What should be placed in the instruction data?

Problem

I replaced hello_solana_program.so with my own C.so in integration_test.rs, but the execution failed. My command is as follows:

contract C {
    function f() public pure returns (uint r1)
    {
        uint8 a=0;
        r1=a+1234;
    }
}

solang compile --target solana C.sol --output ./output

replace hello_solana_program.so with C.so, then perform test and print result

cargo test --package solana-svm --test integration_sbw_test -- svm_integration --exact --show-output

there is error:

Analyze

I suspect the error is caused by not assigning a value to the data field of the instruction, but I'm not sure what value should be assigned, shown in code

instructions: vec![CompiledInstruction {
    program_id_index: 1,
    accounts: vec![],
    data: vec![],
}],
