From ebd1d3b74f8542a8f3bb80b453692d6d18f84071 Mon Sep 17 00:00:00 2001 From: Mathieu Malaterre Date: Wed, 5 Dec 2018 18:53:55 +0100 Subject: powerpc/32: Move the old 6xx -mcpu logic before the TARGET_CPU logic The code: ifdef CONFIG_6xx KBUILD_CFLAGS += -mcpu=powerpc endif was added in 2006 in commit f48b8296b315 ("[PATCH] powerpc32: Set cpu explicitly in kernel compiles"). This change was acceptable since the TARGET_CPU logic was 64-bit only. Since commit 0e00a8c9fd92 ("powerpc: Allow CPU selection also on PPC32") this logic is no longer acceptable after the TARGET_CPU specific. It currently appends -mcpu=powerpc at the end of the command line, after any TARGET_CPU specific: gcc -Wp,-MD,init/.do_mounts.o.d ... -mcpu=powerpc -mbig-endian -m32 ... -mcpu=e300c2 ... -mcpu=powerpc ... ../init/do_mounts.c Fixes: 0e00a8c9fd92 ("powerpc: Allow CPU selection also on PPC32") Signed-off-by: Mathieu Malaterre Signed-off-by: Michael Ellerman --- arch/powerpc/Makefile | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'arch/powerpc/Makefile') diff --git a/arch/powerpc/Makefile b/arch/powerpc/Makefile index 40bbeeeb5b4a..4b16588c920f 100644 --- a/arch/powerpc/Makefile +++ b/arch/powerpc/Makefile @@ -30,6 +30,10 @@ endif endif endif +ifdef CONFIG_PPC_BOOK3S_32 +KBUILD_CFLAGS += -mcpu=powerpc +endif + ifeq ($(CROSS_COMPILE),) KBUILD_DEFCONFIG := $(shell uname -m)_defconfig else @@ -241,10 +245,6 @@ KBUILD_CFLAGS += $(call cc-option,-fno-dwarf2-cfi-asm) # often slow when they are implemented at all KBUILD_CFLAGS += $(call cc-option,-mno-string) -ifdef CONFIG_PPC_BOOK3S_32 -KBUILD_CFLAGS += -mcpu=powerpc -endif - cpu-as-$(CONFIG_4xx) += -Wa,-m405 cpu-as-$(CONFIG_ALTIVEC) += $(call as-option,-Wa$(comma)-maltivec) cpu-as-$(CONFIG_E200) += -Wa,-me200 -- cgit v1.2.3
