Summary: too many slocs in DSEG

Initial Comment:
sdcc 2.9.0

too many slocs in DSEG, even  

/////////////////////////////////
example code:
void taskAIBufferExecute(void)
{
    static data char ch = 0;
    data float tx, ty;

    tx = (float)ADCRead(ch);

    ty  =        tx *  3.123898E-5
         + x[ch][0] *  1.2495591E-4
         + x[ch][1] *  1.8743388E-4
         + x[ch][2] *  1.2495591E-4
         + x[ch][3] *  3.123898E-5
         + y[ch][0] *  3.5897338
         - y[ch][1] *  4.851276
         + y[ch][2] *  2.9240527
         - y[ch][3] *  0.6630105;
