x86 BLSMSK semantic bug
description = """The result of instruction BLSMSK is different with from the CPU. The value of CF is different."""
reproduce = """1. Compile this code
void main() {
    asm("mov rax, 0x65b2e276ad27c67");
    asm("mov rbx, 0x62f34955226b2b5d");

2. Execute and compare the result with the CPU.

        - CF = 0
    - QEMU
        - CF = 1"""
