From: Catalin Marinas Date: Thu, 30 Jun 2005 16:04:14 +0000 (+0100) Subject: [PATCH] ARM: 2778/1: Add -mno-thumb-interwork to CFLAGS_ABI X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c28a814f25d48f193565003223df0ae617796892;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git [PATCH] ARM: 2778/1: Add -mno-thumb-interwork to CFLAGS_ABI Patch from Catalin Marinas The new EABI gcc adds -mthumb-interwork by default, even if -mabi=apcs-gnu is passed. This causes a warning for every compiled C file when -march=armv4 is used. The patch adds -mno-thumb-interwork if the option is supported. This is also useful since we don't need any ARM/Thumb interworking in the kernel Signed-off-by: Catalin Marinas Signed-off-by: Russell King --- diff --git a/arch/arm/Makefile b/arch/arm/Makefile index 8330495e2448..eb933dcafba0 100644 --- a/arch/arm/Makefile +++ b/arch/arm/Makefile @@ -56,7 +56,7 @@ tune-$(CONFIG_CPU_XSCALE) :=$(call cc-option,-mtune=xscale,-mtune=strongarm110) tune-$(CONFIG_CPU_V6) :=-mtune=strongarm # Need -Uarm for gcc < 3.x -CFLAGS_ABI :=$(call cc-option,-mapcs-32,-mabi=apcs-gnu) +CFLAGS_ABI :=$(call cc-option,-mapcs-32,-mabi=apcs-gnu) $(call cc-option,-mno-thumb-interwork,) CFLAGS +=$(CFLAGS_ABI) $(arch-y) $(tune-y) $(call cc-option,-mshort-load-bytes,$(call cc-option,-malignment-traps,)) -msoft-float -Uarm AFLAGS +=$(CFLAGS_ABI) $(arch-y) $(tune-y) -msoft-float
