| * | Use opt -S instead of piping bitcode output through llvm-dis. | Dan Gohman | 2009-09-08 | 1 | -1/+1 |

| * | Change these tests to feed the assembly files to opt directly, instead | Dan Gohman | 2009-09-08 | 1 | -1/+1 |
| | | | | | | | | of using llvm-as, now that opt supports this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81226 91177308-0d34-0410-b5e6-96231b3b80d8 | ||||
| * | Improve instcombine's handling of integer min and max in two ways: | Dan Gohman | 2008-09-16 | 1 | -0/+22 |
| - Recognize expressions like "x > -1 ? x : 0" as min/max and turn them into expressions like "x < 0 ? 0 : x", which is easily recognizable as a min/max operation. - Refrain from folding expression like "y/2 < 1" to "y < 2" when the comparison is being used as part of a min or max idiom, like "y/2 < 1 ? 1 : y/2". In that case, the division has another use, so folding doesn't eliminate it, and obfuscates the min/max, making it harder to recognize as a min/max operation. These benefit ScalarEvolution, CodeGen, and anything else that wants to recognize integer min and max. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56246 91177308-0d34-0410-b5e6-96231b3b80d8 | |||||
