NOTE: The RED zone is used for stack saftey checking. With stack above heap,
|
||
|
|
the heap will not be allowed to get within STKRED bytes of the current value
|
||
|
|
of the SP, if limit checking is enabled (see the cc +b option), SP isn't
|
||
|
|
allowed any closer than STKRED bytes to the top of the heap. If stack below
|
||
|
|
heap and limit checking is enabled, SP isn't allowed any closer than STKRED
|
||
|
|
bytes to _Utop. Minimum stack size = 2*_STKRED. Minimum value for STKRED
|
||
|
|
should be about 256 bytes. This allows some margin to issue DOS calls and
|
||
|
|
allow interrupt handlers to execute. (Some people think that this should
|
||
|
|
be > 1k.) */
