Do you have any opinion about adding a warning for:
int f(char c)
{
return 10 * (c == 13) ? 1 : 2;
}The multiplication has no effect. The function returns either 1 or 2. It would be interesting to know how a MELT script could look like for such a case. As far as I see the multiplication doesn't exist in the gimple format (looking at a.c.004t.gimple generated by -fdump-tree-all).
