| | | | | | | pass a previously failing clang test. // rdar://8808439 llvm-svn: 129004
* Fixes a regression caused by my last patch. Fariborz Jahanian2011-04-051-1/+2
| | | | | | | As a result, I had to remove a c++ version of a clang test which requires more scrutiny on my part. llvm-svn: 128950
* Generate atomic api for atomic properties (x86 and x86_64Fariborz Jahanian2011-04-051-8/+59

* Make the property accessor functions that take a ptrdiff_t actually take a ↵David Chisnall2011-03-221-2/+4
| | | | | | ptrdiff_t instead of a long (should have no impact on any sane platforms, but win64 is not sane). llvm-svn: 128104
* The emission of an Objective-C++'s class .cxx_destruct method should beJohn McCall2011-03-221-38/+95

* Use the "undergoes default argument promotion" bit on parameters toJohn McCall2011-03-091-7/+5
| | | | | | | | | | simplify the logic of initializing function parameters so that we don't need both a variable declaration and a type in FunctionArgList. This also means that we need to propagate the CGFunctionInfo down in a lot of places rather than recalculating it from the FAL. There's more we can do to eliminate redundancy here, and I've left FIXMEs behind to do it. llvm-svn: 127314
* DebugInfo can be enabled or disabled at function level (e.g. using an ↵Devang Patel2011-03-071-2/+2
| | | | | | attribute). However, at module level it is determined by command line option and the state of command line option does not change during compilation. Make this layering explicit and fix accidental cases where the code generator was checking whether module has debug info enabled instead of checking whether debug info is enabled for this function or not. llvm-svn: 127165

| | | | | | | | | | | | | | process, perform a number of refactorings: - Move MiscNameMangler member functions to MangleContext - Remove GlobalDecl dependency from MangleContext - Make MangleContext abstract and move Itanium/Microsoft functionality to their own classes/files - Implement ASTContext::createMangleContext and have CodeGen use it No (intended) functionality change. llvm-svn: 123386
* Renamed CXXBaseOrMemberInitializer to CXXCtorInitializer. This is both shorter,Alexis Hunt2011-01-081-3/+3
| | | | | | | more accurate, and makes it make sense for it to hold a delegating constructor call. llvm-svn: 123084
* Rework a few things about how we emit ObjC's for enumeration statement.John McCall2011-01-071-95/+126
| | | | | | | | | | In particular, the iteration variable (if present) should be created and destroyed in a narrow span around the loop body, and the body should be emitted in a cleanup scope in case it's not a compound statement. Otherwise, rename a few variables and use phis instead of temporary variables for the index and buffer count. llvm-svn: 122988
* Add support for GNU runtime property set / get structure functions. Minor ↵David Chisnall2010-12-261-4/+4
| | | | | | refactoring of Mac runtime (returns the same function for both, as the Mac runtimes currently only provide a single entry point for setting and getting struct properties, although this will presumably be fixed at some point). llvm-svn: 122569
* Fix a bug in the emission of __real/__imag l-values on scalar operands.John McCall2010-12-051-2/+1
| | | | | | | | | Fix a bug in the emission of complex compound assignment l-values. Introduce a method to emit an expression whose value isn't relevant. Make that method evaluate its operand as an l-value if it is one. Fixes our volatile compliance in C++. llvm-svn: 120931
* More anonymous struct/union redesign. This one deals with anonymous field ↵Francois Pichet2010-12-041-2/+2
| | | | | | | | | | | | | | | | used in a constructor initializer list: struct X { X() : au_i1(123) {} union { int au_i1; float au_f1; }; }; clang will now deal with au_i1 explicitly as an IndirectFieldDecl. llvm-svn: 120900
* Test case for the l-value base only being evaluated once.John McCall2010-12-041-44/+43
| | | | | | | | | | Also, move the l-value emission code into CGObjC.cpp and teach it, for completeness, to store away self for a super send. Also, inline the super cases for property gets and sets and make them use the correct result type for implicit getter/setter calls. llvm-svn: 120887

* Calculate the value kind of an expression when it's created andJohn McCall2010-11-181-4/+4
| | | | | | | | | | | | | store it on the expression node. Also store an "object kind", which distinguishes ordinary "addressed" l-values (like variable references and pointer dereferences) and bitfield, @property, and vector-component l-values. Currently we're not using these for much, but I aim to switch pretty much everything calculating l-valueness over to them. For now they shouldn't necessarily be trusted. llvm-svn: 119685

* one piece of code is responsible for the lifetime of every aggregateJohn McCall2010-09-151-4/+2
| | | | | | | | | | | | | slot. The easiest way to do that was to bundle up the information we care about for aggregate slots into a new structure which demands that its creators at least consider the question. I could probably be convinced that the ObjC 'needs GC' bit should be rolled into this structure. Implement generalized copy elision. The main obstacle here is that IR-generation must be much more careful about making sure that exactly llvm-svn: 113962

* Store inheritance paths after CastExprs instead of inside them.John McCall2010-08-071-2/+2
| | | | | | | | | | | | | | | This takes some trickery since CastExpr has subclasses (and indeed, is abstract). Also, smoosh the CastKind into the bitfield from Expr. Drops two words of storage from Expr in the common case of expressions which don't need inheritance paths. Avoids a separate allocation and another word of overhead in cases needing inheritance paths. Also has the advantage of not leaking memory, since destructors for AST nodes are never run. llvm-svn: 110507
* Return type of a setter call caused byFariborz Jahanian2010-07-241-1/+1
| | | | | | | | use of property-dot syntax using 'super' as receiver is 'void'. This fixes a bug in generating correct API for setter call. Fixes radar 8203426. llvm-svn: 109297

| | | | | | | | | | | | | | | | | | | | | | | | self-host. Hopefully these results hold up on different platforms. I tried to keep the GNU ObjC runtime happy, but it's hard for me to test. Reimplement how clang generates IR for exceptions. Instead of creating new invoke destinations which sequentially chain to the previous destination, push a more semantic representation of *why* we need the cleanup/catch/filter behavior, then collect that information into a single landing pad upon request. Also reorganizes how normal cleanups (i.e. cleanups triggered by non-exceptional control flow) are generated, since it's actually fairly closely tied in with the former. Remove the need to track which cleanup scope a block is associated with. Document a lot of previously poorly-understood (by me, at least) behavior. The new framework implements the Horrible Hack (tm), which requires every landing pad to have a catch-all so that inlining will work. Clang no longer requires the Horrible Hack just to make exceptions flow correctly within a function, however. The HH is an unfortunate requirement of LLVM's EH IR. llvm-svn: 107631

* Substantially alter the design of the Objective C type AST by introducingJohn McCall2010-05-151-1/+1
| | | | | | | | | | | | | | | | | | | | | ObjCObjectType, which is basically just a pair of one of {primitive-id, primitive-Class, user-defined @class} with a list of protocols. An ObjCObjectPointerType is therefore just a pointer which always points to one of these types (possibly sugared). ObjCInterfaceType is now just a kind of ObjCObjectType which happens to not carry any protocols. Alter a rather large number of use sites to use ObjCObjectType instead of ObjCInterfaceType. Store an ObjCInterfaceType as a pointer on the decl rather than hashing them in a FoldingSet. Remove some number of methods that are no longer used, at least after this patch. By simplifying ObjCObjectPointerType, we are now able to easily remove and apply pointers to Objective-C types, which is crucial for a certain kind of ObjC++ metaprogramming common in WebKit. llvm-svn: 103870
