When disassembled, the function at 401b0c has a section where the following instruction sequence is used.At address: 401c77 movaps xmm0,xmm4 addpd xmm0,xmm3 subpd xmm0,xmm4 subpd xmm3,xmm0In this sequence, xmm3 is always zero.Based on a similar sequence, several other registers are eventually zeroed as well. This undermines the logic in the entire routine.Could you please verify this against the source code ?
