主题: RELEASE build error with QEMU_PV_VARS

Hello,
I met undefined reference to `MmioWrite32' error when building AARCH64 with -D QEMU_PV_VARS=TRUE on RELEASE  mode,

build -n 128 -p ArmVirtPkg/ArmVirtQemu.dsc -a AARCH64 -b RELEASE  -D QEMU_PV_VARS=TRUE  -t GCC5

…
OvmfPkg/VirtMmCommunicationDxe/QemuMmio.c:159: undefined reference to `MmioWrite32'
OvmfPkg/VirtMmCommunicationDxe/QemuMmio.c:161: undefined reference to `MmioRead32'
….

It is built successfully without the option QEMU_PV_VARS, or build with DEBUG mode.
Not sure if I am missing anything?

Best Regards
Limin Wang.
