By using objdump to determine where the = wrong source code is, I found out that the program stopped around the code = below.

UINT32
EFIAPI
MmioRead32 (
  IN     &= nbsp;UINTN  Address
  )
{
  UINT32   Value;  BOOLEAN  Flag;

  ASSERT ((Address & 3) =3D=3D = 0);

  Flag =3D FilterBeforeMmIoRead (FilterWidth32, Address, &a= mp;Value);
  if (Flag) {
    MemoryFence ();

&n= bsp;   if (IsTdxGuest ()) {
      Value =3D TdMmioRe= ad32 (Address);
    } else {
      Value =3D= *(volatile UINT32 *)Address;
    }

    Memor= yFence ();
  }

  FilterAfterMmIoRead (FilterWidth32, Ad= dress, &Value);

  return Value;
}

Output of objdu= mp:
