+x86 BLSI and BLSR semantic bug
+Description of problem
+The result of instruction BLSI and BLSR is different from the CPU. The value of CF is different.
+
+Steps to reproduce
+
+Compile this code
+
+
+void main() {
+    asm("blsi rax, rbx");
+}
+
+
+
+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.
