Seems to me this should be a separate change or at least motivated in the commit text. > -CFLAGS += $(autodepend-flags) -g -fomit-frame-pointer -Wall I like removing the redundant -g but wouldn't it be cleaner to set the CFLAGS to an empty string in the beginning of the file and then have a seprate line for -g where all the CFLAGS are set? > +CFLAGS += $(autodepend-flags) -Wall > +CFLAGS += $(call cc-option, -fomit-frame-pointer, "") > CFLAGS += $(call cc-option, -fno-stack-protector, "") > CFLAGS += $(call cc-option, -fno-stack-protector-all, "") > CFLAGS += -I. > @@ -51,4 +51,4 @@ install: > install $(tests_and_config) $(DESTDIR) > > clean: arch_clean > - $(RM) *.o *.a .*.d $(libcflat) $(cflatobjs) > + $(RM) *.o *.a .*.d lib/.*.d $(libcflat) $(cflatobjs) > diff --git a/config-x86-common.mak b/config-x86-common.mak > index bf88c672de472..7e481192a0737 100644 > --- a/config-x86-common.mak > +++ b/config-x86-common.mak > @@ -1,13 +1,9 @@ > #This is a make file with common rules for both x86 & x86-64 > > -CFLAGS += -I../include/x86 > - > all: test_cases > > -cflatobjs += \ > - lib/x86/io.o \ > - lib/x86/smp.o > - > +cflatobjs += lib/x86/io.o > +cflatobjs += lib/x86/smp.o > cflatobjs += lib/x86/vm.o > cflatobjs += lib/x86/fwcfg.o > cflatobjs += lib/x86/apic.o > @@ -20,15 +16,17 @@ $(libcflat): LDFLAGS += -nostdlib > $(libcflat): CFLAGS += -ffreestanding -I lib > > CFLAGS += -m$(bits) > +CFLAGS += -O1 > > libgcc := $(shell $(CC) -m$(bits) --print-libgcc-file-name) > > FLATLIBS = lib/libcflat.a $(libgcc) > %.elf: %.o $(FLATLIBS) flat.lds > - $(CC) $(CFLAGS) -nostdlib -o $@ -Wl,-T,flat.lds $(filter %.o, $^) $(FLATLIBS) > + $(CC) $(CFLAGS) -nostdlib -o $@ -Wl,-T,flat.lds \ > + $(filter %.o, $^) $(FLATLIBS) > > %.flat: %.elf > - objcopy -O elf32-i386 $^ $@ > + $(OBJCOPY) -O elf32-i386 $^ $@ > > tests-common = $(TEST_DIR)/vmexit.flat $(TEST_DIR)/tsc.flat \ > $(TEST_DIR)/smptest.flat $(TEST_DIR)/port80.flat \ > @@ -105,7 +103,7 @@ $(TEST_DIR)/vmx.elf: $(cstart.o) $(TEST_DIR)/vmx.o $(TEST_DIR)/vmx_tests.o > > arch_clean: > $(RM) $(TEST_DIR)/*.o $(TEST_DIR)/*.flat $(TEST_DIR)/*.elf \ > - $(TEST_DIR)/.*.d $(TEST_DIR)/lib/.*.d $(TEST_DIR)/lib/*.o > + $(TEST_DIR)/.*.d lib/x86/.*.d > > api/%.o: CFLAGS += -m32 > > diff --git a/run_tests.sh b/run_tests.sh > index 55ecac5bed3a4..f373c533b75b2 100755 > --- a/run_tests.sh > +++ b/run_tests.sh > @@ -27,7 +27,7 @@ function run() > return > fi > > - cmdline="./x86-run $kernel -smp $smp -display none $opts" > + cmdline="./x86-run $kernel -smp $smp $opts" > if [ $verbose != 0 ]; then > echo $cmdline > fi > -- > 1.8.1.4 > > _______________________________________________ > kvmarm mailing list > kvmarm@xxxxxxxxxxxxxxxxxxxxx > https://lists.cs.columbia.edu/cucslists/listinfo/kvmarm -- Christoffer -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
