    +This note requests inliner to inline this function irrespective of +inlining size threshold for this function. +

  • inline=Never +

    +This note requests inliner to never inline this function in any situation. +This note may not be used together with inline=Always note. +

  • opt-size +

    +This note suggests optimization passes and code generator passes to make +choices that help reduce code size. +
