The unit test includes target-i386/cpu.c instead of simply linking against cpu.o because the test code will use static variables/functions from cpu.c.
Reasoning for each object file included in the test binary: * qom/cpu.o - for TYPE_CPU. Dependencies: * qom/qom-qobject.o * qom/qdev.o - for TYPE_DEVICE. Dependencies: * qom/container.o * vmstate.o. Dependencies: * qemu-file.o * hw/core/hotplug.o * hw/core/irq.o * hw/core/fw-path-provider.o * hw/core/qdev-properties.o * qom/object.o - for TYPE_OBJECT * x86_64-softmmu/target-i386/machine.o - for vmstate_x86_cpu * qemu-log.o - for the logging API, used by target-i386/cpu.c * libqemuutil.a - for QAPI visitors, error API, and other symbols * libqemustub.a - existing stubs, including: savevm, monitor symbols The remaining symbols used by target-i386/cpu.c were added as stubs to either tests/vl-stub.c and tests/x86-stub.c. Note: I couldn't add dependencies that ensure the target-specific object files are compiled on demand when building the test binary, but "make check" already requires "make" to be run first because of the qtest test cases, so I assume this is OK.
