Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.

In particular CPU_INTERRUPT_NUMBER_OF_VECTORS and
CPU_INTERRUPT_MAXIMUM_VECTOR_NUMBER are only used on
Simple Vectored Architectures, so do not depend on
them being defined. This disables as much as possible
that is specific to the Simple Vectored Model and
not expected to be used on architectures which use
the Programmable Interrupt Controller model for
interrupt handler vectoring.

The implementation of RBTree_Next was using an awkward construction to detect
and avoid accessing the false root of the red-black tree. To deal with the
false root, RBTree_Next was comparing node parents with the control node.
Instead the false root can be detected by checking if the grandparent of a
node exists; the grandparent of the tree's true root is NULL by definition
so the root of the tree is found while walking up the tree by checking for
the non-existence of a grandparent.
This change propagates into the predecessor/successor and iterate functions.

When inserting to a red-black tree with duplicates the min and max pointers are
not updated properly. We need to check the key of the min/max node against the
insert node since the insert point could be the child of a node with an
identical key to the min/max node.
|
|
|
|
|
|
| |
During node extraction from a red-black tree the min and max values are updated
incorrectly. We need to use the successor/predecessor functions to find the
next/previous node when we remove the min/max from the tree.

Make default for rtems_rbtree functions be unprotected (preemption enabled)
unless an unprotected variant e.g. rtems_rbtree_xxx_unprotected is available.

The increase of the stack size by CPU_STACK_ALIGNMENT in
_Thread_Stack_Allocate() is disadvantageous. This may lead to a huge
over allocation for specialized stack allocators. The
CPU_STACK_ALIGNMENT is at most 16 on all current RTEMS CPU ports. The
mimimum stack size ensured by _Stack_Ensure_minimum() must be
considerable larger than this value, otherwise stack overflows will
likely occur. Thus the _Stack_Adjust_size() is also superfluous.

This commit covers at least PR2020, 2022, and 2023. This
patch adds all of the code for both BSPs, modifications
to libcpu/powerpc for the ppc440, and some updates to the
BSPs from follow up review and testing.
These BSPs should be good baselines for future development.
The configurations used by Ric are custom and have a non-standard
NIC. They also do not have a UART. Thus the current console
driver just prints to a RAM buffer.
The NIC and UART support are left for future work. When the UART
support is added, moving the existing "to RAM" console driver to
a shared location is likely desirable because boards with no debug
UART port are commonly deployed. This would let printk() go to RAM.

This fix is critical. The previous implementation leads to system
corruption.

integer keys.

Add the trap vector to the interrupt frame. Also rename the assembly
macro that accesses the field to be consistent with similar macros.

Add a red-black tree helper method to ease obtaining the direction opposite
to the current direction. Useful for manipulating and traversing an rbtree.

Various tests must check program paths that result due to failed memory
allocations from the heap. To avoid tinkering with internal heap
structures throughout the test code these functions should be used.
