Expose aliasing information in getModRefInfo (or viceversa?)
I'm trying to understand what is the result we'd seek in the example
in D38569 (pasting here for quick access)
double f(double a)
{
double b;
double c,d;
double (*fp) (double) __attribute__ ((const));
/* Partially redundant call */
if (a < 2.0)
{
fp = sin;
c = fp (a);
}
else
{
c = 1.0;
fp = cos;
}
d = fp (a);
