douglas Gregor 120635bc9c Fix speculative parsing of dependent template names in
nested-name-specifiers so that they don't gobble the template name (or
operator-function-id) unless there is also a
template-argument-list. For example, given

  T::template apply

we would previously consume both "template" and "apply" as part of
parsing the nested-name-specifier, then error when we see that there
is no "<" starting a template argument list. Now, we parse such
constructs tentatively, and back off if the "<" is not present. This
allows us to parse dependent template names as one would use them for,
e.g., template template parameters:

  template<typename T, template<class> class X = T::template apply>
    struct MetaSomething;

Also, test default arguments for template template parameters.

Douglas Gregor 9167f8bbd5 Introduce a new representation for template template
parameters. Rather than storing them as either declarations (for the
non-dependent case) or expressions (for the dependent case), we now
(always) store them as TemplateNames. 

The primary change here is to add a new kind of TemplateArgument,
which stores a TemplateName. However, making that change ripples to
every switch on a TemplateArgument's kind, also affecting
TemplateArgumentLocInfo/TemplateArgumentLoc, default template
arguments for template template parameters, type-checking of template
template arguments, etc.

This change is light on testing. It should fix several pre-existing
problems with template template parameters, such as:
  - the inability to use dependent template names as template template
  arguments
  - template template parameter default arguments cannot be
  instantiation

However, there are enough pieces missing that more implementation is
required before we can adequately test template template parameters.

2. Explicit and implicit constructors get the same diagnostics.

3. The AST explicitly contains constructor calls from implicit default
constructors.  This allows handing some cases that previously weren't handled
correctly in IRGen without any additional code. Specifically, implicit default
constructors containing calls to constructors with default arguments are now
handled correctly.

John McCall 99ce6bfe28 Improve the -Wsign-compare heuristics:
* If the unsigned type is smaller than the signed type, never warn, because
    its value will not change when zero-extended to the larger type.
  * If we're testing for (in)equality, and the unsigned value is an integer
    constant whose sign bit is not set, never warn, because even though the
    signed value might change, it can't affect the result of the equality.

Also make the comparison test cases much more rigorous, and have them expose
the subtle differences between C and C++ here.

Douglas Gregor 3ec1bf240d Fixed two places where we needed to force completion of a type
(without complaining if it fails) to get proper semantics: reference
binding with a derived-to-base conversion and the enumeration of
constructors for user-defined conversions. There are probably more
cases to fix, but my prior attempt at statically ensuring that
complete-type checking always happens failed. Perhaps I'll try again.

With this change, Clang can parse include/llvm/*.h!

Douglas Gregor 5287f091b2 When instantiating a UnaryOperator, allow the resulting expression to
still be dependent or invoke an overloaded operator. Previously, we
only supported builtin operators.

BinaryOperator/CompoundAssignOperator didn't have this issue because
we always built a CXXOperatorCallExpr node, even when name lookup
didn't find any functions to save until instantiation time. Now, that
code builds a BinaryOperator or CompoundAssignOperator rather than a
CXXOperatorCallExpr, to save some space.

John McCall 28a6aeab7e Change our basic strategy for avoiding deprecation warnings when the decl use
appears in a deprecated context.  In the new strategy, we emit the warnings
as usual unless we're currently parsing a declaration, where "declaration" is
restricted to mean a decl group or a few special cases in Objective C.  If
we *are* parsing a declaration, we queue up the deprecation warnings until
the declaration has been completely parsed, and then emit them only if the
decl is not deprecated.
We also standardize the bookkeeping for deprecation so as to avoid special cases.
