sf_erf.c: In function `erfcf':
sf_erf.c:16: Internal compiler error in calc_dfs_tree, at dominance.c:355
The following almost trival peice of code triggers an abort
in calc_dfs_tree because di->nodes == 7 and n_basic_blocks == 8
---------------------------sf_erf.c---------------------------------
extern float erfcf (float);
extern const float one,two;
float
erfcf(float x)
{
int hx,ix;
hx = one;
ix = hx & 0x7fffffff;
if(ix >= 0x7f800000)
return (float)(((unsigned)hx>>31)<<1)+one/x;
else
return two;
}
