re PR tree-optimization/46909 (Logical OR expressions are miscompiled)
PR tree-optimization/46909
* gimple-fold.c (and_var_with_comparison_1): Save partial
result even in the is_and case, if both partial results
are the same, return it.
(or_var_with_comparison_1): Use is_or predicate instead of
innercode == TRUTH_OR_EXPR test. Save partial result
even in the is_or case, if both partial results are the
same, return it. In the !is_or case when both partial
results are the same, return the partial result instead
of boolean_true_node.
* gcc.c-torture/execute/pr46909-1.c: New test.
* gcc.c-torture/execute/pr46909-2.c: New test.
* gcc.dg/pr46909.c: New test.
