Classes
class Ensemble
A trace ensemble is a collection of traces selected using the same strategy, for example 'minimum resource height'. More...
struct FixedBlockInfo
Per-basic block information that doesn't depend on the trace through the block. More...
struct InstrCycles
InstrCycles represents the cycle height and depth of an instruction in a trace. More...
struct LiveInReg
A virtual register or regunit required by a basic block or its trace successors. More...
class Trace
A trace represents a plausible sequence of executed basic blocks that passes through the current basic block one. More...
struct TraceBlockInfo
Per-basic block information that relates to a specific trace through the block. More...
