speculable  exu stream  exu block  compute phase   operation   in the binary floating point value domain   that produces condition codes and rounds to nearest, ties toward even adjacent value

native on: Silver

Floating point subtraction in current rounding to even.

subfe(f x, f y) → f r0

operands: like Addf [ff:f]
