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.
