For GCC, ``-Wunused`` contains: ``` -Wunused-function Warn whenever a static function is declared but not defined or a non\-inline static function is unused. -Wunused-label Warn whenever a label is declared but not used. To suppress this warning use the unused attribute. -Wunused-parameter Warn whenever a function parameter is unused aside from its declaration. To suppress this warning use the unused attribute. -Wunused-variable Warn whenever a local variable or non-constant static variable is unused aside from its declaration To suppress this warning use the unused attribute. ``` For Clang, some of the diagnostics controlled by ``-Wunused`` are enabled by default: ``` Controls [-Wunused-argument](https://clang.llvm.org/docs/DiagnosticsReference.html#wunused-argument), [-Wunused-but-set-variable](https://clang.llvm.org/docs/DiagnosticsReference.html#wunused-but-set-variable), [-Wunused-function](https://clang.llvm.org/docs/DiagnosticsReference.html#wunused-function), [-Wunused-label](https://clang.llvm.org/docs/DiagnosticsReference.html#wunused-label), [-Wunused-lambda-capture](https://clang.llvm.org/docs/DiagnosticsReference.html#wunused-lambda-capture), [-Wunused-local-typedef](https://clang.llvm.org/docs/DiagnosticsReference.html#wunused-local-typedef), [-Wunused-private-field](https://clang.llvm.org/docs/DiagnosticsReference.html#wunused-private-field), [-Wunused-property-ivar](https://clang.llvm.org/docs/DiagnosticsReference.html#wunused-property-ivar), [-Wunused-value](https://clang.llvm.org/docs/DiagnosticsReference.html#wunused-value), [-Wunused-variable](https://clang.llvm.org/docs/DiagnosticsReference.html#wunused-variable). ``` These checks are all usefull. This PR aims to enable ``-Wunused`` without breaking code. Pull Request resolved: https://github.com/pytorch/pytorch/pull/150077 Approved by: https://github.com/zou3519, https://github.com/wdvr
