Bill Wendling 1fb43c32ed The method of doing the matching with a 'select' instruction was wrong. The ... original code was matching like this: if (match(A, m_Not(m_Value(B)))) B was already matched as a 'select' instruction. However, this isn't matching what we think it's matching. It would match B as a 'Value', so basically anything would match to it. In this case, a Constant matched. B was replaced with a constant representation. And then the wrong value would be used in the SelectInst::Create statement, causing a crash. After thinking on this for a moment, and after Nick L. told me how the pattern matching stuff was supposed to work, the solution was to match NOT an m_Value, but an m_Select. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58946 91177308-0d34-0410-b5e6-96231b3b80d8		2008-11-09 23:17:42 +00:00
