Hi all, I suggest new patch from the series Igor introdusced. 1. To move direct predicated calls in separete node. It allows to have under predicate short branch instruction instead of call and thus reduce possible misprediction penalty. 2. I have implemented new node merging algorithm. It is more effective than previouc one and besides purging empty nodes.
All changes made in Code layouting and I suggest integrate them in one patch. Thank you, Konstantin "Igor Chebykin" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] Hello all, I suggest a short series of patches for drlvm ipf code generator. We have some improvements for jitrino/ipf and would like to commit its to harmony. All patches will change only vm/jitrino/src/codegenerator/ipf/* files, therefore ia32 remains OK. The first patch is about 67k size and contains following files: IpfCfg.h, IpfCfg.cpp methods added in Edge and Node classes IpfCodeLayouter.h, IpfCodeLayouter.cpp new BotomUp algorithm implementation IpfEmitter.h, IpfEmitter.cpp minor changes in logging, Emitter::registerDirectCall() and debugging support IpfIrPrinter.h, IpfIrPrinter.cpp added method to print Node chains IpfType.h types to support Node chains added IpfCfgVerifier.cpp method cfg.getArgs() deprecated IpfInst.cpp methods to identify inst kind added (isBr, isCall ) IpfRegisterAllocator.cpp minor changes in logging Thanks, Igor. -- Igor Chebykin, Intel Middleware Products Division --------------------------------------------------------------------- Terms of use : http://incubator.apache.org/harmony/mailing.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
