Just hazarding a guess (a practice I learned from Dewar), but some of
the patches to gcc-2.7.2 distributed with gnat-3.09 break optimization
for the HPPA.

You haven't purchased support from ACT.

You can try gnat-3.10p, but some of my initial testing shows that the
patch file distributed with gnat-3.10p still suffers from broken
optimization on this architecture.  If those patches are integrated in
gcc-2.8 (as the patch file claims), then perhaps optimization will be
better when it's finally released and a gnat based on it is made
available.

Otherwise, try all optimization options on each source file and use
the resulting binary that works best.
