/* The following functions are provided for software stack checking.
|
||||
If hardware stack-checking is being used then the code can be
|
||||
compiled without the PCS entry checks, and simply rely on VM
|
||||
management to extend the stack for a thread.
|
||||
|
||||
The stack extension event occurs when the PCS function entry code
|
||||
would result in a stack-pointer beneath the stack-limit register
|
||||
value. The system relies on the following map:
|
||||
|
||||
+-----------------------------------+ <-- end of stack block
|
||||
| ... |
|
||||
| ... |
|
||||
| active stack |
|
||||
| ... | <-- sp (stack-pointer) somewhere in here
|
||||
| ... |
|
||||
+-----------------------------------+ <-- sl (stack-limit)
|
||||
| stack-extension handler workspace |
|
||||
+-----------------------------------+ <-- base of stack block
|
||||
|
||||
The "stack-extension handler workspace" is an amount of memory in
|
||||
which the stack overflow support code must execute. It must be
|
||||
large enough to deal with the worst case path through the extension
|
||||
code. At the moment the compiler expects this to be AT LEAST
|
||||
256bytes. It uses this fact to code functions with small local
|
||||
data usage within the overflow space.
|
||||
|
||||
In a true target environment We may need to increase the space
|
||||
between sl and the true limit to allow for the stack extension
|
||||
code, SWI handlers and for undefined instruction handlers of the
|
||||
target environment. */

@ to deal with the worst case function entry stacking (160bytes) plus

@ the stack overflow handler stacking requirements, plus the stack
|
||||
@ required for the memory allocation routines.
|

@
|

@ Normal PCS entry (before stack overflow check) can stack 16

@ preserving the stack under "sp" even on function return.
