-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
-
-Compile this code
-
-void main() {
-    asm("mov rax, 0x17b3693f77fb6e9");
-    asm("mov rbx, 0x8f635a775ad3b9b4");
-    asm("mov rcx, 0xb717b75da9983018");
-    asm("bextr eax, ebx, ecx");
-}
-
-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.
