Representing entering inlined functions
As proposed by the format, information about the function that is about to be jumped into will be attached to the jump instruction itself. In case of inline-ed functions we don't have the jump instruction to rely on, so we should try to find an another way to represent it if possible.
One of the possible solutions could be data "in between" instructions, adding additional information. This could also handle the end (return) of inline functions, since that jump is also removed.
This topic requires additional discussion, particularly on finding ways of representing parts of code that are affected by inline functions and identifying ways to calculate arguments to the function being inline-ed.
