This leaves the ICE problem in attachment 15700. Is my assembly constraint
bogus (in which case I'd prefer a nice diagnostic, as was the case in gcc
4.2.4, to an ICE) ? I tried three choices for the inline asm:

__asm__("psrlq %1,%0" : "+x,x"(x) : "x,m"(sh));  --> ICE
__asm__("psrlq %2,%0" : "=x,x"(x) : "0,0"(x), "x,m"(sh));  --> ICE
__asm__("psrlq %2,%0" : "+x,x"(x) : "0,0"(x), "x,m"(sh));  --> ok

But having + _and_ a back reference is superfluous, isn't it ?

E.
