- *  one iteration of the loop body.  In this case, it might be desirable

- * Contexts
- *
- *  Generally there are 2 types of context to save.
- *     1. Interrupt registers to save
- *     2. Task level registers to save
- *
- *  This means we have the following 3 context items:
- *     1. task level context stuff::  Context_Control
- *     2. floating point task stuff:: Context_Control_fp
- *     3. special interrupt level context :: Context_Control_interrupt
- *
- *  On some processors, it is cost-effective to save only the callee
- *  preserved registers during a task context switch.  This means
- *  that the ISR code needs to save those registers which do not
- *  persist across function calls.  It is not mandatory to make this
- *  distinctions between the caller/callee saves registers for the
- *  purpose of minimizing context saved during task switch and on interrupts.
- *  If the cost of saving extra registers is minimal, simplicity is the
- *  choice.  Save the same context on interrupt entry as for tasks in
- *  this case.
- *
- *  Additionally, if gdb is to be made aware of RTEMS tasks for this CPU, then
- *  care should be used in designing the context area.
- *
- *  On some CPUs with hardware floating point support, the Context_Control_fp
- *  structure will not be used or it simply consist of an array of a
- *  fixed number of bytes.   This is done when the floating point context
- *  is dumped by a "FP save context" type instruction and the format
- *  is not really defined by the CPU.  In this case, there is no need
- *  to figure out the exact format -- only the size.  Of course, although
- *  this is enough information for RTEMS, it is probably not enough for
- *  a debugger such as gdb.  But that is another problem.

- *
- *  RTEMS guarantees that (1) will never happen so it is not a concern.

- *  which must logically operate together.  Bits in the _value are
- *  set and cleared based on masks built by _CPU_Priority_mask().

- *  and _Priority_Minor() are "massaged" by _CPU_Priority_bits_index()
- *  to properly range between the values returned by the "find first bit"
- *  instruction.  This makes it possible for _Priority_Get_highest() to
- *  calculate the major and directly index into the minor table.
- *  This mapping is necessary to ensure that 0 (a high priority major/minor)
- *  is the first bit found.
- *
- *  This entire "find first bit" and mapping process depends heavily
- *  on the manner in which a priority is broken into a major and minor
- *  components with the major being the 4 MSB of a priority and minor
- *  the 4 LSB.  Thus (0 << 4) + 0 corresponds to priority 0 -- the highest
- *  priority.  And (15 << 4) + 14 corresponds to priority 254 -- the next
- *  to the lowest priority.

- *      if _value > 0x00ff

- *        _number = 8;

- *      if _value > 0x0000f

- *        _number += 4

- *     swap least significant two bytes with 16-bit rotate
- *     swap upper and lower 16-bits
- *     swap most significant two bytes with 16-bit rotate

- *  an "endian swapping control bit" in the CPU.  One good reason is
- *  that interrupts would probably have to be disabled to insure that
- *  an interrupt does not try to access the same "chunk" with the wrong
- *  endian.  Another good reason is that on some CPUs, the endian bit
- *  endianness for ALL fetches -- both code and data -- so the code
