Analysis option -warn-objc-nserror-methods is no longer available. (check is done automatically with -checker-cfref)

Change implementation of NSError** coding-style check to be invoked at the end of the retain/release analysis.

llvm-svn: 56312

Also added a couple simple tests from the "gcc.apple" test suite.

llvm-svn: 56309

Also tweaked the create function to take an explicit output file.

"Method accepting NSError** argument should have non-void return value to indicate that an error occurred."

Test case written, but the header needs to be delta-debugged reduced.  Will commit shortly.

 - Enables use of ABIArgInfo::Expand when needed. This greatly
   improves our x86 ABI compatibility.

 - As the infrastructure for target specific ABI handling isn't built
   yet, this change means ABI compatibility on other platforms is once
   again broken in a different way than before.

 - Upcoming: Figure out how to refactor ABI handling into
   targets. More documentation.

Ensure that ABIArgInfo::Default implementation for aggregrate types
is sensible (StructRet on return and ByVal on arguments).

No functionality change.

Block literals are now represented by the concrete BlockExpr class.
This is cleanup (removes a FIXME).

  if we know that 'len != 0' and know that 'i == 0' then we know that
  'i < len' must evaluate to true and cannot evaluate to false

 ^(expression) or ^(int arg1, float arg2)(expression)
...is no longer supported. 
All block literals now require a compound statement.

Sema::CheckReturnStackAddr(): Make sure we skip over implicit casts.
Added some more test cases...

motivated because it became clear that the number of subclasses of ProgramPoint
would expand and we ran out of bits to represent a pointer variant. As a plus of
this change, BlockEdge program points can now be represented explicitly without
using a cache of CFGBlock* pairs in CFG.

 - For investigating warnings in system headers / builtins.
 - Currently also enables the behavior that allows silent redefinition
   of types in system headers. Conceptually these are separate but I
   didn't feel it was worth two options (or changing LangOptions).

Give string literals const element typesin C++, and cope with the deprecated C++ conversion from a string literal to a pointer-to-non-const-character

llvm-svn: 56137

 - Follow C99 behavior of using other operand type when one of
   operands is a null pointer constant.
 - Fix overenthusiastic devolving of any Objective-C types to id:
   o If either operand has an Objective-C object type then:
     - If both operands are interfaces and either operand can be
       assigned to the other, use that type as the composite type.
     - Otherwise, if either type is id, use id as the composite type.
     - Otherwise, warn about incompatible types and use id as the
       composite type.
 - Return handling of qualified idea to separate test following
   general pointer type checking.
   o Upgraded from old code to allow devolving to id (without warning,
     which matches GCC).
 - <rdar://problem/6212771>

Add test case for issues fixed above, XFAIL though because it exposed
a new issue in property handling.

Add comments about C++ clause 3.3.2p4 that mentions that the condition declaration should be local to an if/switch/while/for statement.
