[v8-users] Tips for SIMD optimization of code

2019-09-25 Thread Piyush Katariya

How aggressively V8 optimizes the JS code to translate into SIMD 
instructions (AVX, SSE, MMX etc) under the hood?

I am not interested in SIMD.js project. I am interested in the code 
patterns which V8 JIT see as legit for data parallelization using SIMD 
depending upon host CPU architecture.

Any detailed guide or blog will be helpful for me.


Thanks

Re: [v8-users] V8 build failing

2019-09-25 Thread Manikandan Kaliyaperumal

Hello,

Thanks for thorwing some light on this. So, we decided to move to the 
version you recommended, 7.7. But, it still fails with some "no rule" 
error. I just updated the VERSION=7.7 and ran it as is. Do i need to make 
any adjustments in the build.v8.sh or elsewhere? Please let me know.

[v8-users] Replacing constructor function

2019-09-25 Thread Darin Dimitrov

I am embedding V8 and I have the following javascript:

var TSObject = (function (_super) {
__extends(TSObject, _super);
function TSObject() {
return _super !== null && _super.apply(this, arguments) || this;
}
return TSObject;
}(String));

As an embedder, I have registered the custom "__extends" function on the 
global object and my C++ callback is successfully invoked. 

My purpose is to be able to intercept the instantiation of such objects:

var obj = new TSObject();

and to alter the type of js objects returned from the TSObject constructor 
(ideally by invoking some user provided C++ callback). Can such a hook be 
achieved from inside the "__extends" callback?

The closest I could get is provide custom constructors for the base class 
but when the "_super.apply(this, arguments)" call is made, I am losing the 
information about TSObject and I only have access to the base class.

Is there some way that I could walk the call frames and replace this 
constructor or reach the TSObject function so that I have information about 
this type? 

I can get the current callstack by using "v8::StackTrace::CurrentStackTrace" 
but this only gives me the function name as Local and I cannot 
reach the actual Local from this frame.

Re: [v8-users] NewDefaultPlatform() unresolved external symbol

2019-09-25 Thread Joe Smack

I followed the instructions. I've tried several different setups and it 
just seems to me that V8's debug setup is screwed up. (Release build is 
fine.)

Re: [v8-users] V8 build failing

2019-09-25 Thread Jakob Kummerow

Ah. These errors make sense, *.googlecode.com doesn't exist any more.
You'll have to figure out where to get those dependencies (at the
right versions!) nowadays. After putting them all in the right places, run
"gclient runhooks" instead of "gclient sync" (which usually implies the
former).

If all the archeology ends up taking too much time, your alternative is to
update to a non-ancient version of V8, where everything works out of the
box.

Re: [v8-users] V8 build failing

2019-09-25 Thread Jakob Kummerow

First off, version 3.28.71 is *very outdated*. It hasn't been touched in
five years. If it suddenly stopped working for you, then that's certainly
not due to a change in V8.

Also, 3.28.71 is not a good version to pick. If you must use a
five-year-old version, then you should at least pick branch-heads/3.28,
which has 19 backmerged (=important) fixes on top of the 3.28.71 base
version. Even better, update to something more recent. branch-heads/7.7
would be a good candidate right now.

One thing I noticed in your build script is that you should run "gclient
sync" *after* "git checkout $VERSION". Fixing that might just be enough to
solve this issue.

I don't remember how we got dependencies back in those days. I think we ran
"make dependencies", or maybe that was in even earlier years. I'm pretty
sure we didn't manually clone gyp.

That's your clue for where to dig deeper.

we are not much familiar with the C++ GN way of code building

3.28 is so old, it doesn't use GN.

[v8-users] V8 build failing

2019-09-25 Thread Manikandan Kaliyaperumal

Hello,

I have been struggling with this V8 build fail for a day or two now and any 
help on this would be much appreciated.

We use V8 version in our project.for a script process engine. It suddenly 
stopped working and build fails.

Herewith, i am sharing my build.v8.sh and Docker file for your reference and 
any pointers on this would be helpful as we are not much familiar with the C++ 
GN way of code building here.
