Duncan Sands a921a46854 Simplify SplitVecRes_UnaryOp by removing all the code that is ... trying to legalize the operand types when only the result type is required to be legalized - the type legalization machinery will get round to the operands later if they need legalizing. There can be a point to legalizing operands in parallel with the result: when this saves compile time or results in better code. There was only one case in which this was true: when the operand is also split, so keep the logic for that bit. As a result of this change, additional operand legalization methods may need to be introduced to handle nodes where the result and operand types can differ, like SIGN_EXTEND, but the testsuite doesn't contain any tests where this is the case. In any case, it seems better to require such methods (and die with an assert if they doesn't exist) than to quietly produce wrong code if we forgot to special case the node in SplitVecRes_UnaryOp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@143026 91177308-0d34-0410-b5e6-96231b3b80d8		2011-10-26 14:11:18 +00:00
