Inlining is driven by heuristics. See ipa-inline.c. Heuristics cannot be
perfect for all applications, of course. The current tuning of the heuristics
is based on SPEC2k scores on Opteron, i.e. mostly for programs

Form the gcc manual:
-finline-limit=n
... . The default value of n is 600. ...
This does not seem accurate: ddx and ddy are inlined for n=318, but not for
n=317 (corresponding respectively to 2.7s and 1.6s for the

The code in comment #3 is indeed inlined, but some cases are not. For instance
