There was a problem hiding this comment.
Notably missing but used in the code base:
__attribute__((always_inline)): This should be IMO a wrapper incompiler_hints.h. A compiler not supporting this will generate less efficient code (assuming this is actually sensibly used), but correct code, if this is ignored__attribute__((align(N)))/attribute((aligned(N))): There is now<stdalign.h>that providesalignas()and the_Alignas()` since C11, so no need to use an extension for this.
