Cosmic Compiler @stackfunction qualifier. (STM8 LIN Driver)

Hi.  Trying to find out what, if anything, the STM8 compiler does with the @stack function qualifier.  The STM8 LIN Driver uses @stack quite a lot, however it is not documented in the Cosmic STM8 User Manual.

Thanks

Colin

Hi,

@stack means that the function uses the actual stack, and not the simulated one.

This was meaningful in the past (st7), but it's irrelevant for stm8, where all functions use the real stack.

Regards.

Thanks for your reply.  Does the compiler ignore the qualifier?  I ask this because we would prefer not to modify the ST LIN Driver.  Modifying the supplied driver becomes a maintainence (and hence a quality assurance) issue.

Hello,

yes, the @stack qualifier is simply ignored by the compiler.
