So you expect us to somehow generate
val2 = -len;
switch (len) {
case 7:
do_sd(val, mem, val2++);
case 6:
do_sd(val, mem, val2++);
ca

Note the cost for constant loading usually is expensive which is why this case
is usually ignored ...
It is more costly on in-order chips though, especially RISCV where constant
forming takes 3 instructions
