--- Comment #7 from Adrien Guinet <adrien at guinet dot me> ---
>From my understanding of
https://gcc.gnu.org/onlinedocs/gcc/Variable-Attributes.html, the "aligned"
attribute inside a structure aligns the object inside this structure, and
nothing more, as the example says:

"You can also specify the alignment of structure fields. For example, to create
a double-word aligned int pair, you could write:

          struct foo { int x[2] __attribute__ ((aligned (8))); };


This is an alternative to creating a union with a double member that forces the
union to be double-word aligned. "

If I create a union, there is no alignment information. Anyway, I'd be happy to
read the official definition if it is specified somewhere!

Thanks!
