[commit] Move find_frame_addr_in_frame_chain() to varobj.c

[Andrew Cagney <ac131313 at redhat dot com>]

Simple cleanup.  Move a function out of blockframe.c to the file that 
uses it.

Also adds (another) comment noting the need to switch to frame IDs.

commited,
Andrew
2002-11-23  Andrew Cagney  <ac131313@redhat.com>

	* blockframe.c (find_frame_addr_in_frame_chain): Move function
	from here ...
	* varobj.c (find_frame_addr_in_frame_chain): ... to here.
	(varobj_create): Note that frame ID should be used.
	* frame.h (find_frame_addr_in_frame_chain): Delete declaration.
