* module/language/tree-il/peval.scm (singly-valued-expression?): New helper. (truncate-values): Use the helper. (make-operand): Minor refactor. (set-operand-residual-value!): Try to undo the effects of (values FOO), if the continuation will check itself for the correct number of values. (peval): Fold helpers into fold-constant. Add a constant-expression? case for (values FOO). Add a new context: "values", for contexts in which multiple values are allowed, either because of being in a tail context relative to a function, or because of let-values. "value" is now for single values. Don't visit operands for "values", as their binding form truncates to one value. Add a case to fold (values ...) forms. Fix folding of (lambda), to process the cases in values context instead of tail context (which could have been "value", which would cause the procedure to truncate). |
