Hi Everyone,
The library used to have the following macro:
#if (_MSC_VER == 1300) || defined(__INTEL_COMPILER) ||
defined(__BORLANDC__)
# define CRYPTOPP_CONSTANT(x) enum {x};
#else
# define CRYPTOPP_CONSTANT(x) static const int x;
#endif
There's a few key differences between 'enum' and 'static const'. One of
them is an enum takes no space in a class object, while static int's have
space allocated for them. Enums result in smaller objects at runtime.
I tested some code that uses enums rather than ints, and the code was
measurable faster:
# define CRYPTOPP_CONSTANT(x) enum {x};
The change was checked in at
https://github.com/weidai11/cryptopp/commit/953252e44d25ce82.
If you are working from Master then please rebuild the library.
Jeff
