Generally, that is the case.  Direct non-inlined calls of
always_inline functions thus indicate that the destination become
known only after inlining in the optimization pipeline.  Without more
context, especially without knowing how exactly you call my_quicksort
function, it is impossible to say why.  If you cannot povide us with
the source code (I would be interested if you can), you can try
compiling with -fdump-tree-all -fdump-ipa-all-details and go through
the generated dump files to find out at what point it becomes known.
ipa-cp and ipa-inline dumps also contain information about what
inlining context of your function.


Thank you. I most certainly don't mind sharing all of the sources, they are just not in a refined state. I have a little time to import them into github now, but if I run out of time, I'll get them in later today.
