2001-02-21 Kevin Buettner <kevinb@redhat.com>
* solib.h (in_svr4_dynsym_resolve_code): Delete declaration.
(in_solib_dynsym_resolve_code): Add declaration.
(IN_SOLIB_DYNSYM_RESOLVE_CODE): Changed define to invoke
in_solib_dynsym_resolve_code() rather than
in_svr4_dynsym_resolve_code(). Also, removed the ifdefs
which caused this macro to only be defined when
SVR4_SHARED_LIBS is defined.
* solib.c (in_solib_dynsym_resolve_code): New function.
* solist.h (struct target_so_ops): Add new member
in_dynsym_resolve_code.
* solib-aix5.c (aix5_in_dynsym_resolve_code): Renamed from
in_svr4_dynsym_resolve_code. Also, made static.
(_initialize_aix5_solib): Initialize in_dynsym_resolve_code
member in aix5_so_ops.
* solib-svr4.c (svr4_in_dynsym_resolve_code): Renamed from
in_svr4_dynsym_resolve_code. Also, added second version
of this function which will be used when SVR4_SHARED_LIBS
is not defined.
(_initialize_svr4_solib): Initialize in_dynsym_resolve_code
member in svr4_so_ops.
* ia64-aix-nat.c, ia64-aix-tdep.c, config/ia64/aix.mh,
config/ia64/aix.mt, config/ia64/nm-aix.h, config/ia64/tm-aix.h,
config/ia64/xm-aix.h: New files.
* ia64-tdep.c (_initialize_ia64_tdep): Remove declaration.
(ia64_aix_sigcontext_register_address): New declaration.
(ia64_gdbarch_init): Provide for intialization of
sigcontext_register_address member of struct tdep when
on target is detected to be running AIX.
* config/ia64/linux.mt (TDEPFILES): Add ia64-aix-tdep.o to
this list.
2001-02-20 Kevin Buettner <kevinb@redhat.com>
* ia64-tdep.c (ia64_frameless_function_invocation): Implement.
