- 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.

to an output file. This way users can both see the output of 'clang' as well as
enable background logging of files that clang encounters problems on.

scan-build now correctly processes path prefixes that contain multiple '+'
characters or other regex control characters.

Need a couple tweaks to RewriteObjCTryStmt(). Need to deal with implicit finally clauses (to make sure objc_exception_try_exit is called). Also fixed a related bug where we need to generate an implicit @catch else clause (to again make sure objc_exception_try_exit is called).

value).
- Added ABIArgInfo::ByVal (mostly supported) and ABIArgInfo::Expand
(asserted out).
- Added classifyArgumentType which currently just uses
ABIArgInfo::Default or ByVal. This nearly matches old behavior, but
we now set ByVal in a few situations we may have left it off before
(on complex, for example).

(1) Additional arguments to variadic methods should have default
promotions applied.
(2) Additional arguments to non-variadic methods were allowed.

no method declaration was found.
- This was allowing arrays to pass "by value" among other things.
Add assert in CodeGen that arguments cannot have array type.

-Scoping in C99 works good for C++ too, remove the C++-specific comments.
If someone thinks that the C++-specific comments are necessary for clarification, let me know and I'll put them back on.

- As a test, enable basic usage for some common x86-32 cases. This
increases our x86-32 compliance (on other targets our compliance
will just be broken in a different way).

type of a call.
Change NeXT runtime to use this instead of trying to bitcasting
internally (which doesn't respect the ABI).
Fix subtle bug, use of ConvertTypeRecursive instead of ConvertType is
bad inside GetFunctionType.

- Added CodeGenTypes::GetFunctionType, taking a CGFunctionInfo.
- Updated Obj-C runtimes to use this instead of rolling the
llvm::FunctionType by hand.
- Killed CodeGenTypes::{ConvertReturnType, DecodeArgumentTypes}.
Add ABIArgInfo class to encapsulate ABI decision of how to lower types
to LLVM.
- Will move to target sometime soon.

- Realized these functions will eventually need access to more data,
moved to CodeGenModule. Eventually they should probably live
together in some other helper class.

CodeGenFunction::ConstructParamAttrList.
- Make ReturnTypeUsesSret static.

It is a subclass of DeclRefExpr and the main difference is that CXXConditionDeclExpr owns the declaration that it references.

The 'control' scope is the 'condition' scope of if/switch/while statements and the scope that contains the for-init-statement and 'condition' of a for statement.
e.g:
if (int x = 0 /*'control' scope*/) {
// x will be regarded as part of this substatement scope.
} else {
// and as part of this substatement scope too.
}

- For the time being this means our emitted code is somewhat worse,
especially for aggregates. This will be fixed.
