LLVM/clang support

[JMLX42]

Hello,

we're working on the C++ port of Minko (http://minko.io) to bring a bit more awesomeness to the Flash platform. Crossbridge is our dream come true!

But we're using C++ 2011 and I guess support for LLVM/clang 3.2+ is required to build properly. I'm creating this issue to have some feedback about the availability of such feature which as far as I understand is currently under development in the "future" branch.

Please also indicate how we can help: we have some C++ 2011 code base and we would be pleased to dedicate some C++ developers to make your work easier on this.

Thanks for the awesome work! :)

+1 for myself :) C++11 is close to complete. Exception handling is not working properly. The rest seems good. Besides this, there are several parts yet to be done to make SDK as a whole exactly as before. But all in all the availability depends on your required features.

+1 for LLVM clang 3.3 ;) this compiler is bad ass!

[cbakgly]

Hi @promethe42, forgot to say we are surely happy to see new dedicated contributors. Any concern please let us know.

[cbakgly]

+10 for 3.3 :). But I prefer to see a stable version coming out first. You guys are key to make it happen (at least faster).

[yi]

+1 PLEASE MAKE THIS HAPPEN

[rtissera]

+1 for 3.2 first, then move to 3.3 should be easier :)

[JMLX42]

3.2 has all the C++11 features we need I think.

Hello @promethe42 Please let me know what I can support for you and when your people decide to dedicate to this project! Also please feel free to email me. Thanks in advance!

[JMLX42]

Hi,

as soon as you have support for clang 3.2 we will give it a try to compile Minko and provide feedback.

We would like to help but to be honnest we don't know where to start :) Some input would be nice.

[cbakgly]

Oh, I guess I might put a SDK for your trying. (https://sourceforge.net/projects/crossbridge/files/Crossbridge_1.1.0.devbuild.alpha.dmg) As for a start, what I had were these: 1 setup env. 2 try examples to see basic usage. 3 get an overall idea on the process of compiler. 4 get an big picture on how crossbridge compiler works, especially for generating AS/ABC. 5 walk thru llvm/clang for specific code path and verifying via debugging.

I will post a blog here on the issue list for quick getting start. And any question/feedback please feel free to post. Thanks!

[rtissera]

I am interested in too :)

[JMLX42]

Can't you push everything on github in the "future" branch (or a new one)?

Thanks!

[cbakgly]

Ok, let me know what will be convenient for you

[JMLX42]

An "alpha" of Crossbridge with llvm/clang 3.2 support in the github repo + little doc about using it if any changes from the original build system. As soon as we got this we can give you feedback and see where things are going...

When do you think it could be up?

This week.

[bartoszalksnin]

before we get blog post there's doc from april about llvm 3.2 integration status i'm not sure how relevant it is to current progress https://github.com/adobe/crossbridge/blob/futures/LLVM_UPGRADE.md

[cbakgly]

It was a rough plan before going open source. The steps are roughly the same. Now the progress is measured against the samples.

Hi guys! Any update on this? :)

[JMLX42]

up

[JMLX42]

Any update would be greatly appreciated?

[fsilvestrim]

any updates on this one guys?

[vladkolotvin]

Any update on this?

[rtissera]

Would love to hear some news too :)

[ivanov-playkot]

I'm VERY interested in the update too (we need C++11 support, faster compilation/link of course, and pthread support <seems that alpha version doesn't support pthread, am I right?>)

Waiting update for this. Please show us some love :)

[cbakgly]

Love is never a single affair alone. It definitely needs many people's effort and time to make a big product come true.

[gonchar]

we can help you, what do you need? examples?

[rtissera]

I'm clearly astonished by such an attitude :(

@rtissera what did astonish you? I want to help with it, because, a few comments ago @cbakgly wrote "Now the progress is measured against the samples."

@cbakgly we can help, just help us helping you! We would love to contribute but we don't know where to get started...

[rtissera]

+1, would definitely help to help if we were given proper information and status

Hey Bros,

All you have is what I had when I took and is sitting on github. I believe you all surely can take it as well.

Read readme.md for status.

Let's say for example how to beat exception monster to get level up, ask yourself: 1 Do I understand the mechanism of c++ exception and where it affects in system libs? No? read the spec, read the code of system libs (at least libc, libc++, pthread) . Don't need it? ok, compile with -fno-exception.

2 Do I understand how clang handles? No? read the code, debug and see how it works on other archs (e.g. i386/arm) Compare the output against flascc 1.0's.

3 I know both well now. Sincerely congrats!!! Implement it, test it and contribute the patch!

4 I have questions. Make a little demo to narrow down the problem and verify contrary situation. Post to the issue list or other forum. See if anyone can answer. Google is the decent teacher.

You probably have to give great effort and time to make one step forward, since you are dealing with the very low level part of applications. Good luck.
