// The Gecko Profiler defines AutoProfilerLabel, an RAII class for
|
|
// pushing/popping frames to/from the ProfilingStack.
|
|
//
|
|
// This file defines a class of the same name that does much the same thing,
|
|
// but which can be used in (and only in) mozglue. A different class is
|
|
// necessary because mozglue cannot directly access sProfilingStack.
|
|
//
|
|
// Note that this class is slightly slower than the other AutoProfilerLabel,
|
|
// and it lacks the macro wrappers. It also is effectively hardwired to use
|
|
// js::ProfilingStackFrame::Category::OTHER as the category, because that's what
|
|
// the callbacks provided by the profiler use. (Specifying the category in
|
|
// this file would require #including ProfilingStack.h in mozglue, which we
|
|
// don't want to do.)
