The main reason was about backtracking token streams in the parser being

Good catch :)

Hi,
I am seeing some failures in the intl tests. I have done a fresh clone
and make dependencies.
One of the failing tests is intl/number-format/parse-percent.js. It
starts off like this:
var nf = new Intl.NumberFormat(['en'], {style: 'percent'});

What's the logic
Hi,
Very embarrassingly I just did a git svn dcommit instead of git cl
dcommit, and hit Ctrl-C halfway through. Thus bleeding_edge got two
out of three commits of a CL.
First of all, apologies for my mistake :/
Secondly, how do I revert to r14665?

r14668 contains the revert of r14667 and r14666 (verily, the number of
the beast). I'll re-land the CL shortly.
Sorry for the noise!

Hi Jakob,
I'm trying to get test-server.py running. It sounds like it could be
quite useful for debug-mode tests.
On my 192.168.0.0/24 network I have another host running a test server
(tools/test-server.py start, after doing the setup), and I copied
imported the remote server's .pem file into

How do I get my local machine to be aware of remote peers?
For the record, it turns out you have to tools/test-server.py approve
other-rsa.pem on both machines. Makes sense and works fine now.
Thanks!

Hi all,
I would like to implement support for ES6 generators in V8, and I wanted
to send an early mail to get some feedback.
Firstly, I would be happy if eventually generators could land upstream.
I don't know what the team's plans are in this regard -- is this a
feature you would want in V8?

Ah, this was the piece that I was missing. Thanks. I think that my
mental model had too many fairies in it, busily patching up

There were two independent bugs exposed through the additional

includes the original fix and should fix all these as well.
Thanks for following up on this,

I will add instrumentation to count -0 checks.
I added counters at sites that did SetFlag(kBailoutOnMinusZero). I then
ran each test in sunspider 100 times -- but via `load' instead of
looping, so perhaps it was not a good crankshaft

The numbers do fluctuate a bit; the only real constant here is that with
my patch we get minus zero bailouts being set for some unary math ops.
I'm going to see if I can whittle this down to one test in particular.
Got one

I didn't expect that, but it seems the additional allocation of Range
