gcc : ChangeLog tree-chrec.c
Log message:
PR tree-optimization/20216
* tree-chrec.c (tree_fold_factorial): Delete.
(tree_fold_binomial): Change argument list to take a return type
and change the type of K to unsigned int. Rewrite to avoid explicit
evaluation of factorials, and (recursively) calling fold to perform
compile-time arithmetic. Return NULL on (internal) overflow.
(chrec_evaluate): Change type of K to an unsigned int. Avoid
calling tree_fold_binomial unnecessarily. Return chrec_dont_know
if any intermediate calculation overflows.
(chrec_apply): Update call to chrec_evaluate.
