Ahh. You are correct.
Re-converting now, since you've presumably committed patches to the

Hi List,
I'm running GHC and GCC head-to-head on the task of adding a bunch of
long IOUArray-Vectors really fast. My machine is a Linux-ppc PowerBook
and gets a runtime for the GHC-compiled binary that's about 10x as long
as for GCC. Simon M. tells me this should be much better. Here are the

In the latter case, I'd also like to know whether you also
have programs that will be broken by the change.
I don't use GADTs yet and I assume this change will not (seriously)
break our code, but let me/us

BZ the only cause that this code is only 3 times slower is that C version
BZ is really limited by memory speed. when tested on 1000-element
BZ arrays, it is 20 times slower. i'm not yet tried SSE optimization for
BZ gcc ;)
