want to have happen; but for very large programs, the startup time

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.

2001-01-26 Fernando Nasser <fnasser@redhat.com> Fix double parsing of filenames passed as command line arguments to GDB (causes weird handling of escape characters). Also, remove dependencies on the CLI from libgdb. * call-cmds.h: Remove declaration of exec_file_command(). * gdbcore.h: Remove declaration of exec_file_command(). Add declarations for exec_open() and exec_file_clear(). * symfile.h: Add declarations for symbol_file_add_main() and symbol_file_clear(). * exec.c (exec_open): New function. Implements to_open for exec targets. (exec_file_clear): New function. Makes GDB forget about a previously specified executable file. (exec_file_attach): Move parsing of arguments from here ... (exec_file_command): ... to here. (init_exec_ops): Use exec_open(), not exec_file_command() to implement to_open for exec targets. * symfile.c (symbol_file_add_main): New function. Call symbol_file_add() with default values. Used when the file name has already been parsed. (symbol_file_clear): New function. Makes GDB forget about previously read symbols. (symbol_file_command): Call the above function instead of inline code. * main.c: Include "symfile.h" and "gdbcore.h" instead of the deprecated "call-cmds.h". (captured_main): Call exec_file_attach() and symbol_file_add_main() instead of exec_file_command() and symbol_file_command(). (captured_main): Add comment. * corefile.c: Include "symfile.h". (core_file_command): Call symbol_file_add_main() instead of symbol_file_command(). (reopen_exec_file): Call exec_open() instead of exec_file_command(). * infcmd.c: Include "symfile.h". (attach_command): Call symbol_file_add_main() instead of symbol_file_command(). * infrun.c: Remove comment about the inclusion of "symfile.h", not any longer appropriate. (follow_exec): Call symbol_file_add_main() instead of symbol_file_command(). * remote-es.c: Include "symfile.h". (es1800_load): Call symbol_file_add_main() instead of symbol_file_command(). * remote-vx.c: Remove comment about the inclusion of "symfile.h", not any longer appropriate. (vx-wait): Call symbol_file_add_main() instead of symbol_file_command(). * solib-svr4.c (open_symbol_file_object): Call symbol_file_add_main() instead of symbol_file_command(). * v850ice.c (ice_file): Call exec_open(), exec_file_attach() and symbol_file_add_main() instead of exec_file_command() and symbol_file_command(). * Makefile.in: Update dependencies.
