So fix both by adjusting the rules: - remove $(SPLIT_TESTS_TARGETS) from the $(TEST_GEN_PROGS) rules, and rename it to $(SPLIT_TEST_GEN_PROGS) - fix $(SPLIT_TESTS_OBJS) so that it plays well with $(OUTPUT), rename it to $(SPLIT_TEST_GEN_OBJ), and list the object file explicitly in the $(SPLIT_TEST_GEN_PROGS) link rule Fixes: 17da79e009c3 ("KVM: arm64: selftests: Split get-reg-list test code", 2023-08-09) Signed-off-by: Paolo Bonzini Tested-by: Andrew Jones --- tools/testing/selftests/kvm/Makefile | 20 ++++++++++++-------- 1 file changed, 12 insertions(+), 8 deletions(-) diff --git a/tools/testing/selftests/kvm/Makefile b/tools/testing/selftests/kvm/Makefile index 52c59bad7213..2200f06b740b 100644 --- a/tools/testing/selftests/kvm/Makefile +++ b/tools/testing/selftests/kvm/Makefile @@ -251,32 +251,36 @@ LIBKVM_C_OBJ := $(patsubst %.c, $(OUTPUT)/%.o, $(LIBKVM_C)) LIBKVM_S_OBJ := $(patsubst %.S, $(OUTPUT)/%.o, $(LIBKVM_S)) LIBKVM_STRING_OBJ := $(patsubst %.c, $(OUTPUT)/%.o, $(LIBKVM_STRING)) LIBKVM_OBJS = $(LIBKVM_C_OBJ) $(LIBKVM_S_OBJ) $(LIBKVM_STRING_OBJ) -SPLIT_TESTS_TARGETS := $(patsubst %, $(OUTPUT)/%, $(SPLIT_TESTS)) -SPLIT_TESTS_OBJS := $(patsubst %, $(ARCH_DIR)/%.o, $(SPLIT_TESTS)) +SPLIT_TEST_GEN_PROGS := $(patsubst %, $(OUTPUT)/%, $(SPLIT_TESTS)) +SPLIT_TEST_GEN_OBJ := $(patsubst %, $(OUTPUT)/$(ARCH_DIR)/%.o, $(SPLIT_TESTS)) TEST_GEN_OBJ = $(patsubst %, %.o, $(TEST_GEN_PROGS)) TEST_GEN_OBJ += $(patsubst %, %.o, $(TEST_GEN_PROGS_EXTENDED)) TEST_DEP_FILES = $(patsubst %.o, %.d, $(TEST_GEN_OBJ)) TEST_DEP_FILES += $(patsubst %.o, %.d, $(LIBKVM_OBJS)) -TEST_DEP_FILES += $(patsubst %.o, %.d, $(SPLIT_TESTS_OBJS)) +TEST_DEP_FILES += $(patsubst %.o, %.d, $(SPLIT_TEST_GEN_OBJ)) -include $(TEST_DEP_FILES) -$(TEST_GEN_PROGS) $(TEST_GEN_PROGS_EXTENDED): %: %.o +x := $(shell mkdir -p $(sort $(OUTPUT)/$(ARCH_DIR) $(dir $(LIBKVM_C_OBJ) $(LIBKVM_S_OBJ)))) + +$(filter-out $(SPLIT_TEST_GEN_PROGS), $(TEST_GEN_PROGS)) \ +$(TEST_GEN_PROGS_EXTENDED): %: %.o $(CC) $(CFLAGS) $(CPPFLAGS) $(LDFLAGS) $(TARGET_ARCH) $< $(LIBKVM_OBJS) $(LDLIBS) -o $@ $(TEST_GEN_OBJ): $(OUTPUT)/%.o: %.c $(CC) $(CFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c $< -o $@ -$(SPLIT_TESTS_TARGETS): %: %.o $(SPLIT_TESTS_OBJS) +$(SPLIT_TEST_GEN_PROGS): $(OUTPUT)/%: $(OUTPUT)/%.o $(OUTPUT)/$(ARCH_DIR)/%.o $(CC) $(CFLAGS) $(CPPFLAGS) $(LDFLAGS) $(TARGET_ARCH) $^ $(LDLIBS) -o $@ +$(SPLIT_TEST_GEN_OBJ): $(OUTPUT)/$(ARCH_DIR)/%.o: $(ARCH_DIR)/%.c + $(CC) $(CFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c $< -o $@ EXTRA_CLEAN += $(GEN_HDRS) \ $(LIBKVM_OBJS) \ - $(SPLIT_TESTS_OBJS) \ + $(SPLIT_TEST_GEN_OBJ) \ $(TEST_DEP_FILES) \ $(TEST_GEN_OBJ) \ cscope.* -x := $(shell mkdir -p $(sort $(dir $(LIBKVM_C_OBJ) $(LIBKVM_S_OBJ)))) $(LIBKVM_C_OBJ): $(OUTPUT)/%.o: %.c $(GEN_HDRS) $(CC) $(CFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c $< -o $@ @@ -290,7 +294,7 @@ $(LIBKVM_STRING_OBJ): $(OUTPUT)/%.o: %.c $(CC) $(CFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c -ffreestanding $< -o $@ x := $(shell mkdir -p $(sort $(dir $(TEST_GEN_PROGS)))) -$(SPLIT_TESTS_OBJS): $(GEN_HDRS) +$(SPLIT_TEST_GEN_OBJ): $(GEN_HDRS) $(TEST_GEN_PROGS): $(LIBKVM_OBJS) $(TEST_GEN_PROGS_EXTENDED): $(LIBKVM_OBJS) $(TEST_GEN_OBJ): $(GEN_HDRS)
