Macros¶

bit.pointers.ptr_init — Initializes the global opcodes and pointer-copies required for the pointers macros.
bit.pointers.set_jump_pointer — Sets both to_jump and to_jump_var to point to the given pointer.
bit.pointers.set_flip_pointer — Sets both to_flip and to_flip_var to point to the given pointer.
bit.pointers.advance_by_one_and_flip__ptr_wflip — Advances *to_flip by 1 (which takes n flips, from bit0 to bit1, bit2,…).

bit.ptr_jump — Jump to the address stored in ptr. Effectively ;*ptr.
bit.ptr_flip — Flip the bit whose address is stored in ptr. Effectively *ptr;.
bit.ptr_flip_dbit — Effectively: (*ptr)+dbit;
bit.xor_to_ptr — Effectively: bit.xor *ptr, bit
bit.ptr_wflip — Effectively: wflip *ptr, value
bit.ptr_wflip_2nd_word — Effectively: wflip (*ptr)+w, value
bit.xor_from_ptr — Effectively: bit.xor dst, *ptr
bit.exact_xor_from_ptr — Effectively: bit.exact_xor dst, *ptr
bit.ptr_inc — ptr += 2w — advance a w-wide bit-pointer by one dw-aligned word.
bit.ptr_dec — ptr[:n] -= 2w
