839450 - Add Parsemark to the repo

Status: RESOLVED WONTFIX

(Core :: JavaScript Engine, defect)

Attachment: parsemark files

cdleary created a parsing speed benchmark called Parsemark.

js/src/tests/parsemark.py is the script he used to run it.  In my experience, the output of parsemark.py is extremely unreliable.  For whatever reason, the times it measures have way too much noise.  I think we should just delete it.

However, I have a copy of the benchmark that I modified so it could be used within the Sunspider harness.  Each test has two files.

- A foo.data file, which contains the source code to parse.

- A foo.js file, which contains a single line like |parse(snarf("foo.data"));|.

I had success using it a while back (https://blog.mozilla.org/nnethercote/2011/07/01/faster-javascript-parsing/).

I've attached a gzip'd tarball of the test files.  They can just be dropped into a Sunspider repo, under the tests/ directory, and then you can just use Sunspider's --suite option to run them.

It seems like this is something we should have in the repository.  Any suggestions on where to put it?  One difficulty is that it is 8 MB of source code...

This is going nowhere.
