+x86 BZHI semantic bug
+Description of problem
+The result of instruction BZHI is different from the CPU. The value of destination register and SF of EFLAGS are different.
+
+Steps to reproduce
+
+Compile this code
+
+
+void main() {
+    asm("mov rax, 0xb1aa9da2fe33fe3");
+    asm("mov rbx, 0x80000000ffffffff");
+    asm("mov rcx, 0xf3fce8829b99a5c6");
+    asm("bzhi rax, rbx, rcx");
+}
+
+
+
+Execute and compare the result with the CPU.
+
+CPU
+
+RAX = 0x0x80000000ffffffff
+SF = 1
+
+
+QEMU
+
+RAX = 0xffffffff
+SF = 0
+
+
+

+
+
+Additional information
+This bug is discovered by research conducted by KAIST SoftSec.
