* Collector is the base class for garbage collection code generators.Gordon Henriksen2007-09-292-0/+391
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 llvm-svn: 42466

* If two instructions are both two-address code, favors (schedule closer toEvan Cheng2007-09-282-8/+25

* TargetAsmInfo::getAddressSize() was incorrect for x86-64 and 64-bit targetsDan Gohman2007-09-271-15/+16
| | | | | | | | other than PPC64. Instead of fixing it, just remove it and fix all the places that use it to use TargetData::getPointerSize() instead, as there aren't very many. Most of the references were in DwarfWriter.cpp. llvm-svn: 42419
* CollectorMetadata abstractly describes stack maps for a function.Gordon Henriksen2007-09-271-0/+185
| | | | | | | | | | | | | | | | | | | | It includes: - location and of each safe point in machine code (identified by a label) - location of each root within the stack frame (identified by an offset), including the metadata tag provided to llvm.gcroot in the user program - size of the stack frame (for collectors which want to cheat on stack crawling :) - and eventually will include liveness It is to be populated by back-ends during code-generation. CollectorModuleMetadata aggregates this information across the entire module. llvm-svn: 42418

* Added major new capabilities to scheduler (only BURR for now) to support ↵Evan Cheng2007-09-255-150/+559
| | | | | | physical register dependency. The BURR scheduler can now backtrace and duplicate instructions in order to avoid "expensive / impossible to copy" values (e.g. status flag EFLAGS for x86) from being clobbered. llvm-svn: 42284
* Don't emit .debug_line header data if there aren't any lines to put in it,Dan Gohman2007-09-241-0/+5
| | | | | | such as will happen when .loc directives are used. llvm-svn: 42277

* Change APFloat::convertFromInteger to take the incomingDale Johannesen2007-09-212-3/+6
| | | | | | | | | | bit width instead of number of words allocated, which makes it actually work for int->APF conversions. Adjust callers. Add const to one of the APInt constructors to prevent surprising match when called with const argument. llvm-svn: 42210
