The <code>GLOBL</code> directive declares a symbol to be global.
The arguments are optional flags and the size of the data being declared as a global,
which will have initial value all zeros unless a <code>DATA</code> directive
has initialized it.
The <code>GLOBL</code> directive must follow any corresponding <code>DATA</code> directives.
