Fastest way to expand bits in a field to all (overlapping + adjacent) set bits in a mask?

Asked 2019-Jun-07 at 12:26

Say I have 2 binary inputs named IN and MASK. Actual field size could be 32 to 256 bits depending on what instruction set is used to accomplish the task. Both inputs change every call.

The following approach needs only a single loop, with the number of iterations equal to the number of 'groups' found. I don't know if it will be more efficient than your approach; there's 6 arith/bitwise operations in each iteration.

In pseudo code (C-like):

Why does a program created by a Brainfuck into assembly compiler crash?

Consider the following Brainfuck code:

Nothing's going on - the instructions are identical. In particular, jne and jnz are just aliases for the same instruction. (And byte ptr is just extra verbosity for what could in this case be inferred just from the size of the register operand)

NASM assembled it correctly, pwndbg disassembled it correctly, ...and your compiler has some bug lurking somewhere. :)
