History

Nick Lewycky bf433e5f46 Tweak this test. We can analyze what happens and show that we still do the right thing, instead of merely being unable to analyze and the transform doesn't occur. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127149 91177308-0d34-0410-b5e6-96231b3b80d8		2011-03-07 02:10:18 +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.
