* fix a bug noticed by inspection: when instcombine sinks loads throughChris Lattner2009-11-011-0/+21
| | | | | | | | | phis, it didn't preserve the alignment of the load. This is a missed optimization of the alignment is high and a miscompilation when the alignment is low. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85736 91177308-0d34-0410-b5e6-96231b3b80d8

* We currently only run ipsccp at LTO time, which is silly. It subsumesChris Lattner2009-11-011-0/+19
| | | | | | | | | | | | | | ipconstprop and doesn't take much time. Just run it in its place. This adds a testcase for it, which I plan to expand to cover other "integration" cases, where we expect the optimizer to be able to eliminate various things. Due to phase order issues we've regressed in a number of areas and integration tests are the only way I see to prevent this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85729 91177308-0d34-0410-b5e6-96231b3b80d8
