if we can see the elements of the arrays.
for example:
NSDictionary *dict = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"1", @"2", nil] forKeys:[NSArray arrayWithObjects:@"A", @"B", nil]];
-->
NSDictionary *dict = @{ @"A" : @"1", @"B" : @"2" };

This change was initially proposed as a solution to the problem highlighted by check-in r164677, i.e. that -verify will not cause a test-case failure where the compile command does not actually reference the file.
Patch reviewed by David Blaikie.
llvm-svn: 166281
The old behavior was to re-scan any files (like modules) where we may have
directives but won't actually be parsing during the -verify invocation.
Now, we keep the old behavior in Debug builds as a sanity check (though
modules are a known entity), and expect all legitimate directives to come
from comments seen by the preprocessor.
This also affects the ARC migration tool, which captures diagnostics in
order to filter some out. This change adds an explicit cleanup to
CaptureDiagnosticsConsumer in order to let its sub-consumer handle the
real end of diagnostics.
This was originally split into four patches, but the tests do not run
cleanly without all four, so I've combined them into one commit.

type of generated call to super dealloc is 'void'
and asserts if user's dealloc is not of 'void type.
This rule must be enforced in clang front-end (with a
fixit) if this is not the case, instead of asserting in CodeGen.

that the migrator handles) but return their instances as 'id', resulting
in the compiler resolving 'objectForKey:' as the method from NSDictionary.
When checking if we can convert to subscripting syntax, check whether
the receiver is a result of a class method from a hardcoded list of
such classes. In such a case return the specific class as the interface
of the receiver.

This is way better to fully understand the warning.

This is more trouble that it is worth; autoreleasing a value without holding on it
is a valid use-case, we should not "punish" correct code for the minority of
broken/fragile programs that depend on the behavior of -autorelease.

There are some caveats:
-If an implicit cast (e.g. int -> float for numberWithFloat:) was required, the message
will not get rewritten
-If the message was with numberWithInteger:/numberWithUnsignedInteger:, which are very
commonly used, be more liberal and allow the boxing syntax if the underlying type has
same signedness and will not lose precision.

the new Objective-C NSArray/NSDictionary/NSNumber literal syntax.
This introduces a new library, libEdit, which provides a new way to support
migration of code that improves on the original ARC migrator. We now believe
that most of its functionality can be refactored into the existing libraries,
and thus this new library may shortly disappear.
