asm inline

[Sergey Ivanov <icegood1980@xxxxxxxxx>]

Have code:
  #define MoveIntArrayToRight(IntCnt, LastSrcPos) \
    __asm__ __volatile__                          \
    (                                             \
     "std\n\t"                                    \
     "movl 4(%%esi), %%edi\n\t"                   \
     "rep\n\tmovsl\n\t"                           \
     "cld\n\t"                                    \
     :                                            \
     :"S" (LastSrcPos), "c" (IntCnt)              \
     : "%ecx", "%esi", "%edi" , "cc", "memory"    \
    )

why compiler says
"error: can’t find a register in class ‘CREG’ while reloading ‘asm’"
