------- Additional Comments From hjl at lucon dot org  2004-04-06 17:49 -------
ia64_encode_section_info was removed in:

http://gcc.gnu.org/ml/gcc-patches/2003-04/msg01251.html

and added back in

http://gcc.gnu.org/ml/gcc-cvs/2003-08/msg00259.html

But the new code doesn't handle global register variables.

OK.  This should be sent to gcc-patches if it hasn't been sent there yet.

This needs approval from Mark Mitchell before it can be added to the 
gcc-3.4 branch.  I can only approve it for mainline at this time.
