83 -- Run-Time Globals --
84 ----------------------
86 -- This section documents the global variables that are passed to the
87 -- run time from the generated binder file. The call that is made is
88 -- to the routine Set_Globals, which has the following spec:
90 -- procedure Set_Globals
91 -- (Main_Priority : Integer;
92 -- Time_Slice_Value : Integer;
93 -- WC_Encoding : Character;
94 -- Locking_Policy : Character;
95 -- Queuing_Policy : Character;
96 -- Task_Dispatching_Policy : Character;
97 -- Restrictions : System.Address;
98 -- Interrupt_States : System.Address;
99 -- Num_Interrupt_States : Integer;
100 -- Unreserve_All_Interrupts : Integer;
101 -- Exception_Tracebacks : Integer;
102 -- Zero_Cost_Exceptions : Integer;
103 -- Detect_Blocking : Integer);
105 -- Main_Priority is the priority value set by pragma Priority in the
106 -- main program. If no such pragma is present, the value is -1.
108 -- Time_Slice_Value is the time slice value set by pragma Time_Slice
109 -- in the main program, or by the use of a -Tnnn parameter for the
110 -- binder (if both are present, the binder value overrides). The
111 -- value is in milliseconds. A value of zero indicates that time
112 -- slicing should be suppressed. If no pragma is present, and no
113 -- -T switch was used, the value is -1.
115 -- WC_Encoding shows the wide character encoding method used for
116 -- the main program. This is one of the encoding letters defined
117 -- in System.WCh_Con.WC_Encoding_Letters.
119 -- Locking_Policy is a space if no locking policy was specified
120 -- for the partition. If a locking policy was specified, the value
121 -- is the upper case first character of the locking policy name,
122 -- for example, 'C' for Ceiling_Locking.
124 -- Queuing_Policy is a space if no queuing policy was specified
125 -- for the partition. If a queuing policy was specified, the value
126 -- is the upper case first character of the queuing policy name
127 -- for example, 'F' for FIFO_Queuing.
129 -- Task_Dispatching_Policy is a space if no task dispatching policy
130 -- was specified for the partition. If a task dispatching policy
131 -- was specified, the value is the upper case first character of
132 -- the policy name, e.g. 'F' for FIFO_Within_Priorities.
134 -- Restrictions is the address of a null-terminated string specifying the
135 -- restrictions information for the partition. The format is identical to
136 -- that of the parameter string found on R lines in ali files (see Lib.Writ
137 -- spec in lib-writ.ads for full details). The difference is that in this
138 -- context the values are the cumulative ones for the entire partition.
140 -- Interrupt_States is the address of a string used to specify the
141 -- cumulative results of Interrupt_State pragmas used in the partition.
142 -- The length of this string is determined by the last interrupt for which
143 -- such a pragma is given (the string will be a null string if no pragmas
144 -- were used). If pragma were present the entries apply to the interrupts
145 -- in sequence from the first interrupt, and are set to one of four
146 -- possible settings: 'n' for not specified, 'u' for user, 'r' for
147 -- run time, 's' for system, see description of Interrupt_State pragma
148 -- for further details.
150 -- Num_Interrupt_States is the length of the Interrupt_States string.
151 -- It will be set to zero if no Interrupt_State pragmas are present.
153 -- Unreserve_All_Interrupts is set to one if at least one unit in the
154 -- partition had a pragma Unreserve_All_Interrupts, and zero otherwise.
156 -- Exception_Tracebacks is set to one if the -E parameter was present
157 -- in the bind and to zero otherwise. Note that on some targets exception
158 -- tracebacks are provided by default, so a value of zero for this
159 -- parameter does not necessarily mean no trace backs are available.
161 -- Zero_Cost_Exceptions is set to one if zero cost exceptions are used for
162 -- this partition, and to zero if longjmp/setjmp exceptions are used.
165 -- Detect_Blocking indicates whether pragma Detect_Blocking is
166 -- active or not. A value of zero indicates that the pragma is not
167 -- present, while a value of 1 signals its presence in the
