There is some aspect of the Link-Time Optimization that I do not understand very well.
I've an iOS application with a massive use of C++11, in particular "regex" and "for_each with lambda functions". Some routines of this application are very time consuming. In example I've a routine that needs 3268 milliseconds to perform its task. As I told you before this routine is written in C++11 (I use -std=c++11 in Xcode settings)
Now Activating the LTO from Build Settings in Xcode I see that this time increase to 4002 milliseconds. This is contrary to my expectation of optimisation and do not understand why.
Any idea?
Thanks
Luca.
