C54x port: some general technical questions

[Jonathan Bastien-Filiatrault]

Hello every one,
    Me and Brian Richter are in the early development stage of the TI
C54x DSP port of GCC. We have some technical/project management questions. I'll
keep it short, so here it is:

* How do we officially become maintainers of this port ? We are presently in the 
process of filling out the copyright assignment forms. We have some code but it 
is far from complete. I was thinking of having a development branch in the main 
CVS tree that would get merged into mainline when ready.

* We have defined BIT_PER_WORD to 16 and UNITS_PER_WORD to 1. On this
DSP, there are two 40-bits accumulators. How do we make GCC take
advantage of this and which machine mode do we use ? I do not think
using HImode for these registers would be the best thing. Would a "custom" mode 
be necessary ? Suggestions welcome.

Thank you for your time,
    Jonathan
