Description Jonathan Larmour 2003-03-24 20:28:07 EST
This is an enhancement requested at FOSDEM 2003. Here's an excerpt from a
relevant mail:

  * Dynamic loading. A full blown implementation is of course quite large and a
can of worms. So two possibilities were suggested - a system similar to what
vxWorks does where objects are linked but still with relocs (essentially a .o
file) and linking at the time the .o is loaded by comparing with a built-in
symbol table and filling in the relocs (and adding newly exported symbols from
the new object to the symbol table too). Presumably some sort of init function
with a unique name to that object would want to be called too.

  A second possibility (and it isn't either/or - both are possible) would be a
very simple system using function pointer tables and stubs - for those who just
want dynamically updatable code rather than more complex dynamic loading.
