x86-64 is the 64-bit extended architecture of x86, its Legacy Mode preserves the entire and unaltered x86 architecture.
This is a list of x86 calling conventions. These are conventions primarily intended for C/C++ compilers (especially the 64-bit part below), and thus largely special cases. Other languages may use other formats and conventions in their implementations.
x86-64 (also called x86_64, x64, or amd64) is the 64-bit CPU architecture that is used in Intel and AMD processors. It is an extension to the 32-bit x86 (i386) architecture. The x86-64 architecture is used in most CPUs for home computers and servers in use today.
