Thirdly, it should be noted here that if the intention is to provide support on Hercules based systems, that Hercules allows us to use the newer instructions introduced by the processor upgrades even though we are using processors that shouldn't, in theory, support them.
If Hercules is configured as an S/390 to keep the guest operating system (e.g. Linux) happy, is it possible to validate that a binary is completely safe to run on an S/370, i.e. contains no 390-specific features?
This doesn't apply to providing 31 or 64 bit addressing however, as considerable operating system support is required to handle these modes.
Although the OS/380 project appears to have made major progress on this. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
