Reason for revert: The random nature of the tests caused the following buildbot to fail: https://build.chromium.org/p/client.v8/builders/V8%20Linux%20gcc%204.8/builds/4724/steps/Check/logs/stdio Original issue's description: > [profiler] Implement POC Sampling Heap Profiler > > This implements a proof-of-concept sampling based heap profiler inspired by > tcmalloc's heap profiler [1] and Go's mprof/memprofile [2]. > > The basic idea is the sample allocations using a randomized Poisson process. At > any point in time we can cheaply request the set of live sample objects that > should be a representative sample of heap. Samples include stack-traces from the > allocation sites, making this an effective tool for memory leak debugging. > > Unlike AllocationTracking, this is intended to be cheap and usable online in > production. > > The proof-of-concept is only sampling new-space allocations at this point. > Support for sampling paged space and native allocations is anticipated in the > future. > > [1] http://goog-perftools.sourceforge.net/doc/heap_profiler.html > [2] http://blog.golang.org/profiling-go-programs > > Committed: https://crrev.com/e5a9947811db9c9e23557dbad27f8b8a349b3262 > Cr-Commit-Position: refs/heads/master@{#33448} TBR=jochen@chromium.org,alph@chromium.org,hpayer@chromium.org,yangguo@chromium.org # Skipping CQ checks because original CL landed less than 1 days ago.
