// Since Go only supports 32-bit and 64-bit floating point primitives,

// this number should be either 0, 4, or 8. 0 indicates no floating

// point registers for the ABI or that floating point values will be

// passed via the softfloat ABI.

// such as x87's 80-bit "registers" (not that we support x87 currently),

// use 8.
