How to enable "Stack Consumption Computation"

[jayyjyang]

I read the help doc for Stack Consumption Computation, yet still not know how to enable this feature. How to use this option"using -StackConsumption" ? Details with screenshots will help a lot. Thank you very much.

It is documented in the manual (see attached screenshot).

Keep in mind that this way is for the HCS08 compiler/linker.

If you would like to do this say for ARM, see GNU Static Stack Usage Analysis | MCU on Eclipse 

I hope this helps,

Erich

Thank you, Erich. 

In fact, I have read the manual. Just can't find out a place to "enable the linker option". I have never do anything about "the linker option".

That means I am stuck at step 1(see attached screenshot).

Hey Alice,

Thank you. It helps a lot.

And now I am at step 3. It outputs this(see the attached here):

So no"STACK CONSUMPTION COMPUTATION"section in the MAP file, and no "Maximum Stack Usage is calculated for following path" as the manual shows:(see the attached above)

PS: BTW, what do the numbers mean in the "cpmu_init(3)(0)  ", and why there are two numbers?

[Alice_Yang]

Hello Yang,

- Please see the bottom of .map file , you will find  STACT CONSUMPTION .

- The meaning of numbers is :

• the first value after the function name represents the stack size required for calling that particular function from its caller (so basically the stack consumption of the ‘call’ itself)
• the second value after the function name appears only for the leaf functions (functions that don’t call other functions) and represents the stack size consumed by that function

Hope it helps

Have a great day,
TIC

Hi Alice,

Thank you for the information.

Yes, I have checked the whole MAP file, including the bottom, just not there. 

No STACT CONSUMPTION at all.

Any idea how would this happen?

PS: Here's the bottom of it.
