Hi, Robert Schuster schrieb: > I now found a cacheflush implementation in libffi. I adjust this for > kaffe and report back. I took what was said here[0] as a base for an OABI- & EABI-compliant implementation of the cache flushing.
It compiles nicely (I can only test the EABI-variant here). Unfortunately it does not work at runtime. That means I get the same assertion failure as before: kaffe-bin: exception.c:100: vmExcept_setJNIFrame: Assertion `fp != (JNIFrameAddress)0' Now I dont know whether those two things are related. The only thing I know for sure is that I use the same cacheflush implementation for cacao and there it does its job (and fixes a real bug). Help! :) Regards Robert [0] - http://gcc.gnu.org/ml/java-patches/2007-q3/msg00112.html > Regards > Robert > > > > ------------------------------------------------------------------------ > > _______________________________________________ > kaffe mailing list > kaffe@kaffe.org > http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
