Clearly personal judgment played a role. However, the tools are
reasonably task focused, and I did take basic steps to ensure
the benchmark data and tests were separate from the training

Great, thanks for the details, I agree.
Hope it's useful for others to see these details.
(btw, did you also check the performance gains when using the
profile of the benchmark itself, to learn about the upper-bound
of PGO for your program?)
I'll merge the IR PGO addition into LDC master soon. Don't know
what difference it'll make.
