Detailed Description

This file defines types that match the CPU's native register.

tt::register_signed_long and tt::register_unsigned_long are double the size of a native register; the double size integers are often the results of a single CPU instruction.

For example the x86-64 instruction MUL can multiply two 64 bit integers together, the result is placed in two 64 bit register. DIV can divide a 128 bit integer in two registers by a 64 bit integer, with a 64 bit integer result.
