Changes approved by kev@cygnus.com, ezannoni@cygnus.com, eliz@is.elta.co.il.
Changelog: 2001-10-27 Fred Fish <fnf@redhat.com> * symfile.c (auto_solib_add): Update comment to note that this variable is now just used as a boolean to control shlib autoloading, and clarify when it is used. * symfile.h (auto_solib_add): Ditto. * symfile.c (auto_solib_limit): New variable that holds the autoloading threshold instead of overloading auto_solib_add. * symfile.h (auto_solib_limit): Ditto. * irix5-nat.c (_initialize_solib): Change auto-solib-add variable from var_zinteger to var_boolean and update help. * osfsolib.c (_initialize_solib): Ditto. * pa64solib.c (_initialize_pa64_solib): Ditto. * solib.c (_initialize_solib): Ditto. * somsolib.c (_initialize_som_solib): Ditto. * xcoffsolib.c (_initialize_solib): Ditto. * pa64solib.c (pa64_solib_total_st_size): Update comment to note that the new auto_solib_limit variable is used instead of overloading auto_solib_add variable. (_initialize_pa64_solib): Ditto. * somsolib.c (som_solib_total_st_size): Ditto. (_initialize_som_solib): Ditto. * pa64solib.c (_initialize_pa64_solib): Add new set/show commands for auto-solib-limit variable. * somsolib.c (_initialize_som_solib): Ditto * pa64solib.c (add_to_solist): Check that auto_solib_add is set and use auto_solib_limit as the threshold size instead of auto_solib_add. * somsolib.c (som_solib_add): Ditto, and also change warning text about size threshold exceeded. doc/ChangeLog: 2001-10-28 Fred Fish <fnf@redhat.com> * gdb.texinfo (auto-solib-add): Change docs to match implementation change. (auto-solib-limit): Add docs for new variable.
