This is a reland of ed7e4554db:
- fixing platform names for tickprocessor
- UnixCppEntriesProvider => LinuxCppEntriesProvider
- MacCppEntriesProvider => MacOSCppEntriesProvider
Original change's description:
> [mjsunit][tools][d8] Full roundtrip tickprocessor test
>
> - Add os.d8Path property
> - Add os.name property
> - Change tickprocssor test to use command line arguments for testing
> various configurations
> - Change tickprocessor test to create a temporary v8.log and read it
> back in on linux only
> - Rearrange code in tickprocessor.mjs to allow instantiating the
> CppEntriesProvider directly
> - Drop complete symbol-list for tickprocessor-test-large.log for better
> code searching in V8
>

Chrome V8 profiling log processor
|
|
</h3>
|
|
<p>
|
|
Process V8's profiling information log (sampling profiler tick information)
|
|
in your browser. Particularly useful if you don't have the V8 shell (d8)
|
|
at hand on your system. You still have to run Chrome with the appropriate
|
|
<a href="https://code.google.com/p/v8/wiki/ProfilingChromiumWithV8">
|
|
command line flags</a>
|
|
to produce the profiling log.
|
|
</p>
|
|
<h4>Usage:</h4>
|
|
<p>
|
|
Click on the button and browse to the profiling log file (usually, v8.log).
|
|
Process will start automatically and the output will be visible in the below
|
|
text area.
|
|
</p>
|
|
<h4>Limitations and disclaimer:</h4>
|
|
<p>
|
|
This page offers a subset of the functionalities of the command-line tick
|
|
processor utility in the V8 repository. In particular, this page cannot
|
|
access the command-line utility that provides library symbol information,
|
|
hence the [C++] section of the output stays empty. Also consider that this
|
|
web-based tool is provided only for convenience and quick reference, you
|
|
should refer to the
|
|
<a href="https://code.google.com/p/v8/wiki/V8Profiler">
|
|
command-line</a>
|
|
version for full output.
