Any GCC Porting for microSPARC(v8) on VxWorks?

Any GCC Porting for microSPARC(v8) on VxWorks?

[Puff Chuang - 莊國禎]

Dear All,

I would appreciate if anybody could give me an advice to configure gcc
for the target of microSPARC cpu on VxWorks.
My host can be Windows or Linux.

Now we're using gcc 2.7.2 for developing embedded system with VxWork and
microSPARC,
but this version lacks lots of supports for C++ programming
(like "new" and "try/catch").
It seems that the new release of GCC 3.2.2 only supports VxWorks on PowerPC,
and lacks support to microSPARC.
Which would be the closest porting to microSPARC on VxWorks?

Thanks in advance,

Puff Chuang

If you are using the version of VxWorks shipped with Tornado 2.2, it
should be easy to write config/sparc/vxworks.h based on the current
config/rs6000/vxworks.h.  I will happily answer specific questions.

We are not interested in supporting earlier, non-ELF, VxWorks in
modern GCC.

Dear Sir,

I'm really happy to have your reply.
But...Does it really easy to do porting from Tornado 2.2 RS6000 config?
I thought RS6000 and microSPARC were totally different in architechure.

We want to run our application of VxWorks on microSPARC, but now use Tornado
2.0's complier.
But the complier (gcc 2.7.2) lacks lots of C++ support.
We have Tornado 2.2 ,but it doesn't support microSPARC.
Therefore I'd like to port the new gcc for our target.

Is that a hard work that I should not try?  or I can get the advice from
here?

It depends on your abilities and experience. You can likely get advice
from here, though I doubt that anyone is willing to do the work for you
:)
