That is to say, binutils would need to be built using ./configure --target=mc68hc11 and then at run time use a command like: as -mm9s12z foo.s I suppose the reasons for deciding that was that this is how the S12X has been done. However, I'm having more and more misgivings about this. The S12X and S12Z have quite different instruction sets. So far as I'm aware, code for one of those processors cannot be run on the other. Having the two (actually five - that target already includes m68hc11, m68hc12, m9s12x and m9s12xg) instruction sets generated by the same binary means that extra run time conditions must be included, which of course will slow the assembler. It also introduces the risk of introducing bugs which might break the other existing targets. So I'm now thinking that a better option will be to target this as a completely new configuration option, eg: ./configure --target=s12z Is there any existing policy or precident in binutils for such decisions? J' I've heard no opinions for either case, so I'll do whatever I find easier to implement and seems to make sense to me ! J' -- Avoid eavesdropping. Send strong encrypted email.
