(x86) Filter this option from the recently introduced handling of KCFLAGS vs EXTRA_OPTIMISATION Fixes: 1d42af720c6b ("kernel: use KCFLAGS for passing EXTRA_OPTIMIZATION flags") Suggested-by: Felix Fietkau Signed-off-by: Kevin Darbyshire-Bryant --- diff --git a/include/kernel.mk b/include/kernel.mk index d99dd0a534..001718d89d 100644 --- a/include/kernel.mk +++ b/include/kernel.mk @@ -101,7 +101,7 @@ endif KERNEL_MAKE = $(MAKE) $(KERNEL_MAKEOPTS) KERNEL_MAKE_FLAGS = \ - KCFLAGS="$(call iremap,$(BUILD_DIR),$(notdir $(BUILD_DIR))) $(call qstrip,$(CONFIG_EXTRA_OPTIMIZATION)) $(call qstrip,$(CONFIG_KERNEL_CFLAGS))" \ + KCFLAGS="$(call iremap,$(BUILD_DIR),$(notdir $(BUILD_DIR))) $(filter-out -fno-plt,$(call qstrip,$(CONFIG_EXTRA_OPTIMIZATION))) $(call qstrip,$(CONFIG_KERNEL_CFLAGS))" \ HOSTCFLAGS="$(HOST_CFLAGS) -Wall -Wmissing-prototypes -Wstrict-prototypes" \ CROSS_COMPILE="$(KERNEL_CROSS)" \ ARCH="$(LINUX_KARCH)" \ diff --git a/rules.mk b/rules.mk index 8d4f619211..8a4254e638 100644 --- a/rules.mk +++ b/rules.mk @@ -62,7 +62,6 @@ ARCH_PACKAGES:=$(call qstrip,$(CONFIG_TARGET_ARCH_PACKAGES)) BOARD:=$(call qstrip,$(CONFIG_TARGET_BOARD)) SUBTARGET:=$(call qstrip,$(CONFIG_TARGET_SUBTARGET)) TARGET_OPTIMIZATION:=$(call qstrip,$(CONFIG_TARGET_OPTIMIZATION)) -export EXTRA_OPTIMIZATION:=$(filter-out -fno-plt,$(call qstrip,$(CONFIG_EXTRA_OPTIMIZATION))) TARGET_SUFFIX=$(call qstrip,$(CONFIG_TARGET_SUFFIX)) BUILD_SUFFIX:=$(call qstrip,$(CONFIG_BUILD_SUFFIX)) SUBDIR:=$(patsubst $(TOPDIR)/%,%,${CURDIR})
