    M llvm/test/Transforms/FunctionAttrs/noundef.ll

  Log Message:
  -----------
  [FunctionAttrs] Don't infer noundef when return has nofpclass (#191822)

- Fixes: #191338

nofpclass violations on a return produce poison.
Poison returns marked noundef are UB.
This turns off noundef inference when nofpclass attributes are present.
