Hello,

This patch generalizes the per-symbol location_funcs, replacing them 
with a symbol_ops vector (the contents are unchanged).  The patch 
doesn't change the size of the symbol.

As the comment hints:

+  /* NOTE: cagney/2003-11-02: The fields "aclass" and "ops" contain
+     overlaping information.  Since GDB has only a small finite number
+     of symbol classes it should be possible to merge the two fields
+     into a single ops-table "index".  Each entry providing both the
+     "ops" and the "aclass" values.  Doing that would shave 32 bits
+     off every symbol.  */

The patch sets us up for a more significant change - merge "ops" and 
"aclass" - and hence eliminates 32 bits (or 20%) of each symbol.  I 
should note that right now the details of the merge are "left as an 
exercise for the reader".

ok?
Andrew

PS: Hmm, better make certain I tested this on a dwarf2 system.
