I think __attribute__((always_inline)) is used to inline functions
even not optimizing. Below is from GCC manual:
always_inline
Generally, functions are not inlined unless optimization is
specified. For functions declared inline, this attribute inlines the
function even if no optimization level was specified.
That just means that it's inlined under the implicit default
optimization level -O1 (that is what you get "if no optimization level
was specified"). If you set -O0, it will not inline. I had problem where
-O0 broke code that is depended on being inlined.
Best regards.
