jvmci return array

[Fotios Kounelis]

Hello,

I am trying to create a new native function inside jvmciRuntime.cpp. I 
want this function to return an integer array. While I have found on JNI 
a similar example with jintArray and SetIntArrayRegion() function, in 
the jvmci, the API is different.

I was able to return an integer and read it in the GraalVM compiler but 
I am struggling with an array. Would the program for jvmci be similar to 
the JNI? If yes, which is the equivalent of SetIntArrayRegion() for this 
API, assuming I have the code below?

jintArray result;
JRT_BLOCK_ENTRY(jintArray , JVMCIRuntime::object_hash_get(JavaThread * 
thread, jint * ar1))
   JRT_BLOCK;
     jintArray result;
     result = oopFactory::new_intArray(valueArraySize, CHECK_0);
     int* valueArray; //this is the array that contains the data to fill 
result
     // fill result with values in the thread
     return result;
     JRT_BLOCK_END;
JRT_END


Otherwise, could you give me an example of how to return an int array?

Best regards,

Fotis
