whether can ignore 'source_text' in subprogram?

[ibertli]

Hello Sir, i have a question asking for your help. Based on my understanding，we cannot ignore 'source_text' in subprogram, but i found in '/ocarina-build/ocarina/doc/source/ping/devices.aadl' at line21 where the special subprogram has no 'source_text'. It confused me.
thanks for your replay!

What do you mean by "we cannot ignore source_text in source program"? A model is perfectly valid if subprograms do not define source_text. However it may not be correct for a specific model processing if absent. For instance, scheduling analysis does not need this property defined, but code generation does. Since code generation may not consider device, it is fine.

I do not understand. If i do code generation work use software component without 'source_text' in subprogram, how can i confirm which file to execute when call a subprogram and where is the function 'subprogram_b'? Example like this:

---

SUBPROGRAM subprogram_b
features
subb_port: in parameter Base_Types::integer;
PROPERTIES
SOURCE_LANGUAGE => (C);
SOURCE_NAME => "subprogram_b";
END subprogram_b;

I suggest you study the provided examples.

As I said;

• your example is perfectly valid if you perform scheduling. The Source_Text property is not necessar.
• your example is invalid for code generation: the name of the C file is missing and you cannot complete code generation

I know what's your mean. Aimed at code geration, i cannot ignore 'source_text'。Thanks very much!
