Pranav Bhandarkar 4c3d3ecdf8 LLVM Bug Fix 13709: Remove needless lsr(Rp, #32) instruction access the ... subreg_hireg of register pair Rp. * lib/Target/Hexagon/HexagonPeephole.cpp(PeepholeDoubleRegsMap): New DenseMap similar to PeepholeMap that additionally records subreg info too. (runOnMachineFunction): Record information in PeepholeDoubleRegsMap and copy propagate the high sub-reg of Rp0 in Rp1 = lsr(Rp0, #32) to the instruction Rx = COPY Rp1:logreg_subreg. * test/CodeGen/Hexagon/remove_lsr.ll: New test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163214 91177308-0d34-0410-b5e6-96231b3b80d8		2012-09-05 16:01:40 +00:00
