This is not a bug. But the modified register is a register of the input list, so gcc should know that it will be used. Or did I misunderstood this [1]: "5.3 Clobber list [..] We shoudnt list the input and output registers in this list. Because, gcc knows that "asm" uses them (because they are specified explicitly as constraints)." cu FG [1] (http://www.ibiblio.org/gferg/ldp/GCC-Inline-Assembly-HOWTO.html#ss5.3 -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24282
