Do not store fp and sp values in TickSample · 9ef762b6

yurys@chromium.org authored Jul 03, 2013

Their values are not used neither by the tick processor nor by CpuProfiler so it is just a waste of space.

TickSample used to be a transport for grabbed register values to TickSample::Trace, now they are passed in a special structure RegisterState which is allocated on the stack for the sampling period.

Some common pieces were moved from platform-dependent code into Sampler::SampleStack and TickSample::Init.

Fix test-cpu-profiler/FunctionCallSample flakiness under GC stress testing · 44dfaa2a

yurys@chromium.org authored Jul 03, 2013

The test flakes on "V8 GC Stress" bots and the sample looks like this:
[Top down]:
   90     0   (root) [-1] #0 1
    1     1    (program) [-1] #0 2
   89    89    (garbage collector) [-1] #0 3
which means that almost all samples are inside GC and we have no |start| node in the collected profile.

Running the test with different combinations of --gc-interval=500 and --stress-compaction flags gives the results quoted below. They don't give a ground to require |start| node presense in the profile when doing GC stress testing. So this change makes the |start| node optional in the collected profile if GC stress testing is on.

Correctly report stack trace when current function is FunctionApply builtin · 559e1d45

yurys@chromium.org authored Jul 03, 2013

When pc is inside FunctionApply builtin function the top frame may be either
2) Internal stack frame created by FunctionApply itself.
In this case we know its caller's pc and can correctly resolve calling function.
1) Frame of the calling JavaScript function that invoked .apply(). In this case we have no practical reliable way to find out the caller's pc so we mark the caller's frame as 'unresolved'.

All this logic is implemented in ProfileGenerator. SafeStackFrameIterator is extended to provide type of the current top stack frame (iteration actually starts from the caller's frame as we know top function from pc).

Reintroduce runtime zone to Isolate. · e3f34a58

bmeurer@chromium.org authored Jul 03, 2013

In case tcmalloc is not being used, the malloc()/free() overhead
can be significant for several runtime functions like StringReplace.
Therefore we reintroduce the runtime_zone into Isolate and reenable
the segment caching functionality of Zone.

There's now also a simpler version of ZoneScope w/o nesting capabilities.
