Hi David,

> What is the status of STABS support?

Essentially it is in maintenance mode.  But this is due to lack of 
developers interested in extending STABS support, rather than a policy 
of maintenance-only.

No, none.

No, they would be reviewed and, assuming that they are suitable, they 
would be accepted for inclusion in future releases.

Have you tried using a DWARF compression tool like dwz ?

Or maybe the --compress-debug-sections option to objcopy ?
