bit.double_exact_xor

note: pad 2 is needed, but pad 8 is used for wflips-padding optimization and for smaller wflips.
dst1(bit_address) ^= src
dst2(bit_address) ^= src
dst1,dst2,src are bits.

Signature

def double_exact_xor dst1, dst2, src @ base_jump_label, cleanup { ... }

Defined in bit/logics.fj — lines 38–47 (view on GitHub).
