## Description

Just as the title mentioned, `solc --gas` does not output a gas esitimation.
## Environment

- Compiler version: 0.8.27-develop.2024.6.25+commit.ce4be6e1.Darwin.appleclang
- Operating system: Macos M2 Sonoma 14.5

## Steps to Reproduce

```solidity
pragma solidity ^0.8.0;

contract Test {
uint[] array;

function testGasEstimation() public {
array.push(1);
}
}
```
Execute the above example and the output is

No gas estimation found.

No source file or test is named. Start by reproducing the issue with solc --gas and the supplied Solidity contract, then trace the compiler's gas-reporting path; done means the command prints a gas estimation for the contract.
