Extensible error symbol table
Registered by
Andrew Johnson
The error symbol table is not currently extensible; there's no way to load error symbols that are defined in support modules.
A module should be able to add its own errors to the IOC's error table at load time (this is better than creating an IOC-specific table at build time so we don't have to reimplement it if we later add dynamic loading of device support).

Whiteboard
If we make the M_xxx macros into global integer variables their usage in the S_xxx macros wouldn't have to change, we'd just assign a value to them on registration and the S_xxx values would get calculated from the M_xxx variable at run-time as needed. An initial value for the M_xxx variable could even be statically assigned and changed if necessary at init-time.
