Actually, it seems our own Eli has written rather a good description
of these code models:
http://eli.thegreenplace.net/2012/01/03/understanding-the-x64-code-models/.

Well worth the read (the default models he talks about at the top are
essentially "static").

Cheers.

Yep. I tried it. It used a movabsq instruction instead and a static allocation. 
Thanks a lot. 

I will read it immediately. Again thanks.

Another finding is when I use both -code-model=large and -relocation-model=pic
(!!!!!note changed),
it still generate the static relocation. So does it mean  -relocation-model=pic
does not like to work
with  -code-model=large ? 

Thanks,
