2008-11-10Third time's a charm.Bill Wendling
The previous patches didn't match correctly. Also, we need to make sure that the conditional is the same before doing the transformation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58978 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-09Correction for the last patch. Should match the conditional in the first partBill Wendling
of the select match, not the select instruction itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58947 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-09The method of doing the matching with a 'select' instruction was wrong. TheBill Wendling
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

2008-11-09If the LHS of the FCMP is coming from a UIToFP instruction, then we don't wantBill Wendling
to generate signed ICMP instructions to replace the FCMP. This would violate the following: define i1 @test1(i32 %val) { %1 = uitofp i32 %val to double %2 = fcmp ole double %1, 0.000000e+00 ret i1 %2 } would be transformed into: define i1 @test1(i32 %val) { %1 = icmp slt i33 %val, 1 ret i1 %1 } which is obviously wrong. This patch modifes InstCombiner::FoldFCmp_IntToFP_Cst to handle when the LHS comes from UIToFP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58929 91177308-0d34-0410-b5e6-96231b3b80d8
