Gordon Henriksen 364caf0e19 Collector is the base class for garbage collection code generators. ... This version enhances the previous patch to add root initialization as discussed here: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20070910/053455.html Collector gives its subclasses control over generic algorithms: unsigned NeededSafePoints; //< Bitmask of required safe points. bool CustomReadBarriers; //< Default is to insert loads. bool CustomWriteBarriers; //< Default is to insert stores. bool CustomRoots; //< Default is to pass through to backend. bool InitRoots; //< If set, roots are nulled during lowering. It also has callbacks which collectors can hook: /// If any of the actions are set to Custom, this is expected to /// be overriden to create a transform to lower those actions to /// LLVM IR. virtual Pass *createCustomLoweringPass() const; /// beginAssembly/finishAssembly - Emit module metadata as /// assembly code. virtual void beginAssembly(Module &M, std::ostream &OS, AsmPrinter &AP, const TargetAsmInfo &TAI) const; virtual void finishAssembly(Module &M, CollectorModuleMetadata &CMM, std::ostream &OS, AsmPrinter &AP, const TargetAsmInfo &TAI) const; Various other independent algorithms could be implemented, but were not necessary for the initial two collectors. Some examples are listed here: http://llvm.org/docs/GarbageCollection.html#collector-algos git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42466 91177308-0d34-0410-b5e6-96231b3b80d8		2007-09-29 02:13:43 +00:00
