Chris Lattner 6007b84a5b Generalize (zext (truncate x)) and (sext (truncate x)) folding to work when ... the src/dst are not the same size. This catches things like "truncate 32-bit X to 8 bits, then zext to 16", which happens a bit on X86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30557 91177308-0d34-0410-b5e6-96231b3b80d8		2006-09-21 06:00:20 +00:00
