[squirrelfish] SquirrelFish Extreme for non x-86 and embedded platforms

Hello, I would like to know whether WebKit JavaScript Engine SquirrelFish Extreme (SFX) has been reported to work on any embedded, non-x86 platform? I have built a recent WebKit nightly build on Windows and it works fine. However, there is use of Windows specific VirtualAlloc() API functions for allocating memory from virtual address space. What will be the alternative for this routine on non-Windows platforms, especially the embedded ones? Thanks. Regards, J R Shah
