The problem is that arrays are reference types, so you can modify the original data. Share Follow WebJan 15, 2009 · It's straightforward, except for one part. In his reverse function, Igor does the following: // Reverses bits in a byte static byte Reverse ( byte b) { int rev = (b >> 4) ( (b & 0xf) << 4); rev = ( (rev & 0xcc) >> 2) ( (rev & 0×33) << 2); rev = ( (rev & 0xaa) >> 1) ( (rev & 0×55) << 1); return ( byte )rev; }

WebNov 22, 2010 · avx2 register bits reverse shows how to do this for a packed vector of 32-bit elements. The same code ported to 128-bit vectors would compile just fine with AVX. It's still good for a single 32-bit int because x86 has very efficient round-trip between integer and vector regs: int bitrev = _mm_cvtsi128_si32 ( rbit32( _mm_cvtsi32_si128(input) ) );.

Setting the n th bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n); Bit n will be set if x is 1, and cleared if x is 0. If x has some other value, you get garbage. x = !!x will booleanize it to 0 or 1.
