Allow enabling/disabling breakpoint location ranges When a breakpoint has multiple locations, like e.g.: Num Type Disp Enb Address What 1 breakpoint keep y <MULTIPLE> 1.1 y 0x080486a2 in void foo<int>()... 1.2 y 0x080486ca in void foo<double>()...

This patch adds shorthand for the above, by making it possible to specify a range of locations with the following syntax (similar to thread id ranges): <breakpoint_number>.<first_location_number>-<last_location_number> For example, the command above can now be simplified to: (gdb) disable 1.2-5 gdb/ChangeLog: 2017-11-07 Xavier Roirand <roirand@adacore.com> Pedro Alves <palves@redhat.com> * breakpoint.c (map_breakpoint_number_range): New, factored out from ...
