Aaron Ballman 6288d0648a The returns_nonnull attribute does not require a function prototype because it affects only the return value, not any arguments. In turn, asking for a function or method result type should not require a function prototype either, so getFunctionOrMethodResultType has been relaxed.

Hans Wennborg be4be16be3 Don't suppress warning about dllimport on typedefs etc. in MicrosoftExt mode
It's true the MSVC doesn't warn about dllimport when applied to e.g. a typedef,
but that applies to dllexport too. I'd like us to be consistent, and I think
the right thing to do is to warn.

The original test that came with implementing the old behaviour doesn't provide
a good motivation, and it said it was checking that we're not repoting an *error*,
which is still true since this is just a warning.

There are plenty of tests e.g. in Sema/dllimport.c to check that we do warn
about dllimport on non functions or variables.

Peter Collingbourne 41af7c2fdc Implement the flatten attribute.
This is a GNU attribute that causes calls within the attributed function

Aaron Ballman efe348ec44 DeLesley Hutchins (who wrote the original thread-safety attribute functionality) and I have agreed to start migrating from lock-specific terminology to "capability"-specific terminology. This opens the door for future threading-related analysis passes so that a common nomenclature can be used.
The following attributes have been (silently) deprecated, with their replacements listed:

lockable => capability
exclusive_locks_required => requires_capability
shared_locks_required => requires_shared_capability
locks_excluded => requires_capability

There are no functional changes intended.

Jordan Rose c939907a5a 'nonnull(1)' on a block parameter should apply to the block's argument.
Thanks to r199467, __attribute__((nonnull)) (without arguments) can apply
directly to parameters, instead of being applied to the whole function.
However, the old form of nonnull (with an argument index) could also apply
to the arguments of function and block pointers, and both of these can be
passed as parameters.

Now, if 'nonnull' with an argument is found on a parameter, /and/ the
parameter is a function or block pointer, it is handled the old way.

David Majnemer 4bb0980d96 MS ABI: Add support for #pragma pointers_to_members
Introduce a notion of a 'current representation method' for
pointers-to-members.

When starting out, this is set to 'best case' (representation method is
chosen by examining the class, selecting the smallest representation
that would work given the class definition or lack thereof).

This pragma allows the translation unit to dictate exactly what
representation to use, similar to how the inheritance model keywords
operate.

N.B.  PCH support is forthcoming.

Alp Toker 314cc81b8c Rename getResultType() on function and method declarations to getReturnType()
A return type is the declared or deduced part of the function type specified in
the declaration.

A result type is the (potentially adjusted) type of the value of an expression
that calls the function.

Rule of thumb:

  * Declarations have return types and parameters.
  * Expressions have result types and arguments.

Alp Toker 9cacbabd33 Rename FunctionProtoType accessors from 'arguments' to 'parameters'
Fix a perennial source of confusion in the clang type system: Declarations and
function prototypes have parameters to which arguments are supplied, so calling
these 'arguments' was a stretch even in C mode, let alone C++ where default
arguments, templates and overloading make the distinction important to get
right.

Readability win across the board, especially in the casting, ADL and
overloading implementations which make a lot more sense at a glance now.

Will keep an eye on the builders and update dependent projects shortly.
