pub fn rewrite_recursive_calls_expr(
expr: &Spanned<Expr>,
targets: &HashSet<String>,
fuel_var: &str,
) -> Spanned<Expr>Expand description
AST transform: walk expr and replace every recursive call to a fn
in targets with fn__fuel(fuel_var, …args). Inter-fn mutual calls
in the same SCC are rewritten identically (the fuel parameter is
threaded through the whole group).
