I did contact Danno directly - I'll also post some additional details on the intent in this thread for others to be aware of.
I work at IBM, and currently my full time job is getting the PowerPC (PPC) version of V8 up to production quality. One of the major milestones of this work would be to have the code accepted back as a set of patches into the mainline V8 code base. The plan is also to continue to maintain this code - V8 is a language runtime that IBM would like to have running on it's platforms. There isn't yet a working implementation of crankshaft, nor the assembly based regex. Those will be completed but I've been working on basic functionality first. To work around these two issues by using the interpreted regex, and inverting the logic to enable crankshaft (so --nocrankshaft is the default) The port started as a copy of the ARM code base into a PPC directory. Then to allow for incremental progress, I started adding PPC support while still maintaining enough code to keep the ARM code compiling. I think this was the best approach to doing a port as it let me continue to have a working system to test against as I introduced more function. I could talk at length about the process of porting V8 to another platform but we're starting to run out of architectures to target :) Astute readers of the code will notice that there is still some ARM code in the src/ppc/* directory. There is an internal Jenkins based build system running the V8 tests against the code. It's at 85% pass rate at the moment. There are plans to get a public build system put up - but that may take a couple of weeks to get sorted out. Again - the code is out there for people to poke at: https://github.com/andrewlow/v8ppc - there are some additional IBM folk joining the GitHub project as committers. I welcome all participation from anyone willing to follow the V8 Committer guidelines.
