      [counters] Annotate v8 with more runtime call counters. · 407d9fce
      cbruni authored
      By fully annotating the API with runtime counters we can properly measure
      how much time we spend in total in v8. When --runtime-call-stats is specified
      we now disable the fast-paths for callbacks to properly measure them.
      As a drive-by-fix this CL unifies the LOG messages in api.cc.
      Additionally we added missing timers to gain better resolution in the parser
      and callbacks.

      [counters] Making runtime counters reentrant. · 5e468666
      cbruni authored
      So far counters did not work when they were reentrant and thus would lead to
      wrong bookkeeping of the counter stack. Using a separate stack-allocated linked
      list to track the timer stack solves this issue. This is a temporary workaround
      with the limitations of the counter system in mind. Eventually we will move to
      the trace-based system for these kind of statistics.

      Fix call stack sampling for the case when native callback invokes JS function · 97f8f91b
      yurys@chromium.org authored
      The SafeStackFrameIterator used by CPU profiler checked if Isolate::c_entry_fp is null and if it is not it would think that the control flow currently is in some native code. This assumption is wrong because the native code could have called a JS function but JSEntryStub would not reset c_entry_fp to NULL in that case. This CL adds a check in SafeStackFrameIterator::IsValidTop for the case when there is a JAVA_SCRIPT frame on top of EXIT frame.
      
      Also this CL changes ExternalCallbackScope behavior to provide access to the whole stack of the scope objects instead of only top one. This allowed to provide exact callback names for those EXIT frames where external callbacks are called. Without this change it was possible only for the top most native call.
