+-- 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.
