There should be no change in the output of the '+RTS -s' (summary) report, or the 'RTS -t' (one-line) report. All data shown in the summary report is now shown in the machine readable report. All data in RTSStats is now shown in the machine readable report. init times are added to RTSStats and added to GHC.Stats. Example of the new output: ``` [("bytes allocated", "375016384") ,("num_GCs", "113") ,("average_bytes_used", "148348") ,("max_bytes_used", "206552") ,("num_byte_usage_samples", "2") ,("peak_megabytes_allocated", "6") ,("init_cpu_seconds", "0.001642") ,("init_wall_seconds", "0.001027") ,("mut_cpu_seconds", "3.020166") ,("mut_wall_seconds", "0.757244") ,("GC_cpu_seconds", "0.037750") ,("GC_wall_seconds", "0.009569") ,("exit_cpu_seconds", "0.000890") ,("exit_wall_seconds", "0.002551") ,("total_cpu_seconds", "3.060452") ,("total_wall_seconds", "0.770395") ,("major_gcs", "2") ,("allocated_bytes", "375016384") ,("max_live_bytes", "206552") ,("max_large_objects_bytes", "159344") ,("max_compact_bytes", "0") ,("max_slop_bytes", "59688") ,("max_mem_in_use_bytes", "6291456") ,("cumulative_live_bytes", "296696") ,("copied_bytes", "541024") ,("par_copied_bytes", "493976") ,("cumulative_par_max_copied_bytes", "104104") ,("cumulative_par_balanced_copied_bytes", "274456") ,("fragmentation_bytes", "2112") ,("alloc_rate", "124170795") ,("productivity_cpu_percent", "0.986838") ,("productivity_wall_percent", "0.982935") ,("bound_task_count", "1") ,("sparks_count", "5836258") ,("sparks_converted", "237") ,("sparks_overflowed", "1990408") ,("sparks_dud ", "0") ,("sparks_gcd", "3455553") ,("sparks_fizzled", "390060") ,("work_balance", "0.555606") ,("n_capabilities", "4") ,("task_count", "10") ,("peak_worker_count", "9") ,("worker_count", "9") ,("gc_alloc_block_sync_spin", "162") ,("gc_alloc_block_sync_yield", "0") ,("gc_alloc_block_sync_spin", "162") ,("gc_spin_spin", "18840855") ,("gc_spin_yield", "10355") ,("mut_spin_spin", "70331392") ,("mut_spin_yield", "61700") ,("waitForGcThreads_spin", "241") ,("waitForGcThreads_yield", "2797") ,("whitehole_gc_spin", "0") ,("whitehole_lockClosure_spin", "0") ,("whitehole_lockClosure_yield", "0") ,("whitehole_executeMessage_spin", "0") ,("whitehole_threadPaused_spin", "0") ,("any_work", "1667") ,("no_work", "1662") ,("scav_find_work", "1026") ,("gen_0_collections", "111") ,("gen_0_par_collections", "111") ,("gen_0_cpu_seconds", "0.036126") ,("gen_0_wall_seconds", "0.036126") ,("gen_0_max_pause_seconds", "0.036126") ,("gen_0_avg_pause_seconds", "0.000081") ,("gen_0_sync_spin", "21") ,("gen_0_sync_yield", "0") ,("gen_1_collections", "2") ,("gen_1_par_collections", "1") ,("gen_1_cpu_seconds", "0.001624") ,("gen_1_wall_seconds", "0.001624") ,("gen_1_max_pause_seconds", "0.001624") ,("gen_1_avg_pause_seconds", "0.000272") ,("gen_1_sync_spin", "3") ,("gen_1_sync_yield", "0") ] ``` Test Plan: Ensure that one-line and summary reports are unchanged.
