Missing return types from C functions inside M3 model

[matteasu]

Setup:

• Rascal 0.34.1
• Clair 0.10.1
• Ubuntu 22.10 aarch64
• OpenJDK 17.0.7

Given a simple C program, such as:

#include <stdio.h>

int main(int argc, char argv[]){
    printf("Hello world!");
    return 0;
}

If I try to generate an M3 model using the proper createM3ModelFromCFile function, I can see no trace of the function return type or parameters type inside the declaredType field of the M3 model. However, these are present if the program is parsed using the createM3ModelFromCppFile function.

    "declaredType": [
        [
            "c+function:///home/matteoasuni/test.c/main(int,char.*)",
            "any"
        ]
    ],

"declaredType": [
        [
            "cpp+function:///home/matteoasuni/test.c/main(int,char.*)",
            {
                "returnType": {
                    "modifiers": [],
                    "baseType": "int"
                },
                "parameterTypes": [
                    {
                        "modifiers": [],
                        "baseType": "int"
                    },
                    {
                        "modifiers": [],
                        "type": {
                            "modifiers": [],
                            "baseType": "char"
                        }
                    }
                ]
            }
        ]
    ],
