* This remat entry is basically done. There are hooks to allow targetsDan Gohman2009-10-141-38/+0
| | | | | | | | | to remat non-load instructions as loads, and the remat code now uses the UnmodeledSideEffects flags, MachineMemOperands, and similar things to decide which instructions are valid for rematerialization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84060 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | up to the various compiler pipelines. This doesn't actually add support for any GC algorithms, which means it temporarily breaks a few tests. To be fixed shortly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45669 91177308-0d34-0410-b5e6-96231b3b80d8

* Collector is the base class for garbage collection code generators.Gordon Henriksen2007-09-291-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
