2011-09-09Clean up the sentinel-attribute checking code a lot. DocumentJohn McCall
what 'nullPos' is supposed to mean, at least at this one site. Use closed forms for the arithmetic. Rip out some clever but ultimately pointless code that was trying to use 0 or 0L depending the size of a pointer vs. the size of int; first, it didn't work on LLP64 systems, and second, the sentinel checking code requires a pointer-typed value anyway, so this fixit would not have actually removed the warning. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139361 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-09Do a lookup for the blocks runtime globals to see if they were declared,Argyrios Kyrtzidis
instead of codegen waiting to consume such a declaration, which won't happen if that decls are coming from a PCH. Fixes rdar://10028656. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139359 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-09Contextually converting to 'id' is not a useful operation. ContextuallyJohn McCall
converting to an arbitrary Objective-C pointer type is. Without significantly re-implementing anything, change the API to reflect this, and as a minor optimization, strip the pointer conversion off before potentially building it. Mostly, this removes a really bizarre-looking bit of code from BuildInstanceMessage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139354 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-09Give conversions of block pointers to ObjC pointers a different cast kindJohn McCall
than conversions of C pointers to ObjC pointers. In order to ensure that we've caught every case, add asserts to CastExpr that strictly determine which cast kind is used for which kind of bit cast. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139352 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-08Implement the Objective-C 'instancetype' type, which is an alias ofDouglas Gregor
'id' that can be used (only!) via a contextual keyword as the result type of an Objective-C message send. 'instancetype' then gives the method a related result type, which we have already been inferring for a variety of methods (new, alloc, init, self, retain).

2011-09-07Optimize the preprocessor's handling of the __import_module__Douglas Gregor
keyword. We now handle this keyword in HandleIdentifier, making a note for ourselves when we've seen the __import_module__ keyword so that the next lexed token can trigger a module import (if needed). This greatly simplifies Preprocessor::Lex(), and completely erases the 5.5% -Eonly slowdown Argiris noted when I originally implemented __import_module__.

2011-09-07Extract the emission of the diagnostic's location into a separateChandler Carruth
function. This is really the beginning of the second phase of refactorings here. The end goal is to have (roughly) three interfaces: 1) Base class to format a single diagnostic suitable for display on the console. 2) Extension of the base class which also displays a caret diagnostic suitable for display on the console. 3) An adaptor that implements the DiagnosticClient by delegating to #1 and/or #2 as appropriate. Once we have these, things like libclang's formatDiagnostic can use #1 and #2 to provide really well formatted (and consistently formatted!) textual formatting of diagnostics. Getting there is going to be quite a bit of shuffling. I'm basically sketching out where the interface boundaries can be drawn for #1 and #2 within the existing classes. That lets me shuffle with a minimum of fuss and delta. Once that's done, and any of the related interfaces that need to change are updated, I'll hoist these into separate headers and re-implement libclang in terms of their interfaces. Long WIP, but comments at each step welcome. =D git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139228 91177308-0d34-0410-b5e6-96231b3b80d8
