| # This script is used to dump ASCII traces of the instruction dependency |
| # graph to protobuf format. |
| # |
| # The ASCII trace format uses one line per instruction with the format |
| # instruction sequence number, (optional) pc, (optional) weight, type, |
| # (optional) flags, (optional) physical addr, (optional) size, comp delay, |
| # (repeated) order dependencies comma-separated, and (repeated) register |
| # dependencies comma-separated. |
| # |
| # examples: |
| # seq_num,[pc],[weight,]type,[p_addr,size,flags,]comp_delay:[rob_dep]: |
| # [reg_dep] |
