+x86 ADOX and ADCX semantic bug
+Description of problem
+The result of instruction ADOX and ADCX are different from the CPU. The value of one of EFLAGS is different.
+
+Steps to reproduce
+
+Compile this code
+
+
+void main() {
+    asm("push 512; popfq;");
+    asm("mov rax, 0xffffffff84fdbf24");
+    asm("mov rbx, 0xb197d26043bec15d");
+    asm("adox eax, ebx");
+}
+
+
+
+Execute and compare the result with the CPU. This problem happens with ADCX, too (with CF).
