Thanks for the patch @JDPailleux 
In my opinion, having 3 options under inline family of directive will be more useful.

!dir$ inline
     This will be a hint to the optimizer
     By adding the "inlinehint" metadata on the call
!dir$ forceinline
    This should be used with caution.
    By adding the "alwaysinline" metadata on the call
!dir$ noinline
      By adding the "noinline" metadata on the call

This matches the pragma's supported by intel compiler as well [Below snippet from 
#pragma inline [recursive]
#pragma forceinline [recursive]
#pragma noinline
