Thanks a lot.

BTW, unrelated to this,
what do you think should be done in the new ABI with garbage collection of
.opd entries (.opd entries for functions not exported from a binary
or shared library and whose address is never taken don't need to be persent)?
In the old ABI it would be enough just to kill the .opd entries,
but in the new ABI if the .opd entry is removed, suddenly debugger
(and objdump -d) will not know anything about the function.
Should such operation move the non-dot symbol to the actual function
body in that case (in addition to removing the unneeded .opd entry)?
