To explain a bit more, the attacks_bb and attacks_bb function are instianted by the pos.attack_from and

pos.attack_from method respectively. The base code rely on conditional operation to exclude the calls leaving the

choice to the compiler to exclude it or not in its binary.

The specialized template versions of attack_bb and pos. attack_from don't create the above functions at all and

make the life easier for the compiler to make possibly better inlining decision.

Positive fishtest result and binary size change on my PC.

Base binary size: 558 Ko (572 095 octets)
New binary size: 557 Ko (570 553 octets)
