well, for me it boils down to a dependency problem, which is still a bit
tricky at the moment.
what i would like to see is:
32-bit hpux targets will build only solib-som.*, and only support 32-bit
debugging
64-bit hpux targets will build both solib-som.* and solib-pa64.*, and
support both 32-bit and 64-bit debugging
the problem in this scenario is that in the common hpux file (i.e.
hppa-hpux-tdep.c), in order to support both configurations, we cannot
refer to anything that is in solib-pa64.*.
this is already a problem if i need to call e.g. pa64_solib_select (),
and it becomes worse if we expose the solib methods to the tdep file.
i'm thinking that the best way to do this is:
- have the 32-bit hpux configs define PA_SOM_ONLY (as they do now)
- unconditionally build both solib-som.c and solib-pa64.c into all hpux
targets
- in solib-pa64.c, make everything compile out if PA_SOM_ONLY is
defined, except for a stub pa64_solib_select ()
is there a cleaner way?
