<p>
When using the compiler and assembler's
<code>-dynlink</code> or <code>-shared</code> modes,
any load or store of a fixed memory location such as a global variable
must be assumed to overwrite <code>CX</code>.
Therefore, to be safe for use with these modes,
assembly sources should typically avoid CX except between memory references.

In C, a function argument written as a fixed size array
actually requires a pointer to the first element of the array.
C compilers are aware of this calling convention and adjust
the call accordingly, but Go cannot. In Go, you must pass
