From e88e7d88b9a9876ee040dad96acf3deabebe1fa7 Mon Sep 17 00:00:00 2001 From: Matt Horsnell Date: Fri, 15 Feb 2013 17:40:09 -0500 Subject: o3: fix tick used for renaming and issue with range selection Fixes the tick used from rename: - previously this gathered the tick on leaving rename which was always 1 less than the dispatch. This conflated the decode ticks when back pressure built in the pipeline. - now picks up tick on entry. Added --store_completions flag: - will additionally display the store completion tail in the viewer. - this highlights periods when large numbers of stores are outstanding (>16 LSQ blocking) Allows selection by tick range (previously this caused an infinite loop) --- src/cpu/o3/iew_impl.hh | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'src/cpu/o3/iew_impl.hh') diff --git a/src/cpu/o3/iew_impl.hh b/src/cpu/o3/iew_impl.hh index 4b4f66a1f..5bd5f6ae9 100644 --- a/src/cpu/o3/iew_impl.hh +++ b/src/cpu/o3/iew_impl.hh @@ -56,6 +56,7 @@ #include "debug/Decode.hh" #include "debug/Drain.hh" #include "debug/IEW.hh" +#include "debug/O3PipeView.hh" #include "params/DerivO3CPU.hh" using namespace std; @@ -1611,7 +1612,9 @@ DefaultIEW::updateExeInstStats(DynInstPtr &inst) iewExecutedInsts++; #if TRACING_ON - inst->completeTick = curTick() - inst->fetchTick; + if (DTRACE(O3PipeView)) { + inst->completeTick = curTick() - inst->fetchTick; + } #endif // -- cgit v1.2.3
