Use pthread_stackseg_np() to find the stack bounds on OpenBSD

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Landry Breuil]

And add an #ifndef __OpenBSD__ because we have pthread_np.h like FreeBSD but not pthread_attr_get_np()

Instead of checking the compiler-provided mangled symbol, you should add an entry for OS(OPENBSD) to wtf/Platform.h, and make it mutually exclusive with OS(NETBSD).

Hand-edited patch for the win! To whoever commits it, please add the 'Reviewed by' line to please the bots...

[Alexey Proskuryakov]

Can you upload a new patch with "Reviewed by Anders Carlsson" in ChangeLog, and mark the patch with cq? flag? In this case, all a committer needs to do is change that to cq+, which is more likely to happen soon than manually landing the patch.

We normally don't use this kind of indentation for preprocessor. Does this match something else in this file? If no, please change to plain "#if".

Ditto.

> Source/JavaScriptCore/heap/MachineStackMarker.cpp:422
> +# if OS(OPENBSD)

Ditto.

Ugh. Much easier to contribute to mozilla than to webkit..... such pain dealing with patch bureaucracy.

You don't need to ask for review when it's already reviewed.
