I just finished implementing a list-based solution to the n-queens problem and
that does run 5-14x faster in OCaml than on my HLVM:
n=8
OCaml: 0.012s
HLVM: 0.190s
n=9
OCaml: 0.088s
HLVM: 0.591s
n=10
OCaml: 0.740s
HLVM: 3.713s
n=11
OCaml: 6.68s
HLVM: Out of memory
HLVM ran out of memory in the last case because I have not yet reintegrated
the GC.
