speculable  exu stream  exu block  compute phase   operation   in the decimal floating point value domain   that produces condition codes and rounds toward negative infinity

native on: none

Decimal floating point subtraction in current rounding to nearest.

subdn(d x, d y) → d r0

operands: like Addd [dd:d]
