[Beignet] a question about default optimize option when building

[彭席汉]

Hi:

My CL kernel program looks like as follow:

__global unsigned char *p;
int a, b, c, d;

res1 = *p * (a*b + c*d);

<some code here>

res2 = *p * (a*b + c*d + 1);


If I use default build option, for res2, what will EU do? read global memory for pointer p again and do computing of "a*b + c*d" again?
