First of all, we only support the FTL on Darwin - the Linux "support" is highly experimental and I don't know if the people working on it have done anything in a long time. This is true both of the code on the WebKit side, which was originally implemented on Darwin with Darwin-specific assumptions, and also of the LLVM side, which also was originally Darwin-specific. None of that code should be Darwin-only forever but the Linux bits have to be written by somebody.
That said, you could probably get the ball rolling on a proper port by opening a bug on bugs.webkit.org and posting the crash you are seeing. You definitely don't need a testing branch of LLVM. Either trunk works or nothing works. -Fil > On Apr 16, 2014, at 7:46 AM, Vahag Vardanyan <v...@ispras.ru> wrote: > > I have used the latest version from llvm.org and I am getting the error > desribed before.
