| 2011-07-01 | Improve constant folding of undef for binary operators. | Dan Gohman |
| 2011-05-07 | The comparision "max(x,y)==x" is equivalent to "x>=y". Since the max is | Duncan Sands |
| 2011-05-04 | Add variations on: max(x,y) >= min(x,z) folds to true. This isn't that common, | Duncan Sands |

| 2011-02-01 | Have m_One also match constant vectors for which every element is 1. | Duncan Sands |
| 2011-01-30 | Commit 124487 broke 254.gap. See if disabling the part that might be triggered | Duncan Sands |

| 2011-01-29 | Move InstCombine's knowledge of fdiv to SimplifyInstruction(). | Frits van Bommel |
| 2011-01-29 | Fix typo: should have been testing that X was odd, not V. | Duncan Sands |
| 2011-01-28 | My auto-simplifier noticed that ((X/Y)*Y)/Y occurs several times in SPEC | Duncan Sands |
| 2011-01-25 | In which I discover that zero+zero is zero, d'oh! | Duncan Sands |
| 2011-01-25 | Turn off this test - the corresponding instsimplify logic has been | Duncan Sands |
| 2011-01-25 | According to my auto-simplifier the most common missed simplifications in | Duncan Sands |
| 2011-01-20 | At -O123 the early-cse pass is run before instcombine has run. According to my | Duncan Sands |
| 2011-01-18 | For completeness, generalize the (X + Y) - Y -> X transform and add X - (X + ... | Duncan Sands |
