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

UINT= 32
EFIAPI
MmioRead32 (
=C2=A0 IN =C2=A0 =C2=A0 =C2=A0UINTN =C2=A0A= ddress
=C2=A0 )
{
=C2=A0 UINT32 =C2=A0 Value;
=C2=A0 BOOLEAN = =C2=A0Flag;

=C2=A0 ASSERT ((Address & 3) =3D=3D 0);

=C2= =A0 Flag =3D FilterBeforeMmIoRead (FilterWidth32, Address, &Value);
= =C2=A0 if (Flag) {
=C2=A0 =C2=A0 MemoryFence ();

=C2=A0 =C2=A0 if= (IsTdxGuest ()) {
=C2=A0 =C2=A0 =C2=A0 Value =3D TdMmioRead32 (Address)= ;
=C2=A0 =C2=A0 } else {
=C2=A0 =C2=A0 =C2=A0 Value =3D *(volatile UI= NT32 *)Address;

=C2=A0 =C2=A0 MemoryFence ();

=C2=A0 FilterAfterMmIoRead (FilterWidth32, Address, &Va= lue);

=C2=A0 return Value;
