[llvm-commits] CVS: reopt/lib/LightWtProfiling/Globals.h

[Brian Gaeke]

Changes in directory reopt/lib/LightWtProfiling:

Globals.h updated: 1.7 -> 1.8

---
Log message:

Provide decl of llvm_first_trigger, because everyone wants its address.

Provide declarations of timer_interval globals and a ModuleProvider for
the currently reoptimized Module.

Provide extern decl of bool enable_phase_detect, so that we can start
reducing the commented-out code there.
