The tree_expr_nonnegative_p function, used for checking if a tree expression is non-negative, has been moved to a numbered alias (tree_expr_nonnegative_p@1). This change simplifies pattern matching and symbol resolution within the compiler’s internal representation, as indicated by PR tree-optimization/126087.
