Forgot to mention: I've added the -fno-reorder-blocks flag to PowerPC
tests because otherwise bbro pass copies call to g() which breaks
number of nops. Roughly
if (a > 10 && f ())
ret += rec (a - 1);
g ();
is converted to
if (a <= 10) {
lab:
g();
} else {
if (!f())
goto lab;
ret += rec (a - 1);
g ();
}
-Y
