Practice Problem 3.50 (solution page 347)

For the following C code, the expressions vall-val4 all map to the program values i, f, d, and l:

double fcvt2(int *ip, float *fp, double *dp, long 1)

{

int i = +ip; float f = *fp; double = *dp;

*ip = (int) val1;

*fp = (float) val2;

*dp = (double) val3;

return (double) val4;

}

Determine the mapping, based on the following x86-64 code for the function:
