|
|
* Why not just use ifdefs?
|
|
* ifdefs tend to result in code that compiles on one platform but not another.
|
|
* Given the number of build and platform configurations we have, it's best to
|
|
* aim to compile the same on as many platforms as possible, and let the
|
|
* compiler see the constexprs and handle dead-code elision itself.
