--- Comment #21 from H.J. Lu <hjl.tools at gmail dot com> ---
(In reply to Rafael Ávila de Espíndola from comment #20)
> Note that while the assembler change is a nice improvement, the original
> issue still exists.
>
> In the testcase that I attached before, the call to foo is now assembled to
> R_X86_64_PLT32, but
>
> .long foo - .
>
> Still produces a R_X86_64_PC32 as it has to.
>
> Since foo has default visibility, the linker could create a canonical plt
> entry to be the runtime address of foo.
