For the uninitiated, can you please provide some background
information and the need for this set of patches? Is it
related to the discussion in:

  http://gcc.gnu.org/ml/java-patches/2005-q1/msg00181.html

?

I think this definitely needs to be documented
in changes.html.

In the first part of this patch set, you say:

  This is patch 1 of 3 trying to fix the CNI plt problem
  currently causing lots of Java failures.

What failures? On a randomly picked recent message
for testresults on IA64, I see a lot of Java failures:

  http://gcc.gnu.org/ml/gcc-testresults/2005-05/msg01547.html

though I haven't been seeing anything like this on
i686-pc-linux-gnu for several weeks now. Are these the
failures you refer to?

Thanks in advance for answering my naive queries.

Ranjit.
