# 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]:
