[LLVMdev] timer mem stats not implemented?

[Ryan M. Lefever]

I tried to use the memory tracking features of the LLVM Timer class, and 
  the results were 0 memory used and 0 peak memory.  In particular, I 
called Timer::addPeakMemoryMeasurement() before initializing timers, and 
I called getPeakMem() and getMemUsed().  Are these functions not 
implemented yet?

Thanks,
Ryan
