Even we have long silence on the list, someone may continue some effort to improve kaffe... For this summer, my SOC (summer of code) was to tackle arm jit3 code. # Oh, this topic is same as the last summer :-) Of course, the released version has a workable jit3 code for this arch, if you think even no 'global registers' are defined ;-<
But while trying to determine why it does not work, I installed qemu for mips and noticed mips-jit3 also does not work. So actually, I spent long time to find out why mips code does not work properly. Still, I can not print 'Hello World' by using the first regression test, but 'verbosejit' flag (which can be the easiest way to see how many methods are jit-compiled and executed) tells me so many methods becomes to be able to be compiled. I put diff's against official 1.1.8 release (rather than the latest 1.1.9) on 'http://www.kaffe.org/~inaba/kaffe-1.1.8-0915.patch' and if you are interested, please see what I did. There are three fixes I did 1) Trampoline code are modified incorrectly. A guy forgot mips needs delayed slot when you call subrouting. I reverted to older version. 2) Conversion routine are modified inproperly. If you need cvtif or something, you have to think proper return value register. I reverted to older version. 3) When you have exceptions, 'callee saved' registers shall be restored from callee method's stack. But original code handles it differently. And I have no smarter and generic way to handle this situation for the time being, the patched version restored the contents by VERY VERY ugly way. I hesitate to put this 'fix' back to the repository and this is the main reason I just let you know on the ML. Since, 'HelloWorldApp.main' method are jit-compiled by this mod, I hope we may have only one more bug before we can display the 'Hello World' on mips with jit3 technology.
