2010-05-01Tweaked EmitCall() to permit the caller to provide some metadata to attach ↵David Chisnall
to the call site. Used this in CGObjCGNU to attach metadata about message sends to permit speculative inlining. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102833 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-28Changed signature of GenerateMessageSend() function to pass the ↵David Chisnall
ObjCInterfaceDecl for class messages and removed the boolean IsClassMessage argument, which wasn't used anywhere. Emitted some metadata on message sends to allow a later pass to do some speculative inlining of class methods (GNU runtime). Speculative inlining of instance methods requires type feedback to be useful (work in progress), but for class methods it works quite nicely. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102514 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-27Ensure return from a message to nil is always 0 (GNU runtime).David Chisnall
This works around stack corruption / crashes resulting from PR6944, and also works around people who expect 'what works on my machine' to work everywhere (GCC crashes in a number of cases on SPARC that should now work correctly with clang). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102430 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-26Make the static type of the exception variable in an Objective-CDouglas Gregor
@catch a VarDecl. The dynamic type is still a ParmVarDecl, but that will change soon. No effective functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102341 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-23Improve the AST representation of Objective-C @try/@catch/@finallyDouglas Gregor
statements. Instead of the @try having a single @catch, where all of the @catch's were chained (using an O(n^2) algorithm nonetheless), @try just holds an array of its @catch blocks. The resulting AST is slightly more compact (not important) and better represents the actual language semantics (good). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102221 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-05Standardize the parsing of function type attributes in a way thatJohn McCall
follows (as conservatively as possible) gcc's current behavior: attributes written on return types that don't apply there are applied to the function instead, etc. Only parse CC attributes as type attributes, not as decl attributes; don't accepet noreturn as a decl attribute on ValueDecls, either (it still needs to apply to other decls, like blocks). Consistently consume CC/noreturn information throughout codegen; enforce this by removing their default values in CodeGenTypes::getFunctionInfo(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95436 91177308-0d34-0410-b5e6-96231b3b80d8

constructed, GC flag not set. Please don't try using this yet - the runtime support is still very immature and your code will almost certainly crash if you do. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95222 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-03Numerous changes to selector handling:David Chisnall
- Don't use GlobalAliases with non-0 GEPs (GNU runtime) - this was unsupported and LLVM will be generating errors if you do it soon. This also simplifies the code generated by the GNU runtime a bit. - Make GetSelector() return a constant (GNU runtime), not a load of a store of a constant. - Recognise @selector() expressions as valid static initialisers (as GCC does). - Add methods to GCObjCRuntime to emit selectors as constants (needed for using @selector() expressions as constants. These need implementing for the Mac runtimes - I couldn't figure out how to do this, they seem to require a load. - Store an ObjCMethodDecl in an ObjCSelectorExpr so that we can get at the type information for the selector. This is needed for generating typed selectors from @selector() expressions (as GCC does). Ideally, this information should be stored in the Selector, but that would be an invasive change. We should eventually add checks for common uses of @selector() expressions. Possibly adding an attribute that can be applied to method args providing the types of a selector so, for example, you'd do something like this: - (id)performSelector: __attribute__((selector_types(id, SEL, id)))(SEL) withObject: (id)object; Then, any @selector() expressions passed to the method will be check to ensure that it conforms to this signature. We do this at run time on the GNU runtime already, but it would be nice to do it at compile time on all runtimes. - Made @selector() expressions emit type info if available and the runtime supports it. Someone more familiar with the Mac runtime needs to implement the GetConstantSelector() function in CGObjCMac. This currently just assert()s. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95189 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-27Unique ObjC strings (GNU Runtime); fix for PR6142. Note: Doing this in the ↵David Chisnall
runtime-specific code is a bit ugly. It would be a good idea to hoist all of the string / protocol uniqueing code up into CGObjCRuntime or CodeGenModule and only handle emitting the original versions in the runtime-specific code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94676 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-14Made ObjC method name mangling match GCC (which does it in a stupid and ↵David Chisnall
broken way that can give conflicts on method names containing underscores, but is needed for gdb to work because gdb does not know how to read ObjC class tables and relies on the mangling). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93427 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-24Fix for bug 5691.David Chisnall
This fixes throwing exceptions inside @catch blocks nested inside outer @try blocks and also fixes jumping from an inner @finally to an outer @finally (via any relevant @catch blocks). The code exhibiting this bug was based on code from CGObjCMac. I believe that this bug may still be present on the Mac runtimes, although the test case in the bug contains a few GNUisms and won't compile without some minor tweaks with Apple's libobjc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92117 91177308-0d34-0410-b5e6-96231b3b80d8

Several of the existing methods were identical to their respective specializations, and so have been removed entirely. Several more 'leaf' optimizations were introduced.

2009-08-17Initial patch to support definitions of id and Class from headers in ↵David Chisnall
Objective-C code. This currently breaks test/SemaObjC/id-isa-ref.m and issues some spurious warnings when you attempt to assign a struct objc_class* value to a Class variable. The test case probably should fail as it's written, because without the definition of Class the compiler should not assume struct objc_class* is a valid receiver type, but it's left broken because it would be nice if we could get that passing too for the special case of isa.
