-- These tests comprese three parts:
--   1. Sanity checks and other three-operand tests (especially those
--      where the fused operation makes a difference)
--   2. Multiply tests (third operand is neutral zero [0E+emax])
--   3. Addition tests (first operand is 1)
-- The multiply and addition tests are extensive because FMA may have
-- its own dedicated multiplication or addition routine(s), and they
-- also inherently check the left-to-right properties.

-- Sanity checks
