When compiling the following program with -O2, gcc gives an ICE "internal
compiler error: in trunc_int_for_mode, at explow.c:56".
Versions affected:
gcc (GCC) 4.4.3 20100127 (Red Hat 4.4.3-4)
gcc (GCC) 4.5.1 20100521 (prerelease)
================================================
static inline unsigned parity(unsigned x)
{
return (unsigned) __builtin_parity(x);
}
unsigned f(unsigned rpoly)
{
return parity(rpoly & 1) ^ parity(rpoly & 6);
}
================================================
