We have seen some interest in MIPS on the mailinglist and little in the bugtracker but no contribution from these folks. So the other week I decided to attempt to run some of our regression tests on a MIPS platform. The only problem is that I don’t have any MIPS hardware… can you change that?

I had this idea of implementing enough of MacroAssembler to run/compile yarr with the RegexJIT.cpp. In the absence of MIPS hardware I used qemu-mipsel useremulation, enabled yarr/RegexInterpreter.cpp and ran into an infinite loop. I have fixed the bug and landed the patch upstream and now I’m able to complete run-javascriptcore-tests using yarr. The next step will be to work on the MacroAssembler and learn about MIPS assembly…. maybe I progress a bit more next weekend.
