--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
"1" (0x00000000ffffffff)

says pass unsigned int (32bit register) here to the inline-asm. The other upper
bits of the register is not defined; only lower 32bit is defined. 

Since 0x00000000ffffffff fits in `unsigned int`. If you want a 64bit, an
unsigned long (or unsigned long long) use either a cast or use ull suffix to be
more excplit.
