Old Synopsis: Internal compiler error in simplify_subreg, at simplify-rtx.c:2452
New Synopsis: [3.2 regression] ICE in simplify_subreg, at simplify-rtx.c:2452

State-Changed-Why:
Confirmed.
The problem boils down to the following line:
unsigned int foo (unsigned int u) { return (u >> 32) & 0xffff; }
Compiling this with "gcc -O -c" on i686-pc-linux-gnu crashes gcc 3.1 - 3.2.1.
gcc 2.95.x, 3.0.x and mainline are not affected.
