Hi, I'm pleased to announce the release of JamVM 1.2.0 (http://jamvm.sourceforge.net). The following changes have been made since 1.1.4:
- Substantially rewritten the interpreter to use "stack-caching". This is an optimisation to eliminate most of the intermediate loads and stores to the operand stack. On desktop PowerPC (e.g. PPC750fx, MPC7447 with large, on-chip L2 cache at full processor speed) it achieves a speed increase of between 15 and 30%. On ARM (XScale PXA250) it achieves a speed-up of 50%. Unfortunately, due to the addressing modes of the IA32 (Pentium, etc.) and the code produced by gcc, it is actually slower than the old interpreter! Because of this, stack-caching is disabled by default on IA32. - Zip/Jar support is implemented in the bootstrap class loader. This means glibj.zip no longer needs to be unzipped. This includes resources. - Fix for edge-conditions in floating-point to integer conversion (floating- point value greater than int/long range). - Fix for very large array allocation, where the required memory overflows a 32 bit int (fixes the SEGV with Mauve). - Several other minor bug-fixes (e.g. ExceptionCheck was missed out of the JNI i/f table). As usual I'd like to thank Mark Wielaard for testing pre-releases. Thanks, Rob. _______________________________________________ Classpath mailing list [EMAIL PROTECTED] http://lists.gnu.org/mailman/listinfo/classpath
