The following (IMHO valid) testcase triggers an ICE since GCC 4.3.0
(when fixed-point types were introduced):
============================================================
void foo()
{
asm("" : : "r"(0r));
}
============================================================
bug.c: In function 'foo':
bug.c:4: internal compiler error: in init_move_cost, at reginfo.c:270
Please submit a full bug report, [etc.]
Technically, this is a regression since the code did not crash the
compiler before (because it was rejected earlier).
