GNU C++ Alignment With Initializer List Possible?

[patrickjp93]

Is it possible to do what this code SHOULD do?

 

float velocities[8] __attribute__ ((aligned (__BIGGEST_ALIGNMENT__))) = { something, something, ...};

 

Note, I have tried all 3 available positiona for the attribute. None of them work, but I can't find anywhere in the gnu documentation that says you shouldn't be able to do this.

 

It would be incredibly wasteful to fill each element with preset values one after the other.

If you’re using C++11/14/1y/1z/1xyzzy, it should be doable. IIRC they added in static array declaration + initialisation for most all things in recent versions of ISO C++. Hell, you should be able to do jagged arrays and initialise hashmaps and all kinds of stuff. Not positive on everything though, but I’m fairly certain you can do that.

If you can find an example or provide one with perhaps my missing compiler flag, that would be great, because I'm coming up blank around the net.

Someone pointed me to the alignas keyword… have you thought of using that? It may solve your delimma, and a lot more elegantly than __attribute__ abhorrences.

Thanks a bunch! That did the trick.
