8 years agoDon't require nullability on template parameters in typedefs.
Jordan Rose [Wed, 2 Nov 2016 20:44:07 +0000 (20:44 +0000)]
Don't require nullability on template parameters in typedefs.

Previously the following code would warn on the use of "T":

  template <typename T>
  struct X {
    typedef T *type;
  };

...because nullability is /allowed/ on template parameters (because
they could be pointers). (Actually putting nullability on this use of
'T' will of course break if the argument is a non-pointer type.)

This fix doesn't handle the case where a template parameter is used
/outside/ of a typedef. That seems trickier, especially in parameter
position.

When using in-tree builds, HAVE_LIBZ is declared in
cmake/config-ix.cmake as a result of LLVM's CMake checks. When building
stand-alone, this value is not available and as a result caused clang to
wrongly assume that LLVM was built without zlib support.

To fix it, set it to the value of LLVM_ENABLE_ZLIB. While this variable
is originally used to control the user preference, LLVM updates its
value to 0 if zlib checks fail. Therefore, we can use it to reliably

8 years agoA compound literal within a global lambda or block is still within
John McCall [Mon, 31 Oct 2016 21:56:26 +0000 (21:56 +0000)]
A compound literal within a global lambda or block is still within
the body of a function for the purposes of computing its storage
duration and deciding whether its initializer must be constant.

There are a number of problems in our current treatment of compound
literals.  C specifies that a compound literal yields an l-value
referring to an object with either static or automatic storage
duration, depending on where it was written; in the latter case,
the literal object has a lifetime tied to the enclosing scope (much
like an ObjC block), not the enclosing full-expression.  To get these
semantics fully correct in our current design, we would need to
collect compound literals on the ExprWithCleanups, just like we do
with ObjC blocks; we would probably also want to identify literals
like we do with materialized temporaries.  But it gets stranger;
GCC adds compound literals to C++ as an extension, but makes them
r-values, which are generally assumed to have temporary storage
duration.  Ignoring destructor ordering, the difference only matters
if the object's address escapes the full-expression, which for an
r-value can only happen with reference binding (which extends
temporaries) or array-to-pointer decay (which does not).  GCC then
attempts to lock down on array-to-pointer decay in ad hoc ways.
Arguably a far superior language solution for C++ (and perhaps even
array r-values in C, which can occur in other ways) would be to
propagate lifetime extension through array-to-pointer decay, so
that initializing a pointer object to a decayed r-value array
extends the lifetime of the complete object containing the array.
But this would be a major change in semantics which arguably ought
to be blessed by the committee(s).

Anyway, I'm not fixing any of that in this patch; I did try, but
it got out of hand.

Fixes rdar://28949016.

[CUDA] [AST] Allow isInlineDefinitionExternallyVisible to be called on functions without bodies.

Summary:
In CUDA compilation, we call isInlineDefinitionExternallyVisible (via
getGVALinkageForFunction) on functions while parsing their definitions.

At the point in time when we call getGVALinkageForFunction, we haven't
yet added the body to the function, so we trip this assert.  But as far
as I can tell, this is harmless.

There was other code that was working around the existing assert with a
really awful hack -- this change lets us get rid of that hack.

objc_subclassing_restricted but don't have @implementation are allowed to
inherit other @interface declarations with objc_subclassing_restricted. This is
needed to describe the Swift class hierarchy in clang while making sure that
the Objective-C classes cannot subclass the Swift classes.

(https://github.com/apple/swift-clang) and this patch moves that code to the
upstream clang repository.
