I'm not sure just what you are proposing.  mark_target_live_regs does
use end_of_function_needs in the places where I would expect: at the
end of a function and at a return statement.  Otherwise it uses the
registers live at the start of a basic block, and then walks through
the block computing them.  That all looks right to me.

Perhaps I should ask: why is the register considered to be dead?
