Subject: [PATCH v2] ARM: VExpress: Makefile: add armv7 flags for inline assmembly code compiling
Date: Fri, 23 Aug 2013 16:02:40 +0800 [thread overview]
Message-ID: <52171720.4050501@asianux.com> (raw)
In-Reply-To: <52170C15.5010907@asianux.com>
When vexpress kernel is compiled for v6, it still can support armv7
instructions (hardware still support), so need let compiler know about
it for related inline assembly code, or compiling will fail.
The related failure command:
arm-linux-gnueabi-gcc -Wp,-MD,arch/arm/mach-vexpress/.dcscb.o.d -nostdinc -isystem /usr/lib/gcc/arm-linux-gnueabi/4.7/include -I/root/linux-next/arch/arm/include -Iarch/arm/include/generated -Iinclude -I/root/linux-next/arch/arm/include/uapi -Iarch/arm/include/generated/uapi -I/root/linux-next/include/uapi -Iinclude/generated/uapi -include /root/linux-next/include/linux/kconfig.h -D__KERNEL__ -mlittle-endian -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -Werror-implicit-function-declaration -Wno-format-security -fno-delete-null-pointer-checks -Werror=implicit-int -Werror=strict-prototypes -Os -Wno-maybe-uninitialized -fno-dwarf2-cfi-asm -fno-omit-frame-pointer -mapcs -mno-sched-prolog -fstack-protector -mabi=aapcs-linux -mno-thumb-interwork -funwind-
