Dan Gohman 6e681a5fbe Give NamedRegionTimer an Enabled flag, allowing all its clients to 
switch from this:

  if (TimePassesIsEnabled) {
    NamedRegionTimer T(Name, GroupName);
    do_something();
  } else {
    do_something(); // duplicate the code, this time without a timer!
  }

to this:

  {
    NamedRegionTimer T(Name, GroupName, TimePassesIsEnabled);
    do_something();
  }

Chris Lattner 90fe73dc92 finally, maintain a global list of timer groups, allowing us to 
implement TimerGroup::printAll, which prints and resets all active
timers.

llvm-svn: 99876
 2010-03-30 05:27:58 +00:00
Chris Lattner 4cd6571fef add a new TimerGroup::print method, and refactor away the bogus 
TimerGroup copy ctor and assignment operator.

Chris Lattner 6cbd8d118e rename GetLibSupportInfoOutputFile -> CreateInfoOutputFile and 
have it always return a new stream to simplify clients.

Chris Lattner 9a608d248e change TimerGroup to keep a linked list of active timers 
instead of just a count of them, and refactor the guts of
report printing out of removeTimer into its own method.
Refactor addTimerToPrint away.

Chris Lattner 707431cf26 reapply my timer rewrite with a change for PassManager to store 
timers by pointer instead of by-value.

Chris Lattner 09a4074869 remove support for per-time peak memory tracking, this 
isn't used by anyone and is better exposed as a non-per-timer 
thing.  Also, stop including System/Mutex.h in Timer.h

llvm-svn: 99841
 2010-03-29 21:28:41 +00:00
Chris Lattner b355db7877 various timer fixes: move operator= out of line, 
eliminate the per-timer lock (timers should be 
externally locked if needed), the info-output-stream
can never be dbgs(), so drop the check.  Make some
stuff private.

Owen Anderson e9b1beb543 Make timers threadsafe again. This isn't quite as nice as I'd hoped (it uses locking rather than atomic arithmetic), 
but should work on all the platforms we care about.

I might revisit this if a totally awesome way to do it occurs to me.

Owen Anderson 5cc4131063 Revert my last series of commits related to Timer and 64-bit atomics. Not all the targets 
we care about are capable of supporting it.

Owen Anderson ddf74dc986 Actually, these need to be signed integers, not unsigned. 
llvm-svn: 73978
 2009-06-23 18:21:13 +00:00
Owen Anderson bf45b3e2ad Use 64-bit integer counters for tracking time, rather than doubles. This will be more atomic op friendly.

Dan Gohman adec96f438 Reapply 53476 and 53480, with a fix so that it properly updates 
the BB member to the current basic block after emitting
instructions.

Evan Cheng ef8412c822 Back out 53476 and 53480 for now. Somehow they cause llc to miscompile 179.art. 
llvm-svn: 53502
 2008-07-12 01:38:51 +00:00
Dan Gohman 36a69373dc Add support for putting NamedRegionTimers in TimerGroups, and 
use a timer group for the timers in SelectionDAGISel. Also,
Split scheduling out from emitting, to give each their own
timer.

llvm-svn: 53476
 2008-07-11 21:54:34 +00:00
Dan Gohman 3707f1daba Use find instead of lower_bound. 
llvm-svn: 53474
 2008-07-11 20:58:19 +00:00
Dan Gohman 5ceb8b676c Append to the ActiveTimers std::vector before looking at the timer instead 
of after, so that any reallocation it does doesn't get counted for the pass
being timed.  This probably doesn't account for a timing discrepancy I was
looking into, but I'm fixing it anyway.

Chris Lattner 24922c7a2b Timers SHOULD NOT record the time taken to count the bytes allocated in the heap! 
llvm-svn: 20765
 2005-03-22 03:20:38 +00:00
Chris Lattner 610ce2c678 Don't print a 'Total Execution Time' line for the 'Miscellaneous Ungrouped 
Timers' section.  Since these are random timers in the program it doesn't
make sense to sum them up.

Chris Lattner 2295d0b7de Memory used is a delta between memuse at the start of the time and the 
memuse at the end, thus it is signed.

Jeff Cohen 1a26d15c80 Use size_t instead of long to represent memory usage. long is 32 bits

Reid Spencer ad7bdf7400 Fix a bug that made the nightly tester *really* slow. During changes for 
portability, the --track-space option was inadvertently ignored. This patch
fixes that so that sys::Process::GetMallocUsage() is only invoked if the
--track-spaces option is given. Apparently the mallinfo() call that
GetMallocUsage() uses is *very* slow, especially when processing very large
modules like projects/llvm-test/MultiSource/Applications/kimwitu++.
