hey, as long as the ".set" macro-hack keeps working and the
assembly files are compatible between the two, it's all good

do consider giving alan and peter a heads-up. also if it means that
there's a solution to using "/" in "sv.xxx/yyy/zzz" because it's
explicitly avoided, that would be really good.  i just tried this
in a test.s and it actually worked

     addi 4/2,2,1

"powerpc64le-linux-gnu-as test.s" did not barf on that.
