if at all possible, try to use the mainline for new development (it will usually make your life much easier, and it will also make it possible to contribute any bugfixes/improvements you may make during your project, whatever it is). That being said, if for whatever reason you cannot affect this decision, have a look at parloop branch (tree-outof-ssa.c:go_out_of_ssa and its users) -- the early version of loop parallelization had to solve the same problem, Zdenek
