That effort would be highly appreciated.

Errr, yes, but...  Wait, that's a good piece of sophistic dialectics!

*If* he needed those functions inline for performance, *then* it would be
a bug.  But since you never actually *need* something for performance but
rather just *long* for it.

I would say that it would be a (less severe) optimization issue.


What are those functions that aren't being inlined, even on Linux?  I just
checked the most obvious candidates by browsing the generated assembler
and they all appear inlined on my compilation using GCC-3.3.2 with "-O2

Let me also point out that the fact whether any function ends up being
inlined or not highly depends on how CXXFLAGS are set.  Namely the flags
-finline-limit=<n> --param max-inline-insns-single=<m1> --param
max-inline-insns-auto=<m2> --param max-inline-insns-rtl=<m3> do have a
significant effect, independent of the platform.

So, on your platform, the success of the whole compilation depends on such
tunable compiler parameters?  If that would be true it would be quite
