Set a breakpoint for an address range.
break-range START-LOCATION, END-LOCATION
where START-LOCATION and END-LOCATION can be one of the following:
LINENUM, for that line in the current file,
FILE:LINENUM, for that line in that file,
+OFFSET, for that number of lines after the current line
or the start of the range
FUNCTION, for the first line in that function,
FILE:FUNCTION, to distinguish among like-named static functions.
*ADDRESS, for the instruction at that address.
The breakpoint will stop execution of the inferior whenever it executes
an instruction at any address within the [START-LOCATION, END-LOCATION]
range (including START-LOCATION and END-LOCATION).
