   @mehrdadh Nice you found the solution :-) Basically with `-DARM_MATH_AUTOVECTORIZE` you're avoid the problematic code in 
   1) `arm_nn_mat_mult_nt_t_s8.c` and 2) `arm_softmax_s8.c`.
   
    For the issue 1) I think that's fine if gcc is really autovectorizing the C code now being built (instead of the inline asm that caused the "impossible constraint" error), but for 2) issue, it's an ICE -- internal compiler error , so I think it points to a serious but in the compiler and must be investigated.
   
   I'm curious if there is any reason for selecting this particular tag and cherry-picking this particular commit?
