Re: [RFA] Introduce notion of "search name"

[Andrew Cagney <cagney@gnu.org>]

I.e., through out GDB there is the assumption that symtab internally 
uses simple strings.

We shouldn't.  Recalling that one of the underlying problems here was 
the need to construct search names on the fly using more complext debug 
info, we should instead have interfaces such as:


This is a worthy goal, but I see it as a goal separate from what the
patch is trying to achieve.
This is in part true.  The mistake is to seperate cleanups (or 
refactorings) from enhancements.  Enhancement and fixes needs to go 
hand-in-hand with a corresponding cleanups.  If we don't do this, we 
quickly find that those long over-due changes never occure.

If this, as an implementation detail, were to be strictly hidden behind 
the symtab interface, it wouldn't be a problem.  Unfortunatly, as I 
illustrated, the SYMBOL_*_NAME macros permieate GDB, so hand in hand 
with this change, should be changes to screw down that aspect of the 
symtab interface, and then have Ada use that.
