In the HAL files why does #if defined(CAN1) exist and why is it not defined by default if I enable CAN1.

Using STM32CubeIDE.

Also when defined by user the autocomplete does not work on the IDE for those functions

Works for me on a new project in CubeMX.

If the symbol isn't defined, makes sense that autocomplete would not find it.

Even after I define CAN1 (and the IDE shows them as not gray (active)) they still don't show in the autocomplete. The project compiles even without the define.
