So is this valid high-level Cmm code? What's the proper way to allocate
Stack (and/or Heap) memory from high-level Cmm code?

?

I've tried using `(ret1,ret2) = call stg_fun (arg1,arg2);` in a Cmm
file, but I get a parser error on `call` with GHC HEAD; only when leave
out the return value assignement, i.e. when I use only `call stg_fun
(arg1,arg2);`, it gets parsed succesfully. Is this a bug in the
CmmParser?
