I tried these when compiling my transputer emulator, (a simple instruction
interpreting one). I played around with the optimisation options quite
a bit but never got acc to perform significantly better than gcc.
[acc reports "SC1.0 1Mar1991" and gcc was probably 2.4.5 then]
Neither seemed to do at all well at inlining my big switch statement
procedure into my main loop - turning on inlining gained a couple of
percent, even with adding several "inline" keywords. Hand inlining two
procedures gained me 10% over that.
Hopefully both compilers have improved.
