Dan Gohman 9a38e3e399 Revert 71165. It did more than just revert 71158 and it introduced several regressions. The problem due to 71158 is now fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71176 91177308-0d34-0410-b5e6-96231b3b80d8		2009-05-07 19:46:24 +00:00

This directory contains test cases for the instcombine transformation.  The
dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
