linux: TCMalloc-based C++ heap profiler.
Requires compiling with linux_use_tcmalloc=1.
When enabled by --heap-profiler flag in test_shell exposes
chromium.HeapProfiler object to JavaScript. The object has three
methods:
o start() -- starts profiling
o dump() -- dumps data accumulated since start() to file
named like chromium-YYYY-MM-DD-TS.heap
o stop() -- stops profiling.
Output can be analyzed by third_party/tcmalloc/tcmalloc/src/pprof.
For example:
$ third_party/tcmalloc/tcmalloc/src/pprof \
sconsbuild/Release/test_shell \
chromium-2009-11-06-1234567890.heap
See http://code.google.com/p/google-perftools/ for details on how to
use pprof.
