I pulled a Daniel Berlin last night (in a good way) and started
packing structures like a #4 train at rush hour.
'maint space' has gone from:
before: 99352576
after: 79478784
It would take a lot of time to merge these patches into gdb.
I would have to write up a road map, and then test the patches
one at a time (that is the hard part, regression testing stuff
like coff), then submit the patches one at a time to the
symtab maintainers.
Is this something worth pursuing?

I think it's worth pursuing. For large applications, a 20% savings in
space could mean the difference between being able to easily debug the
app and running out of memory (or running into swap).

Yes.
I think so, at least.

This will definitly help short term. Long term, to abuse an ad, "While
amazing, it's not sensational[sp?]". As David and Elena work through an
overhaul of the symbol table and a better understanding of what it
really needs to do is gained, a more radical approach can be taken.
