whether can ignore 'source_text' in subprogram?
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!
