Re: Synthetic target on linux x86_64 host

Can synthetic target even be built with native x86_64 tools?

I don't think so. Synth calls kernel system calls directly, using assembly language. I expect this part needs re-writing into 64 bit code.

That is a bit surprising - I assumed the synthetic target was just another application from the compiler's side.


Anyway it is good to have a clear answer. Thanks.

Also, eCos is very much used on 32 bit systems. I don't know of
anybody using it on 64 bit systems. You are bound to run into problems
with assumptions that sizeof(int)==4 etc. However synth probably is a
good platform to find and fix some of these, once you have done the
basic HAL port.

I don't know anything about the x86 or (shudder) x86-64 bowels and would prefer to live a long and sane life by keeping it that way :)
