The value of CF is different. +Steps to reproduce: +1. Compile this code +``` +void main() { + asm("blsi rax, rbx"); +} +``` +2. Execute and compare the result with the CPU. The value of `CF` is exactly the opposite. This problem happens with BLSR, too. +Additional information: +This bug is discovered by research conducted by KAIST SoftSec. |
