1770544 - multiple definitions of AUTO_PROFILER_THREAD_WAKE on non-MOZ_GECKO_PROFILER platforms

Status: RESOLVED FIXED

(Core :: Gecko Profiler, defect, P3)

Description

[Landry Breuil (:gaston)]

this one is filling my build logs since the profiler headers are included from everywhere:

 7:23.02 /usr/obj/m-c/dist/include/mozilla/ProfilerThreadState.h:90:9: warning: 'AUTO_PROFILER_THREAD_WAKE' macro redefined [-Wmacro-redefined]
 7:23.02 #define AUTO_PROFILER_THREAD_WAKE mozilla::AutoProfilerThreadWake PROFILER_RAII
 7:23.02         ^
 7:23.02 /usr/obj/m-c/dist/include/mozilla/ProfilerThreadSleep.h:21:11: note: previous definition is here
 7:23.03 #  define AUTO_PROFILER_THREAD_WAKE

maybe an #ifndef could be added to the fallback definition in ProfilerThreadSleep.h ?

Thank you for the report.
Hmm, the one in ProfilerThreadSleep.h is an empty fallback for non-MOZ_GECKO_PROFILER builds, but the one in ProfilerThradState.h is always defined.

I rather think that the "real" definition in ProfilerThreadState.h should be guarded with in #ifdef MOZ_GECKO_PROFILER, similar to how AUTO_PROFILER_THREAD_SLEEP is.

I may not have the time for it this week (traveling). Keeping the NI as a reminder.

you mean adding #ifdef MOZ_GECKO_PROFILER around https://searchfox.org/mozilla-central/source/tools/profiler/public/ProfilerThreadState.h#90 ? or also include AutoProfilerThreadWake class definition within it ? the class is also defined here: https://searchfox.org/mozilla-central/source/mozglue/baseprofiler/public/BaseProfiler.h#467

No hurry, can test patch when you have one to confirm the warnings are gone on platforms without profiler :)
