[llvm-commits] CVS: reopt/lib/LightWtProfiling/Initialization.cpp

[Brian Gaeke]

Changes in directory reopt/lib/LightWtProfiling:

Initialization.cpp updated: 1.11 -> 1.12

---
Log message:

Include scheduler.h, for initialize_timer().

Define timer_interval_sec, timer_interval_nsec, enable_phase_detect, and MP.

Add new options to let the user set the timer interval and turn on
enable_phase_detect.

Make enable_phase_detect control whether we run initialize_timer().
