Member Data Documentation

execSeqNum

InstSeqNum gem5::minor::InstId::execSeqNum

'Execute' sequence number.

These are assigned after micro-op decomposition and form an ascending sequence (starting with 1) for post-micro-op decomposed instructions.

Definition at line 110 of file dyn_inst.hh.

Referenced by operator==().

fetchSeqNum

InstSeqNum gem5::minor::InstId::fetchSeqNum

Fetch sequence number.

This is 0 for bubbles and an ascending sequence for the stream of all fetched instructions

Definition at line 105 of file dyn_inst.hh.

Referenced by operator==().

firstExecSeqNum

const InstSeqNum gem5::minor::InstId::firstExecSeqNum = 1

firstLineSeqNum

const InstSeqNum gem5::minor::InstId::firstLineSeqNum = 1

firstPredictionSeqNum

const InstSeqNum gem5::minor::InstId::firstPredictionSeqNum = 1

static

Definition at line 81 of file dyn_inst.hh.

firstStreamSeqNum

const InstSeqNum gem5::minor::InstId::firstStreamSeqNum = 1

static

First sequence numbers to use in initialisation of the pipeline and to be expected on the first line/instruction issued.

Definition at line 80 of file dyn_inst.hh.

lineSeqNum

InstSeqNum gem5::minor::InstId::lineSeqNum

Line sequence number.

This is the sequence number of the fetched line from which this instruction was fetched

Definition at line 101 of file dyn_inst.hh.

Referenced by operator==().

predictionSeqNum

InstSeqNum gem5::minor::InstId::predictionSeqNum

The predicted qualifier to stream, attached by Fetch2 as a consequence of branch prediction.

Definition at line 97 of file dyn_inst.hh.

Referenced by gem5::minor::Fetch2::evaluate(), and operator==().

streamSeqNum

InstSeqNum gem5::minor::InstId::streamSeqNum

The 'stream' this instruction belongs to.

Streams are interrupted (and sequence numbers increased) when Execute finds it wants to change the stream of instructions due to a branch.

Definition at line 93 of file dyn_inst.hh.

Referenced by gem5::minor::Fetch2::evaluate(), and operator==().

threadId

ThreadID gem5::minor::InstId::threadId

The thread to which this line/instruction belongs.

Definition at line 88 of file dyn_inst.hh.

Referenced by gem5::minor::Fetch1::evaluate(), gem5::minor::Fetch2::evaluate(), gem5::minor::Fetch1::fetchLine(), operator==(), and gem5::minor::Fetch1::processResponse().
