------- Comment #11 from pinskia at gcc dot gnu dot org 2007-06-26 21:33 ------- I can find a testcase, if we change where we generate the promotion at the RTL expansion time, worse code. Simple testcase:
int f(int b, char a)
{
if (b)
a = 1;
g(a);
}
You can see the difference by looking 3.4 vs 4.2's code generation :).
