Yes, yes, yes and yes. As to how you can do this, see ld info doc
node "Input Section Basics" for the answer to (1) and (2). For (3)
and (4) you're going to need to compile with -ffunction-sections then
write scripts to put the functions where you want them. An
alternative to (4) is to build a jump table at a fixed address then
define the function entry points on the jump table entries.
