Re: Strict aliasing blog-post

In general, yes.
But: This is really compiler dependent.


A better approach would be to go through the code base, and rework the problematic code,
step by step.

And when this is done, have a look if there are „volatile“ missing,
and/or if we need better support for multi-core, like synchronizing the L2 caches
on some ARM platforms.
(But I’m not sure, if anybody is running EPICS on this kind of hardware)

It may be good enough to enable it for gcc, if version >= 5.
And what about clang ?
