copy_loop_headers patch disappeared?!

[Arpad Beszedes]

Dear all,

According to the ChangeLog:
Wed Mar  5 15:45:40 CET 2003  Jan Hubicka  <jh@suse.cz>
	* toplev.c (rest_of_compilation):  Do duplicate loop headers when 
optimizing for size.

What was the reason for "&& !optimize_size" to disappear before
copy_loop_headers call in toplev.c:rest_of_compilation? The difference 
appeared between snapshots 20030303 and 20030310.

The original patch was introduced at:
2002-10-06  Richard Henderson  <rth@redhat.com>
	PR optimization/2960
	* toplev.c (rest_of_compilation): Don't copy_loop_headers if
	optimize_size.

And it prevented duplicate loop condition checking when optimizing for 
size (although it is faster but the generated code is smaller).

On our testbed it reduces code size by almost 2%, so I would be happy if 
it remained the previous version.

Regards,
   Arpad Beszedes
