can't answer all of your questions, but here goes:

you're right about the jump-table.  google / search docs for "GOT"
(global offset table).

the .o files aren't "raw machine code".  afaik, GCC uses an intermediary
language ("gimple") which allows creating programs/libs where different
TUs may be written in different languages (C, Ada, etc).  see the docs
on the '-flto' (link time optimisation) compiler and '-Wl,-flto' linker
options.
