This paper presents various improvements that were applied to OCamlJit2, a Just-In-Time compiler for the OCaml byte-code virtual machine. OCamlJit2 currently runs on various Unix-like systems with x86 or x86-64 processors. The improvements, including the new x86 port, are described in detail, and performance measures are given, including a direct comparison of OCamlJit2 to OCamlJit.
