We already have -Winline that dumps same info for all functions marked

much, but I might be C centric where if I wanted to get something
inlined, I would use inline keyword :)
I must say I learned *a lot* about vectorization by having the
vectorizer report on *every loop* whether it could vectorize it or not.
A couple of weeks ago we handed off our code to an external reviewer.
He - using ifort - (as well as we, using gfortran), reported ~ 100,000
loops of which ~ 51 % were vectorized (he also categorized the
non-vectorized loops according to reason-not-vectorized (5 classes)).
If I were afraid of big numbers, I wouldn't work in meteorology :-)
[ PS, I finally constructed a dumbed down setup with the routines
GEMINI, HLPROG, PHCALL, PHTASK and SL2TIM. Amazingly, now
-flto -fwhole-program starts to *do* something: lto1 spend a
whole 25 seconds on processing this. ]
