constant. It can do this by reading object files. If cgo has decided
that t1 is a type, v2 and v3 are variables or functions, and i4, i5
are integer constants, u6 is an unsigned integer constant, and f7 and f8
are float constants, and s9 and s10 are string constants, it generates:

If a vector instruction takes a length or an index as an argument then it will be the
first argument.
For example, <code>VLEIF</code> <code>$1,</code> <code>$16,</code> <code>V2</code> will load
the value sixteen into index one of <code>V2</code>.
Care should be taken when using vector instructions to ensure that they are available at
runtime.
To use vector instructions a machine must have both the vector facility (bit 129 in the
