Yes, currently our code generation is absolute crap, because we are
using ADDIL+LDO sequences for absolutely every DP or DLT
relative/indirect access.
Other BFD and GCC targets have optimizations to use 'short' data, bss,
got, and sometimes plt sections when possible. Long term I would
really like to implement this for hppa-linux.
I'm not at all sure how this is done though - can anyone point me to
some code or documentation that explains it?
