================
Comment at: llvm/lib/Target/RISCV/RISCVInstrInfo.h:303
+  this concept does not exist in the specification, and requires source
+  knownledge to be preserved.

----------------
knownledge -> knowledge


================
Comment at: llvm/lib/Target/RISCV/RISCVInstrInfo.h:328
+  overlap constraint mentioned above.

----------------
How do we represent "undefined" for fma, integer multiple-accumulate where the destination is also an arithmetic source. Also vslideup where the destination is used for elements below offset and for the tail, but only tail follows the tail policy.

How do we represent tail "undefined" vs tail "agnostic" for _MASK?
