Data typesTypes.h
LinAsm libraries define their own data types. They are separated into two categories: scalar and vector data types. Scalar types are just aliases to internal C and C++ types and have the same length and operations set. Vector types are custom types, which use gcc aggregates to hold vectors. LinAsm also define union types which can hold both types simultaneously. They are useful when you apply vector operations to the data, but also need to extract some elements of target vectors.
