Member Function Documentation

handleDDG()

int DDGPass::handleDDG ( DataDependenceGraph &  ddg, SimpleResourceManager &  rm, const TTAMachine::Machine &  targetMachine, int  minCycle = 0, bool  testOnly = false  )

virtual

Handles a given DDG.

Parameters

ddg	DDG to handle
rm	Resource manager that is to be used.
machine	The target machine if any. (NullMachine::instance() if target machine is irrelevant).

Exceptions

In	case handling is unsuccesful for any reason (basicBlock might still get modified).

Reimplemented in BasicBlockScheduler, BF2Scheduler, and BUBasicBlockScheduler.

    // just to avoid warnings -- need to keep the argument names for
    // Doxygen comments ;)
    ddg.nodeCount();
    rm.largestCycle();
    targetMachine.machineTester();
    abortWithError("Should never call this.");
    minCycle++;
    return INT_MAX;
}

Here is the call graph for this function:

handleLoopDDG()

int DDGPass::handleLoopDDG ( DataDependenceGraph &  , SimpleResourceManager &  , const TTAMachine::Machine &  , int  tripCount, SimpleResourceManager *  prologRM = NULL, bool  testOnly = false  )

virtual

For BasicBlockPass to be able to call this method...

Reimplemented in BUBasicBlockScheduler, BasicBlockScheduler, and BF2Scheduler.
