speculable  exu stream  exu block  compute phase   operation   in the binary floating point value domain  

native on: Silver Gold

Binary float reciprocal square root. i.e. the result is 1/√x.

This operation doesn't need rounding since no precision is lost.


rrootf(f x) → f r0

operands: like Addf [ff:f]
