Hi Chris,

I think you might be looking for google perftools.
See:
  1. https://github.com/prasunanand/gperftools_d/
  2. https://github.com/gperftools/gperftools

I have been using gperftools_d a lot to profile my code and 
optimize.It generates really
cool 
[graphs](https://github.com/prasunanand/gperftools_d/blob/master/examples/profile.pdf).

If you need PGO, you can look here for reference:
https://github.com/prasunanand/faster_lmm_d/blob/master/Makefile#L122

Let me know if this helps or you face any issues using 
gperftools_d.
