|\ \ | | | | | | Use (and ignore) the expression provided to log_assert in NDEBUG builds
| * | Use [[maybe_unused]] instead of YS_ATTRIBUTE(unused).whitequark2020-06-192-10/+18
| | | | | | | | | | | | | | | [[maybe_unused]] is available since C++17, so this commit adds a polyfill YS_MAYBE_UNUSED. Once we require C++17 we can drop it.

| | | | | | | | | | | | | | | This avoids warnings in NDEBUG builds emitted when a variable is only used in log_assert, but is always defined.
