incorrect order of evaluation of side effects for some builtins
Impact The order of evaluation of the arguments of the builtin functions uint256addmod, uint256mulmod, ecadd and ecmul does not follow source order. • For uint256addmoda,b,c and uint256mulmoda,b,c, the order is c,a,b. • For ecadda,b and ecmula,b, the order is b,a. Note that this behaviour is...
