They are aliases as the operation is mostly identical (IIRC some might swap arguments), they are a different convention - why have the GCC convention? Because there's code that can be built against that expectation. The operations shouldn't be user visible per se - they are an implementation detail of the compiler. So we have aliases that can support code written against the standard.

Please update the commit message.
