Re: Interpreting bytecode on a powerpc 405 EP

["Patrick Olinet" <patrick dot olinet at gmail dot com>]

Before starting the daunting task of compiling a new toolchain, I
would like to get some clues whether it will work or not.

Is there anybody out there with a gcj cross toolchain targeting PPC405
that could do the test for me, that is compile and run a piece of code
that interpret java bytecode at runtime ? I could provide a sample
code if needed. The toolchain version should be one of the latest.

Thanks for your proposals.

Patrick
