From my notes, it seems that I found that the return address from SysDepCallMethod() call was stored in A2 or A3, but was corrupted by the Exception handling "stack-unwind" function, which "restored" registers. The "restore" over-wrote the return address and caused a later crash, so I deleted it and exceptions then worked properly. At the time that I finished playing with jit1 of 1.0.7, I had only 13 failures in the test suite (running under Amiga OS). Several of those "failures" were due to OS dependencies like filename length limitations. I was unable to get jit3 to run in the short time that I spent on it. I then went on to 1.1.0 for a short time before abandoning the 68k platform. I'm currently starting to get together the development system for AmigaOS on PPC, with a view to getting stuck into the jit for PPC. As I have said before, that was May last year, a lot has changed since then, and I feel no paternal duty to stand up and fight for the mods I wrote back then, for what is now an obsolete version. If Kiyo's recent changes make the current system work better, then I'm in favour of them. I hope to be able to participate in this forum again soon, but using the Amiga OS4 PPC platform. cheers tony _______________________________________________ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
