From c1e58b6bf6b353f9355aafd8ed2cb86e6d00e32a Mon Sep 17 00:00:00 2001 From: Steve Reinhardt Date: Mon, 21 Jun 2004 22:42:16 -0700 Subject: [PATCH] Handle SIGABRT a little more nicely. base/misc.cc: Don't dump trace in panic(), SIGABRT handler will do it now. sim/main.cc: Add SIGABRT handler that prints curTick and dumps buffered trace (if any). This doesn't work as well as I would like since the buffered trace records often contain stale references to stack-resident temporary std::string objects. Someday we'll have to put in a fix for that. --HG-- extra : convert_revision : 67576efbf5c10e63e255fc9a9ec520326fd3567b --- base/misc.cc | 5 ----- sim/main.cc | 13 +++++++++++++ 2 files changed, 13 insertions(+), 5 deletions(-) diff --git a/base/misc.cc b/base/misc.cc index 5caf96d40..1304fb128 100644 --- a/base/misc.cc +++ b/base/misc.cc @@ -61,11 +61,6 @@ __panic(const string &format, cp::ArgList &args, const char *func, delete &args; -#if TRACING_ON - // dump trace buffer, if there is one - Trace::theLog.dump(cerr); -#endif - abort(); } diff --git a/sim/main.cc b/sim/main.cc index 032a05668..c990d830b 100644 --- a/sim/main.cc +++ b/sim/main.cc @@ -90,6 +90,18 @@ exitNowHandler(int sigtype) async_exit = true; } +/// Abort signal handler. +void +abortHandler(int sigtype) +{ + cerr << "Program aborted at cycle " << curTick << endl; + +#if TRACING_ON + // dump trace buffer, if there is one + Trace::theLog.dump(cerr); +#endif +} + /// Simulator executable name const char *myProgName = ""; @@ -232,6 +244,7 @@ main(int argc, char **argv) signal(SIGUSR1, dumpStatsHandler); // dump intermediate stats signal(SIGUSR2, dumprstStatsHandler); // dump and reset stats signal(SIGINT, exitNowHandler); // dump final stats and exit + signal(SIGABRT, abortHandler); sayHello(cerr); -- 2.30.2
