--- Comment #9 from Jeffrey A. Law <law at redhat dot com> ---
Also note that on some targets indirect calls have a different ABI than calls
to named function. SO changing between direct and indirect calls is strictly
forbidden on some targets.
I suspect there's some magic we need to replicate in postreload-gcse from
cse/gcse/combine to prevent this from occurring unnecessarily.
