supplement, treeshake.annotation in rollup includes both @__PURE__, @__NO_SIDE_EFFECTS__ https://rollupjs.org/configuration-options/#treeshake-annotations

Going through Rolldown's SideEffectDetector and Rollup's treeshake configuration, oxc's side effect detector should also include

  • https://rollupjs.org/configuration-options/#treeshake-manualpurefunctions
  • https://rollupjs.org/configuration-options/#treeshake-unknownglobalsideeffects

So we can eventually merge the two implementations and provide a unified functionality.
