To be fair, anything that does not support BWX is really painful to deal with.
Take, for example, an 8-bit/byte store. Without BWX the sequence would be something like:
bic a0, #3, t1
and a0, #3, t4
ldl t2, (t1)
insbl a1, t4, t3
mskbl t2, t4, t2
bis t2, t3, t2
stl t2, (t1)
ret zero, (ra)
But with BWX, it becomes:
stb a1, 0(a0)
ret zero, (ra)
