--  This package provides set of Intel's specific data types for MMX/SSE/AVX
--  instruction sets. Children packages provide operations on this types,
--  one child package covers one instruction set. Types declarations are
--  specific for GNAT compiler. The way how subprograms are defined is also
--  GNAT specific, it allows to highly optimize code and replace one function
--  by one instruction in most cases.
