You wrote ConstAddr but I actually read ConstPtr (i.e., ConstObj for ootype). Indeed, ConstAddr is not used at all by ootype, so there should be no problem (at least in this respect :-)). ciao, Anto ___ pypy-dev@codespeak.net http://codespeak.net/mailman/listinfo/pypy-dev

Could you explain why > ConstAdrr were bad please? Because the blackhole interpreter doesn't use ConstXxx at all. The constants are now encoded directly in the jitcode -- in three lists, a list of integers, a list of references, and a list of float. There is almost no ConstXxx prebuilt any more. It seemed like a waste to need a fourth list just for addresses when they would fit in the list of integer constants too, hence I did AddressAsInt. It's a rather natural thing to do for lltype, given that we could already convert between addresses and integers at runtime. I'm a bit confused, btw: I thought that ootype did not need ConstAddr at all, because it used ConstObj for all pointer-ish things. A bientot, Armin. ___ pypy-dev@codespeak.net http://codespeak.net/mailman/listinfo/pypy-dev
