--- Comment #2 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
The implied split is 'code,data,tls-data' rather than 'functions,variables'
(there are constants too, which are not variables, but should be treated like
variables here; and TLS data does not rely on copy relocations).

Since the original option was intended to be used mainly in the negative form,
I think it may be less confusing to introduce

-f[no-]semantic-code-interposition
