Usage: dp <index>
Display pipeline state.
<index>: index of shader core you would like to see the pipeline state of
This function displays the state of the pipeline on a single shader core
(setting different values for the first argument of the call to
dump_pipeline will cause different information to be displayed--
see the source code for more details)

document dpc
Usage: dpc <index>
Display pipeline state, then continue to next breakpoint.
<index>: index of shader core you would like to see the pipeline state of
This version is useful if you set a breakpoint where gpu_sim_cycle is
incremented in gpu_sim_loop() in src/gpgpu-sim/gpu-sim.c
repeatly hitting enter will advance to show the pipeline contents on
the next cycle.
