Move of a local object prevents copy elision

[dpiparo]

Hi,

the file include/blond/fft.h presents at line 340 an issue.
A move of a local object is in place which prevents copy elision: http://www.cplusplus.com/forum/general/186411 .
To avoid performance hits, one might consider to simply return the collection.

Cheers,

@dpiparo I really wasn't aware of that issue, commit c34ee86 is taking care of this

Hi @kiliakis,

thanks. Do you see an effect when profiling before and after c34ee86?

Cheers,
