      Logger: introduce abstract interface for CodeEvent listeners. · 141ada02
      loislo@chromium.org authored
      New abstract class CodeEventListener was created.
      
      CodeEventLogger which is the base class for Jit, LowLevel
      and CodeAddressMap loggers was inherited from CodeEventListener.
      
      CodeAddressMap class was moved to serializer.cc because serializer is the only user for it. Actually it collects code names and pushes them to the standard log as SnapshotCodeNameEvent. So I extracted this code into separate function CodeNameEvent. It happens that this method works only when Serializer serializes an object. So I added direct log call there.
      
      CodeEventLogger class declaration was moved to the header
      because CodeAddressMap needs it.
      The code for the nested class CodeEventLogger::NameBuffer was left in the cc file.
      
      CpuProfiler now is inherit CodeEventListener but not used
      the loggers infrastructure yet due to the complex initialization schema. I'd like to fix that in a separate cl.
      
      BUG=none
      TEST=current test set.

      Skip samples where top function's stack frame is not setup properly · 69c2f54d
      yurys@chromium.org authored
      Stack iterator takes return address based on the frame pointer (ebp) and detects JS frames based on value at fp + StandardFrameConstants::kMarkerOffset. So in order the iterator to work correctly this values should be already setup for the current function. Stack frame is constructed at the very beginning of JS function code and destroyed before return. If sample is taken before before the frame construction is completed or after it was destroyed the stack iterator will wrongly think that FP points at the current functions frame base and will skip callers frame. To avoid this we mark code ranges where  stack frame doesn't exist and completely ignore such samples.
      
      This fixes cctest/test-cpu-profiler/CollectCpuProfile flakiness.
