--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- So the difference between func3 and func4 is the following: func3 does: ``` D.2811 = 1; _4 = num; _7 = D.2811; if (_4 < _7) ``` While func4 does: ``` D.2821 = 1; _4 = D.2821; _7 = num; if (_4 < _7) ``` func3 will reduce to `num < 1` which itself is just `num != 0` and then we get `num != 0 ? 1 : num` and that reduces `num != 0 ? 1 : 0` which then reduces to just `num != 0` While for func4 we get: `num > 1` and `num > 1 ? num : 1` which reduces down to just `min<num, 1>` and GCC does not reduce that further to `num != 0` and that is what PR 104296 is about.
