Detailed Description

A trace ensemble is a collection of traces selected using the same strategy, for example 'minimum resource height'. There is one trace for every block in the function.

const [protected]

Get an array of processor resource depths for MBB. Indexed by processor resource kind, this array contains the scaled processor resources consumed by all blocks preceding MBB in its trace. It does not include instructions in MBB.

Compare TraceBlockInfo::InstrDepth.

const [protected]

Get an array of processor resource heights for MBB. Indexed by processor resource kind, this array contains the scaled processor resources consumed by this block and all blocks following it in its trace.
