re PR tree-optimization/79408 (Missed VRP optimization of integer modulo)
PR tree-optimization/79408
* tree-vrp.c (simplify_div_or_mod_using_ranges): If op1 is not
constant, but SSA_NAME with a known integer range, use the minimum
of that range instead of op1 to determine if modulo can be replaced
with its first operand.
* gcc.dg/tree-ssa/pr79408.c: New test.
