| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
