HCS12 weak attribute

MM158 — Mon, 01 Aug 2022 12:15:39 GMT

Hello,

I'm working with HCS12 in CodeWarrior 5.9.0, and i try to use "weak" function attribute.

I don't find any clear statement (or example) on HCS12, that this attribute is available or not.

If there is not, can you help me how can I find an alternative for it.

Can you help me on this subject?

Thanks in advance.

Hello,

I'm affraid that weak attribute is not supported by HCs12 Compiler/Linker. Could you possibly describe the issue you are trying to solve by using weak attribute? Perhaprs there might be some wokaround to achieve a similar link behavior.

Regards,

Stan

Hello again,

Thank you for your answer @stanish,

I want to test a function (e.g. source.c) and mock (by cmock) one of the functions that are called in source.c .

now I have two function with similar name (i.e. original version of function and its fake or mock),

in my test file (test.c) I want to weak the original version of function and use its mock.

how can I do this?

example:

/* source.c */

int func_1 (void)

{

int x = 1;

int y = 12;

int z = func_call_1 (x,y);

return z;

}

-----------------------------------------------------------------------

/* func_2.c */

int func_call_1(int x, int y)

{

//do somthing

}

-----------------------------------------------------------------------

now in my mock file I have also a fake function with the name of func_call_1,

how I can run func_call_1 in my mock and not in func_2.c ?

in a normal situation weak attribute could did it.

Hi,

I am not absolutely sure I understand but it leads me to conditional compilation. ifdef ifndef
