+x86 BEXTR semantic bug
+Description of problem:
+The result of instruction BEXTR is different with from the CPU. The value of destination register is different. I think QEMU does not consider the operand size limit.
+Steps to reproduce:
+1. Compile this code
+```
+void main() {
+    asm("mov rax, 0x17b3693f77fb6e9");
+    asm("mov rbx, 0x8f635a775ad3b9b4");
+    asm("mov rcx, 0xb717b75da9983018");
+    asm("bextr eax, ebx, ecx");
+}
+```
+2. Execute and compare the result with the CPU.
+    - CPU
+        - RAX = 0x5a
+    - QEMU
+        - RAX = 0x635a775a
+Additional information:
+This bug is discovered by research conducted by KAIST SoftSec.
