--- Comment #5 from anlauf at gcc dot gnu.org ---
Interestingly, we simplify IBITS(-1,0,32) to -1, and also the code generated
for ibits(x, p, lbits) produces the result expected by the reporter,
and which is also generated by Intel and NAG.
For ISHFT we have
/* ISHFT (I, SHIFT) = (abs (shift) >= BIT_SIZE (i))
? 0
: ((shift >= 0) ? i << shift : i >> -shift)
where all shifts are logical shifts. */
so we might as well consider doing what the reporter suggests.
