[Diana Picus via Phabricator via llvm-commits]

rovka added inline comments.


================
Comment at: llvm/trunk/include/llvm/CodeGen/GlobalISel/LegalizerCombiner.h:98
       unsigned SizeDiff = DstTy.getSizeInBits() - SExtSrcTy.getSizeInBits();
       auto SizeDiffMIB = Builder.buildConstant(DstTy, SizeDiff);
       unsigned TruncSrcReg = DefMI->getOperand(1).getReg();
----------------
You forgot this G_CONSTANT :)
