score: Simplify _Terminate()
In _Terminate(), everything after invoking the fatal extensions is essentially dead code. Simplify this code block and provide a reasonable safe fall-back for badly configured applications. Just disable masked interrupts and execute an idle loop. Update #5067.

/**
|
||||
* @brief Initiates system termination.
|
||||
* @brief Initiates the system termination.
|
||||
*
|
||||
* This routine is invoked when the application or the executive itself
|
||||
* determines that a fatal error has occurred or a final system state is
|
||||
* reached (for example after exit()).
|
||||
* This handler is invoked to terminate the system. It is called by all
|
||||
* services which determine that a system termination is required. For
|
||||
* example, it is called by all higher level directives which announce a fatal
|
||||
* error like rtems_fatal() and exit().
|
||||
*
|
||||
* The first action of the system termination handler is to disable maskable
|
||||
* interrupts. This ensures that interrupts on this processor do not interfere
|
||||
* with the system termination procedure. This reduces the likelihood to end
|
||||
* up in a recursive system termination procedure.
|
||||
*
|
||||
* The second action of the system termination handler is to call the fatal
|
||||
* extensions of the user extensions.
|
||||
*
|
||||
* The fatal extensions are called with three parameters:
|
||||
*
|
||||
* - the fatal source,
|
||||
*
|
||||
* - a legacy parameter which is always set to false, and
|
||||
*
|
||||
* - an error code with a fatal source dependent content.
|
||||
*
|
||||
* The fatal extensions of the initial extension sets are invoked first. For
|
||||
* them, the following execution environment is required
|
||||
*
|
||||
* The first action of this function is to call the fatal handler of the user
|
||||
* extensions. For the initial extensions the following conditions are
|
||||
* required
|
||||
* - a valid stack pointer and enough stack space,
|
||||
*
|
||||
* - a valid code memory, and
|
||||
*
|
||||
* - valid read-only data.
|
||||
*
|
||||
* For the initial extensions the read-write data (including BSS segment) is
|
||||
* not required on single processor configurations. On SMP configurations
|
||||
* however the read-write data must be initialized since this function must
|
||||
* determine the state of the other processors and request them to shut-down if
|
||||
* necessary.
|
||||
* In uniprocessor configurations, the read-write data (including ``.bss``
|
||||
* segment) is not required. In SMP configurations, however, the read-write
|
||||
* data must have been initialized to determine the state of the other
|
||||
* processors and request them to shut-down if necessary. The board support
|
||||
* package (BSP) may install an initial extension that performs a system reset.
|
||||
* See the BSP documentation in the *RTEMS User Manual* for more information
|
||||
* how the system reset is done. The BSP provided fatal extension can be
|
||||
* disabled by the #CONFIGURE_DISABLE_BSP_SETTINGS application configuration
|
||||
* option. It is recommended to provide an application-specific fatal
|
||||
* extension using the #CONFIGURE_INITIAL_EXTENSIONS application configuration
|
||||
* option.
|
||||
*
|
||||
* Non-initial extensions require in addition valid read-write data. The BSP
|
||||
* may install an initial extension that performs a system reset. In this case
|
||||
* the non-initial extensions will be not called.
|
||||
* In certain error conditions, it may be unreliable to carry out the
|
||||
* following steps of the termination procedure since the read-write data may
|
||||
* be corrupt. One of the fatal extensions of the initial extension set should
|
||||
* reset the system to stop the system termination procedure.
|
||||
*
|
||||
* Once all fatal handler executed the system state is set to
|
||||
* SYSTEM_STATE_TERMINATED.
|
||||
* After invoking the fatal extensions of the initial extension sets, the fatal
|
||||
* extensions of the dynamic extension sets are invoked. For this procedure
|
||||
* valid read-write data is required.
|
||||
*
|
||||
* The final step is to call the CPU specific _CPU_Fatal_halt().
|
||||
* The last action of the system termination handler is to execute the CPU port
|
||||
* provided idle loop _CPU_Thread_Idle_body() with maskable interrupts
|
||||
* disabled. Please note, that properly configured applications should not
|
||||
* reach this point.
