-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
