…ion (#1656) This extension adds conversion instruction from float to tensor float (TF32) data format. TF32 uses 1 bit for a sign, 8 bits for an exponent and 10 bits for a fraction. This extension doesn’t introduce TF32 type in SPIR-V, instead instruction below uses 32-bit float type to represent TF32 value.
