I have an old C code that includes some asm statements (I am a novice at this programming level).

      asm("movq %0, %%mm0"::"g"(*t));   // mm0 : target image (b)
      asm("movq %0, %%mm1"::"g"(*s));   // mm1 : src image (b)

When compiling with gcc 3.35 every think works fine.

Now, I try to compile the code with gcc 4.12 and the following error happens :

/tmp/cc13T7zq.s:38: Error: suffix or operands invalid for `movq'

Can you help me to fix this bug?

Thanks in advance,
