[PATCH] D131729: [RISCV] Move xori creation for scalar setccs to lowering.

[Craig Topper via Phabricator via llvm-commits]

craig.topper updated this revision to Diff 452789.
craig.topper added a comment.

Add more comments to the setcc lowering code. Swap the operands when we swap
the condition code. Use isInt<12> for the range check after guarding against
signed integer overflow.
