That's a good point. I see no reason to make them public and I agree that it would be better to make functions static.

@fdedden Did you have a chance to look into this? Do you think this can be done without negative impact?

Dear Simon, thank you for the suggestion. Yes, it is indeed better to have these functions defined as static
. It forces the so called 'storage duration' to be as long as the execution of the program (which is what we want here). As you mentioned, adding static
to global functions keeps the function private to the execution unit (similar to a file in this case) as well.
The addition of the keyword has already been implemented in January for the 3.18 release of Copilot (see 6779d03) to comply with the MISRA C coding standard. It should suffice for you to upgrade to at least the 3.18 release.
Please let me know if you have any more questions.
Reference to the C99 standard, section 6.2.2 and 6.2.4: http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf.

I think I only added it for variables, not functions, didn't I?

No? The commit I mentioned (6779d03) adds static
to the generator and accessor functions, and omits the step
function (which is what we want).
The variables have been defined static since I wrote the first version of the C99 backend.
Let me also ping @simondlevy, since I forgot to do that in my initial reply.

You're right. I completely forgot! 😮

@simondlevy have you been able to try with the latest version?

I bought a new computer recently and installed Copilot on it following the instructions as usual. When I tried the heater example, the compiled C header still did make the declarations static.

But were functions static or not? That was the issue, wasn't it?
