Hans Wennborg cf9bac4bc9 Warn about missing parentheses for conditional operator.
Warn in cases such as "x + someCondition ? 42 : 0;",
where the condition expression looks arithmetic, and has
a right-hand side that looks boolean.

This (partly) addresses http://llvm.org/bugs/show_bug.cgi?id=9969

Hans Wennborg 0bb0df5839 Make -Wignored-qualifiers point to the first ignored qualifier.
In code such as "char* volatile const j()", Clang warns that "volatile
const" will be ignored. Make it point to the first ignored qualifier,
and simplify the code a bit.

Douglas Gregor 28de7a9a1e Improve the instantiation of static data members in

Chandler Carruth ac6872655b Clean up the "non-POD memaccess" stuff some. This adds a properly named
diagnostic group to cover the cases where we have definitively bad
behavior: dynamic classes.

It also rips out the existing support for POD-based checking. This
didn't work well, and triggered too many false positives. I'm looking
into a possibly more principled way to warn on the fundamental buggy
construct here. POD-ness isn't the critical aspect anyways, so a clean
slate is better. This also removes some silliness from the code until
the new checks arrive.

Douglas Gregor 57d4f972b7 When performing template argument deduction given a function argument
of incomplete array type, attempt to complete the array type. This was
made much easier by Chandler's addition of RequireCompleteExprType(),
which I've tweaked (slightly) to improve the consistency of the
DeclRefExpr. Fixes PR7985.

Douglas Gregor 2f157c9ae2 When checking the instantiation of a default template argument against
the template parameter, perform the checking as a "specified" template
argument rather than a "deduced" template argument; the latter implies
stricter type checking that is not permitted for default template
arguments.

Also, cleanup our handling of substitution of explicit template
arguments for a function template. We were actually performing some
substitution of default arguments at this point!

Fixes PR10069.

Manuel Klimek 0cfc6a045c This patch implements an AST matching framework that allows to write
tools that match on the C++ ASTs. The main interface is in ASTMatchers.h,
an example implementation of a tool that removes redundant .c_str() calls
is in the example RemoveCStrCalls.cpp.

Francois Pichet 3fd47df366 For compatibility with MSVC, a friend declaration also act as a forward declaration if the tag name is not already declared. The tag name is declared in the next outermost non record scope.

  B* b;
};
B* global_b;

John McCall 63fb333fa4 Implement a new, much improved version of the cleanup hack. We just need

Douglas Gregor 27d0c44524 Update the jump-scope checker for local variables with initializers,
so that it looks at the initializer of a local variable of class type
(or array thereof) to determine whether it's just an implicit
invocation of the trivial default constructor. Fixes PR10034.

2011-05-27 16:05:29 +00:00
Chandler Carruth 7c430c0ec2 Enhance Clang to start instantiating static data member definitions
within class templates when they are necessary to complete the type of
the member. The canonical example is code like:

  template <typename T> struct S {
    static const int arr[];
    static const int x;
    static int f();
  };

  template <typename T> const int S<T>::arr[] = { 1, 2, 3 };
  template <typename T> const int S<T>::x = sizeof(arr) / sizeof(arr[0]);
  template <typename T> int S<T>::f() { return x; }

  int x = S<int>::f();

We need to instantiate S<T>::arr's definition to pick up its initializer
and complete the array type. This involves new code to specially handle
completing the type of an expression where the type alone is
insufficient. It also requires *updating* the expression with the newly
completed type. Fortunately, all the other infrastructure is already in
Clang to do the instantiation, do the completion, and prune out the
unused bits of code that result from this instantiation.

This addresses the initial bug in PR10001, and will be a step to
fleshing out other cases where we need to work harder to complete an
expression's type. Who knew we still had missing C++03 "features"?
