Function combine_fragment_values 

Source 
fn combine_fragment_values(
    left: Unsigned36Bit,
    right: Unsigned36Bit,
) -> Unsigned36Bit
Expand description

Combine the fragments of an instruction into a final Unsigned36bit value.

Section 6-2.7 of the Users Handbook says:

The 36 bit address syllable is united with (inclusive OR) with the others (configuration, operation, index). Extra syllables of the latter group are also united into the word. The one bit syllables are set last, “not hold” being the last one.

So, the operation is definitely an OR-operation.

The Users Handbook says in section 6-2.3 “RULES FOR SYMEX FORMATION” Rule 5,

“A TYPE” is equivalent to “377604 + TYPE”

While this seems to contradict section 6-2.7, I think we should assume section 6-2.7 takes precedence.
