Not sure. bdver2.
Reduced C code:
typedef float DBL;
struct {
DBL c_x, c_y
} Random_Simis_Cur;
Random_Simis_i;
DBL Gauss_Rand() {
int __trans_tmp_1;
DBL S, y = exp(S) / 0;
if (__trans_tmp_1)
return y;
return -y;
}
draw_ifs() {
while (Random_Simis_i--) {
Random_Simis_Cur.c_x = Gauss_Rand();
Random_Simis_Cur.c_y = Gauss_Rand();
}
}
Command line is
$ /home/dcb/gcc/results/bin/gcc -c -w -O3 -march=bdver2 -ffast-math bug717.c
