(clear_program_space_solib_cache): Declare. * progspace.c (release_program_space): Call clear_program_space_solib_cache. (clear_program_space_solib_cache): New function. * infrun.c (handle_inferior_event) : Call bpstat_stop_status. Use handle_solib_event. * breakpoint.c: Include gdb_regex.h. (print_solib_event): New function. (bpstat_print): Use print_solib_event. (bpstat_stop_status): Add special case for bp_shlib_event. (handle_solib_event): New function. (bpstat_what): Use handle_solib_event. (struct solib_catchpoint): New.
