 * @deftypefun jit_debugger_breakpoint_id_t jit_debugger_add_breakpoint (jit_debugger_t @var{dbg}, jit_debugger_breakpoint_info_t @var{info})
 * Add a hard breakpoint to a debugger instance.  The @var{info} structure
 * defines the conditions under which the breakpoint should fire.
 * The fields of @var{info} are as follows:
 *
 * @table @code
 * @item flags
 * Flags that indicate which of the following fields should be matched.
 * If a flag is not present, then all possible values of the field will match.
 * Valid flags are @code{JIT_DEBUGGER_FLAG_THREAD},
 * @code{JIT_DEBUGGER_FLAG_FUNCTION}, @code{JIT_DEBUGGER_FLAG_DATA1},
 * and @code{JIT_DEBUGGER_FLAG_DATA2}.
 *
 * @item thread
 * The thread to match against, if @code{JIT_DEBUGGER_FLAG_THREAD} is set.
 *
 * @item function
 * The function to match against, if @code{JIT_DEBUGGER_FLAG_FUNCTION} is set.
 *
 * @item data1
 * The @code{data1} value to match against, if @code{JIT_DEBUGGER_FLAG_DATA1}
 * is set.
 *
 * @item data2
 * The @code{data2} value to match against, if @code{JIT_DEBUGGER_FLAG_DATA2}
 * is set.
 * @end table
 *
 * The following special values for @code{data1} are recommended for marking
 * breakpoint locations with @code{jit_insn_mark_breakpoint}:
 *
 * @table @code
 * @item JIT_DEBUGGER_DATA1_LINE
 * Breakpoint location that corresponds to a source line.  This is used
 * to determine where to continue to upon a "step".
 *
 * @item JIT_DEBUGGER_DATA1_ENTER
 * Breakpoint location that corresponds to the start of a function.
 *
 * @item JIT_DEBUGGER_DATA1_LEAVE
 * Breakpoint location that corresponds to the end of a function, just
 * prior to a @code{return} statement.  This is used to determine where
 * to continue to upon a "finish".
 *
 * @item JIT_DEBUGGER_DATA1_THROW
 * Breakpoint location that corresponds to an exception throw.
 * @end table
 * @end deftypefun
