[ECOS] GCC and XScale

[Cristiano Ligieri Pereira]

Only xscale-elf-* should be used to build applications to an XScale board?
Can I generate xscale-elf-* from gcc-2.95.2? Do I need to download GCC
3.0? What's the best version of GCC to generate xscale-elf-* binaries? Or
arm-elf-* should work?

Some clarification on these issues are very welcome. :-)

Thanks,
Cristiano.

You can build arm-elf-* and they'll work fine on Xscale.  You won't
get pipeline optimizations and access to any of the new opcodes in 
ARMv5 though.

If you do want those, try the tools at
http://www.intel.com/design/intelxscale/dev_tools/

I haven't tried these _particular_ versions myself, so I don't know for
sure how well they work (I know the ones we are using internally are fine,
but Intel may still be distributing an older version). If they do work
well, let us know!

I've done all my port and also I've been compiling and running eCos
applications without any problem using this version of the XScale
compiler.

This is just to let you all know :-).
