<div>
<pre>MC currently accepts
zed = foo +2
call zed@PLT
but there is no way to represent that in ELF if foo is undefined. What is being
requested is that (on x86_64):
* we produce a R_X86_64_PLT32 with and addend of -4 to a PLT location.
* That the plt entry in turn should refer to foo+2.
It is the second part that cannot be represented. The entry will always just
refer to a symbol and there is no way to define a symbol that is some undefined
symbol + 2.</pre>
