They are equivalent to "catch load" and "catch unload" from CLI.
Rationale: GUIs might be interested in catching solib load or
unload events.
2012-11-16 Mircea Gherzan <mircea.gherzan@intel.com>
* Makefile.in (SUBDIR_MI_OBS): Add mi-cmd-catch.o.
(SUBDIR_MI_SRCS): Add mi/mi-cmd-catch.c.
* breakpoint.c (add_solib_catchpoint): New function that
can be used by both CLI and MI, factored out from
catch_load_or_unload.
(catch_load_or_unload): Strip it down and make it use the
new add_solib_catchpoint.
* breakpoint.h (add_solib_catchpoint): Declare it.
* mi/mi-cmd-break.h: New file.
* mi/mi-cmd-break.c: Include mi-cmd-break.h.
(setup_breakpoint_reporting): New function used for both
catchpoints and breakpoints.
(mi_cmd_break_insert): Use setup_breakpoint_reporting.
* mi/mi-cmd-catch.c: New file.
* mi/mi-cmds.c (mi_cmds): Add the handlers for -catch-load
and -catch-unload.
* mi/mi-cmds.h: Declare the handlers for -catch-load and
-catch-unload.
