Hi Allan,

Thanks for your response! It is good to know someone who's worked on 

Yes, the qtwebkit did not work/compile on ppc64le. It crashes (assertion 
failure) in isPageAligned() macro. The page alignment is not correct on 
ppc64le. In addition to this, the page allocation logic and the frame 
stack functionality is not working as expected on this platform. The tried 
to modify the page alignment logic and the execution went ahead, only to 
hang in dtoa()/mult() functions in WTF. I think the page block and JS 
stack functionality needs particular attention.

As you've already worked on ppc64be, your experience of porting the code 
would be precious to me. Could you please share your experience and advise 
on how I should proceed in this task of porting the code to ppc64le?

I haven't tried PPC64LE myself, when I last touched PPC64 it was to make 
endian 64bit work, so it might not configure correctly.
