2009-05-27Convert ObjC qualified type clients over to using iterators.Steve Naroff
This allows me to remove some API that I don't want to carry over to ObjCObjectPointerType. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72475 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-14Don't warn if result/argument type of an implemented Fariborz Jahanian
method is a qualified id which conforms to the matching type of its method declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71817 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-13Some early declarations to support sentinel attribute onFariborz Jahanian
message dispatches (and function calls later). No change in functionality. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71683 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-08We want to diagnose sending message to a forward classFariborz Jahanian
and we also want to tell which message is actually being sent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71296 91177308-0d34-0410-b5e6-96231b3b80d8

in a 'Class' receiver which is not a root instance method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70987 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-29fix PR4021, array and functions decay in the receiver position of an objc ↵Chris Lattner
message send. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70373 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-24PCH support for the global method pool (= instance and factory methodDouglas Gregor
pools, combined). The methods in the global method pool are lazily loaded from an on-disk hash table when Sema looks into its version of the hash tables. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69989 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-24Eliminate Sema::ObjCImplementations, relying instead on name lookup. What's ↵Douglas Gregor
good for uniformity is good for PCH (or is it the other way around?). As part of this, make ObjCImplDecl inherit from NamedDecl (since ObjCImplementationDecls now need to have names so that they can be found). This brings ObjCImplDecl very, very close to ObjCContainerDecl; we may be able to merge them soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69941 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23Eliminate Sema::ObjCProtocols. Instead, we place ObjCProtocolDecls inDouglas Gregor
their own namespace (IDNS_Protocol) and use the normal name-lookup routines to find them. Aside from the simplification this provides (one less DenseMap!), it means that protocols will be lazily deserialized from PCH files. Make the code size of the selector table block match the code size of the type and decl blocks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69939 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23Eliminate the three SmallVectors in ObjCImplDecl (for instanceDouglas Gregor
methods, class methods, and property implementations) and instead place all of these entities into the DeclContext. This eliminates more linear walks when looking for class or instance methods and should make PCH (de-)serialization of ObjCDecls trivial (and lazy). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69849 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-12Fix rdar://6770142 - Class and qualified id's are compatible, just likeChris Lattner
Class and unqualified id's are. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68899 91177308-0d34-0410-b5e6-96231b3b80d8

crashes codegen. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68891 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-09Propagate the ASTContext to various AST traversal and lookup functions.Douglas Gregor
No functionality change (really). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68726 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Tweak Sema::ActOnInstanceMessage() to look for a class method when dealing ↵Steve Naroff
with qualified id's. This change is motivated by our desire to not support the "Class<foo>" idiom. Note that the change makes perfect sense (since all ObjC classes are also id/instances). This allow us to document a simple migration path...change "Class <foo>" to "id <foo>". This effects: - <rdar://problem/6761939> TASK: File source change radars for "qualified Class" errors - <rdar://problem/6761864> Protocol qualified Class is unsupported git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68517 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Change the type of ObjC @ string constants (from NSConstantString->NSString).Steve Naroff
This fixes <rdar://problem/6757102> clang type for @"xxx" is "NSConstantString *" (GCC type is "NSString *"). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68514 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-09Fix PR3766, a really nasty silent miscompilation case where we emittedChris Lattner
a warning and then threw away the AST. While I'm in there, tighten up the code to actually reject completely bogus cases (sending a message to a struct). We still allow sending a message to an int, which doesn't make sense but GCC allows it and is easy to support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66468 91177308-0d34-0410-b5e6-96231b3b80d8

If all else failed, find the message in class's root's list of instacne methods! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66040 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Finish up some fixes related to <rdar://problem/6497631> Message lookup is ↵Steve Naroff
sometimes different than gcc's. - Disallow casting 'super'. GCC allows this, however it doesn't make sense (super isn't an expression and the cast won't alter lookup/dispatch). - Tighten up lookup when messaging 'self'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66033 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-03Implement an important missing warning when a selectorFariborz Jahanian
is searched for in the global pool. It already uncovered a clang bug in message selection. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65974 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-03Fix <rdar://problem/6497242> Inherited overridden protocol declared objects ↵Steve Naroff
don't work. Change Sema::DiagnosePropertyMismatch() to check for type compatibility (rather than type equivalence, which is too strict). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65949 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-26Fix <rdar://problem/6614945> method not found. Steve Naroff
This was a fairly recent regression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65547 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-26Fix http://llvm.org/bugs/show_bug.cgi?id=3544.Steve Naroff
The code for looking up local/private method in Sema::ActOnInstanceMessage() was not handling categories properly. Sema::ActOnClassMessage() didn't have this bug. Created a helper with the correct logic and changed both methods to use it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65532 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24first wave of fixes for @encode sema support. This is part of PR3648.Chris Lattner
The big difference here is that (like string literal) @encode has array type, not pointer type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65391 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-23Remove isSuperExpr(), which ignores any casts on 'super'.Steve Naroff
I don't think casting super makes any sense (since it won't effect method lookup). Will discuss with other offline and decide what to do. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65317 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-22Contains the following (related to problems found while investigting ↵Steve Naroff
<rdar://problem/6497631> Message lookup is sometimes different than gcc's). - Implement instance/class overloading in ObjCContainerDecl (removing a FIXME). This involved hacking NamedDecl::declarationReplaces(), which took awhile to figure out (didn't realize replace was the default). - Changed Sema::ActOnInstanceMessage() to remove redundant warnings when dealing with protocols. For now, I've omitted the "protocol" term in the diagnostic. It simplifies the code flow and wan't always 100% accurate (e.g. "Foo<Prot>" looks in the class interface, not just the protocol). - Changed several test cases to jive with the above changes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65292 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-21More work to integrate newly added ObjCQualifiedClassType into the type system.Steve Naroff
This is necessary 'plumbing' to fix <rdar://problem/6497631> Message lookup is sometimes different than gcc's. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65248 91177308-0d34-0410-b5e6-96231b3b80d8

interfaces more consistently. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65138 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-18Downgrade complaints about calling unavailable functions to a warningDouglas Gregor
(as GCC does), except when we've performed overload resolution and found an unavailable function: in this case, we actually error. Merge the checking of unavailable functions with the checking for deprecated functions. This unifies a bit of code, and makes sure that we're checking for unavailable functions in the right places. Also, this check can cause an error. We may, eventually, want an option to make "unavailable" warnings into errors. Implement much of the logic needed for C++0x deleted functions, which are effectively the same as "unavailable" functions (but always cause an error when referenced). However, we don't have the syntax to specify deleted functions yet :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64955 91177308-0d34-0410-b5e6-96231b3b80d8
