S/390 as GCC 4.3 secondary plattform?

[Andreas Krebbel <krebbel1 at de dot ibm dot com>]

Hello Mark,

sorry for tuning in so late to the GCC 4.3 primary/secondary 
plattform discussion.

As you probably expect I'll give a vote for s390-ibm-linux-gnu
and s390x-ibm-linux-gnu to be marked as gcc secondary plattforms.

I think the s390 back end is in a pretty good shape. The languages
c,ada,c++,fortran,java,objc and obj-c++ bootstrap fine and are tested
regularly. I've set up a gcc daily build posting the testresults of the
last 3 gcc branches every day.

We have a competent maintainer - Ulrich Weigand and 2 developers at IBM
(Wolfgang Gellerich and myself) who are able to spent at least a good part 
of their time working on the S/390 back-end fixing bugs, 
developing new features and providing support of new cpus.

In the criteria for primary plattforms I've read that primary plattforms
have to be "popular systems". Reading this as "widely used" I think that 
this will be a requirement which mainframes are unlikely to meet in the 
near future, so I propose to make s390 and s390x secondary plattforms for 
now. I think this can be important to show users that gcc works reliably on
S/390 and that it can be expected to do so in the future as well.

Bye,

-Andreas-
