[Jozef Lawrynowicz via Phabricator via llvm-commits]

jozefl added inline comments.


================
Comment at: llvm/lib/Target/MSP430/MSP430ISelLowering.cpp:1106-1107
+    //
+    // TODO: If op0 is not a register, it would be more efficient to use an Rxx
+    // shift.
+    if (OpSize == 16 && Op.getOpcode() == ISD::SRL)
----------------
There are some pre-existing missed optimizations when shifting memory operands, so I'm going to fix them along with this TODO in a separate commit.
