This patch reduces the differences between builds where the profiler is enabled and those where the profiler is disabled. It does this by removing numerous MOZ_GECKO_PROFILER checks. These changes have the following consequences. - Various functions and classes are now defined in all builds, and so can be used unconditionally: profiler_add_marker(), profiler_set_js_context(), profiler_clear_js_context(), profiler_get_pseudo_stack(), AutoProfilerLabel. (They are effectively no-ops in non-profiler builds, of course.) - The no-op versions of PROFILER_* are now gone. The remaining versions are almost no-ops when the profiler isn't built. --HG-- extra : rebase_source : 8fb5e8757600210c2f77865694d25162f0b7698a

// The Gecko Profiler defines AutoProfilerLabel, an RAII class for
|
|
// pushing/popping entries to/from the PseudoStack.
|
|
//
|
|
// 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 sPseudoStack.
|
|
//
|
|
// 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::ProfileEntry::Kind::CPP_NORMAL as the kind, and
|
|
// js::ProfileEntry::Category::OTHER as the category, because that's what the
|
|
// callbacks provided by the profiler use. (Specifying the kind or category in
|
|
// this file would require #including ProfilingStack.h in mozglue, which we
|
|
// don't want to do.)
