M.1 Specific Documentation Requirements
In addition
to implementation-defined characteristics, each Ada implementation is
required to document various properties of the implementation:
The behavior of implementations in implementation-defined
situations shall be documented — see
M.2

procedure needs to accept for the Alignment parameter. How the standard
storage pool is chosen, and how storage is allocated by standard storage
pools. See

including a description of its period. See

time-dependent Reset procedure that is guaranteed to initiate different
random number sequences. See

D.5.1(14).

the completion of an aborted construct to be delayed later than what
is specified for a single processor. See
D.6(3).
The metrics for aborts. See
D.6(8).
The values of Time_First, Time_Last, Time_Span_First,
Time_Span_Last, Time_Span_Unit, and Tick for package Real_Time. See

The properties of the underlying time base used
in package Real_Time. See
D.8(34).
Any synchronization of package Real_Time with external
time references. See
D.8(35).
Any aspects of the external environment that can
interfere with package Real_Time. See
D.8(36/5).
The metrics for package Real_Time. See
D.8(45).
The minimum difference between the value of the
delay expression of a
delay_until_statement
and the value of Real_Time.Clock, that causes the task to actually be
blocked. See
D.9(8).
The metrics for delay statements. See
D.9(13).
The upper bound on the duration of interrupt blocking
caused by the implementation. See
D.12(5).
The metrics for entry-less protected objects. See
D.12(12).
The values of CPU_Time_First, CPU_Time_Last, CPU_Time_Unit,
and CPU_Tick of package Execution_Time. See
D.14(21/2).
The properties of the mechanism used to implement
package Execution_Time, including the values of the constants defined
in the package. See
D.14(22/2).
The metrics for execution time. See
D.14(27).
The metrics for timing events. See
D.15(24).
The processor(s) on which the clock interrupt is
handled; the processors on which each Interrupt_Id can be handled. See
D.16.1(32).
Whether the RPC-receiver is invoked from concurrent
tasks, and if so, the number of such tasks. See
E.5(25).
Any techniques used to reduce cancellation errors
in Numerics.Generic_Real_Arrays shall be documented. See
G.3.1(86/2).
Any techniques used to reduce cancellation errors
in Numerics.Generic_Complex_Arrays shall be documented. See
G.3.2(155/2).
If a
pragma
Normalize_Scalars applies, the implicit initial values of scalar subtypes
shall be documented. Such a value should be an invalid representation
when possible; any cases when is it not shall be documented. See

each unspecified effect. If the effects of a given erroneous construct
are constrained, the constraints shall be documented. See
