From a combination of @llvm.assume calls (and perhaps through other means, such as range metadata), it is possible that all bits of a return value might be known. Previously, InstCombine did not check for this (which is understandable given assumptions of constant propagation), but means that we'd miss simple cases where assumptions are involved. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@217346 91177308-0d34-0410-b5e6-96231b3b80d8
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.
