#53 s390x port of ATLAS (against git from 9.9.2011)

here is an updated Patch. I reduced the number of subarchitectures to z9,z10 and z11.

These archs differ in several aspects so I decided to not merge these. Since I dont have access to the very old z900 and z990, I removed these.

  • This patch has been applied to basefiles, can close after release & confirmation.

     
  • OK, we are now getting close to stable. I have a couple of questions:
    (1) Can you update your archdefs to work with gcc 4.7.0?
    (2) Are you willing to do testing on this platform?

    Thanks,
    Clint

    I'm taking over responsibility for this port. Regarding your questions:
    (1) Yes, I'll update the archdefs to work with gcc 4.7.0.
    (2) Sure, I will perform testing. Is there any particular procedure to follow?

     
  • Great news on the 4.7. I've got most other platforms updated to gcc 4.7 for the stable.

    For testing, you first make sure you can pass "make check" and "make ptcheck". Once this is done, then you attempt to pass Antoine's test scripts, which can take a long time. You can invoke them by "make full_test". At the end, it'll print a summary showing any failures; if you miss this info, you can get it back by "make scope_full_test".

    If all this passes, then we can run the lapack testers, as long as lapack installs OK using the --with-netlib-lapack-tarfile. If you want to run these tests, I suggest installing with lapack 3.3.1 rather than 3.4.0 (3.4.0 has some bad errors).

    The lapack testers have more subtleties, so lets tackle gcc 4.7 and full_test first, if that sounds OK with you.

    Thanks!
