[edk2-devel] [PATCH] CryptoPkg/FltUsedLib: Add FltUsedLib for float.

[Michael D Kinney]

Hi Sean,

This lib defines a global variable that is referenced when a compiler detects use of float/double types.  If the global is not referenced, then it should be optimized away, so the size impact should be zero.  That can be verified as part of the review of this feature.

Does anyone know off hand if defining this and enabling floating point has any negative side effects if you don't need it?  Size? Optimization? Other?   That is my only concern for enabling in all modules which is why the initial proposal was for a new library.
