It could be solved with an 'override' directive on CFLAGS, but that would actually prevent setting different CFLAGS manually. Instead, filter the CFLAGS argument from the top-level Makefile (so you could still call make with a different CFLAGS argument on a rom/Makefile manually) Signed-off-by: Marc-Andr=C3=A9 Lureau --- Makefile | 3 ++- pc-bios/optionrom/Makefile | 2 -- 2 files changed, 2 insertions(+), 3 deletions(-) diff --git a/Makefile b/Makefile index 0d7647f..50b4b3a 100644 --- a/Makefile +++ b/Makefile @@ -225,8 +225,9 @@ dtc/%: $(SUBDIR_RULES): libqemuutil.a libqemustub.a $(common-obj-y) $(qom-obj-y= ) $(crypto-aes-obj-$(CONFIG_USER_ONLY)) =20 ROMSUBDIR_RULES=3D$(patsubst %,romsubdir-%, $(ROMS)) +# Only keep -O and -g cflags romsubdir-%: - $(call quiet-command,$(MAKE) $(SUBDIR_MAKEFLAGS) -C pc-bios/$* V=3D"$(V= )" TARGET_DIR=3D"$*/",) + $(call quiet-command,$(MAKE) $(SUBDIR_MAKEFLAGS) -C pc-bios/$* V=3D"$(V= )" TARGET_DIR=3D"$*/" CFLAGS=3D"$(filter -O% -g%,$(CFLAGS))",) =20 ALL_SUBDIRS=3D$(TARGET_DIRS) $(patsubst %,pc-bios/%, $(ROMS)) =20 diff --git a/pc-bios/optionrom/Makefile b/pc-bios/optionrom/Makefile index 24e175e..6bab490 100644 --- a/pc-bios/optionrom/Makefile +++ b/pc-bios/optionrom/Makefile @@ -24,8 +24,6 @@ QEMU_CFLAGS +=3D $(call cc-option, $(QEMU_CFLAGS), -no-= integrated-as) QEMU_CFLAGS +=3D -m32 -include $(SRC_PATH)/pc-bios/optionrom/code16gcc.h endif =20 -# Drop gcov and glib flags -CFLAGS :=3D $(filter -O% -g%, $(CFLAGS)) QEMU_INCLUDES +=3D -I$(SRC_PATH) =20 Wa =3D -Wa, --=20 2.9.0
