New branch: ia64-improvements-branch

[Diego Novillo <dnovillo at redhat dot com>]

This branch will act as a repository for new optimizations mostly meant to 
improve code generation on IA-64.  However, some of the work currently 
going on should help other targets as well.  For now, this will help 
independent contributors to have a common code base to work with.

The branch will be maintained by Robert Kidd.  I will be co-maintainer, 
mostly to help with the mechanics of keeping the branch up-to-date.  All 
the usual GCC contributing rules apply to the branch:

- Patches must be submitted to gcc-patches for review.
- Contributors must have a proper FSF copyright assignment on file.
- Discussions on design and implementation issues are to be held on
  the main GCC development lists (gcc@ and gcc-patches@).
- Messages discussing the branch should have [ia64-improvements] in the
  subject.

Folks who need SVN write access and already have an FSF assignment, please 
contact me.

The branch will follow mainline.  Merges from mainline will happen at 
regular intervals.  But only when mainline is in a sufficient stable 
state.

To get a copy of the branch, you will need an SVN client.  Some quick 
instructions:

$ svn checkout svn://gcc.gnu.org/svn/gcc/branches/ia64-improvements-branch
$ mkdir bld
$ cd bld
$ ../ia64-improvements-branch/configure --prefix=$HOME
$ make all install

The above will create a GCC binary in $HOME/bin.

Gerald, is this patch OK for svn.html?


Thanks.
