Do you plan to do it via libgcc/Makefile.in + gcc/libgcc2.c - and then use the
ME builtin?
That could be fun to try :)

I did LEADZ and TRAILZ, I guess I should do these. Assigning to me.

About POPCNT and POPPAR, beware! Implementations are much harder than simply
using the GCC __builtin_popcount{,l,ll}
Well, the difference is that one should be able to easily handle 128

I'm not working on this = unassign.

POPCNT and POPPAR are present in many other compilers
And (even) more interestingly they are part of the Fortran 2008 Candidate
Release (as you also mentioned):
13.7.128 POPCNT (I)

Tobias, Steven,
If you would like to usurp this request and use it to implement the complete
set
of F2008 bit intrinsics, please feel free to do so.
For completeness, one other HPF bit intrinsic is ILEN - which counts
