Let's say I have this enum:
[Flags] enum Letters { A = 1, B = 2, C = 4, AB = A | B, All = A | B | C, }

if((letter & Letters.AB) == Letters.AB)
Is there a simpler way to check if any of the flags of a combined...

And note that O_RDWR is exactly O_RDONLY | O_WRONLY
You can do something like this:

I use !=0 sparingly in boolean expressions.
I prefer the first one.
I prefer the first one because it's more readable.

Loop unrolling and inlining are specifically mentioned there since, although they make the code faster, they also make it larger .
There are many optimizations that a compiler can perform, other than loop unrolling and inlining .
