Adds some MI commands to catch C++ exceptions. The new commands are -catch-throw, -catch-rethrow, and -catch-catch, these all correspond to the CLI commands 'catch throw', 'catch rethrow', and 'catch catch'. Each MI command takes two optional arguments, '-t' has the effect of calling 'tcatch' instead of 'catch', for example: (gdb) -catch-throw -t Is the same as: (gdb) tcatch throw There is also a '-r REGEXP' argument that can supply a regexp to match against the exception type, so: (gdb) -catch-catch -r PATTERN Is the same as: (gdb) catch catch PATTERN The change in print_mention_exception_catchpoint might seem a little strange; changing the output from using ui_out::field_int and ui_out::text to using ui_out::message. The print_mention_exception_catchpoint is used as the 'print_mention' method for the exception catchpoint breakpoint object. Most of the other 'print_mention' methods (see breakpoint.c) use either printf_filtered, of ui_out::message. Using field_int was causing an unexpected field to be added to the MI output. Here's the output without the change in print_mention_exception_catchpoint: (gdb) -catch-throw ^done,bkptno="1",bkpt={number="1",type="breakpoint",disp="keep", enabled="y",addr="0x00000000004006c0", what="exception throw",catch-type="throw", thread-groups=["i1"],times="0"} Notice the breakpoint number appears in both the 'bkptno' field, and the 'number' field within the 'bkpt' tuple. Here's the output with the change in print_mention_exception_catchpoint: (gdb) -catch-throw ^done,bkpt={number="1",type="breakpoint",disp="keep", enabled="y",addr="0x00000000004006c0", what="exception throw",catch-type="throw", thread-groups=["i1"],times="0"} gdb/ChangeLog: * NEWS: Mention new MI commands. * break-catch-throw.c (enum exception_event_kind): Move to breakpoint.h.
