[PATCH] D128911: Emit table lookup from TargetLowering::expandCTTZ()

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/TargetLowering.cpp:7974
+      DAG.getConstant(ShiftAmt, dl, VT));
+
+  SmallVector<uint8_t> Table(BitWidth, 0);
----------------
The RISC-V crash needs this to fix

```
Lookup = DAG.getSExtOrTrunc(Lookup, dl, getPointerTy(TD));
```


Still looking at AVR
