Comment:
Thanks for the patches and benchmark. I found the missing optimisation in
the backend and fixed that:
{{{

* Add missing constant folding and optimisation for unsigned division
Noticed by Denys Rtveliashvili <[email protected]>, see #4004
}}}
and added some inlinings:
{{{

* inline allocaArray0, to fix withCString benchmark
Mon Apr 19 14:53:33 BST 2010 Simon Marlow <[email protected]>
* INLINE alloca and malloc
}}}
With these changes I get similar results to you with the benchmark
program.
