--- Comment #5 from Martin Liška <marxin at gcc dot gnu.org> ---
The r237185 revision really caused that one slsr opportunity is gone, however
there's still one remaining (-fno-tree-slsr vs -ftree-slsr) show:
<bb 3>:
- a2_15 = s_11(D) * 4;
- _4 = (long unsigned int) a2_15;
- _5 = _4 * 4;
- _6 = -_5;
- x2_16 = c_13(D) + _6;
+ x2_16 = x1_14 + _3;
goto <bb 5>;
I'm going to send patch to ML.
