Hi,
the following patch is just multi-arch'ing IN_SOLIB_CALL_TRAMPOLINE.
The problem was that I need to overload that functionality for my
target but I didn't want to add a macro to the target specific
config file and multi-arching is the better approach anyway. I've
just added gdbarch.sh but not gdbarch.[ch] to the below patch.

2001-10-31 Corinna Vinschen <vinschen@redhat.com>
* arch-utils.c (generic_in_solib_call_trampoline): New function.
* arch-utils.h (generic_in_solib_call_trampoline): Extern declaration.
* gdbarch.c: Regenerated from gdbarch.sh.
* gdbarch.h: Ditto.
* gdbarch.sh (function_list): Add `IN_SOLIB_CALL_TRAMPOLINE' definition.
* infrun.c (IN_SOLIB_CALL_TRAMPOLINE): Remove macro.
