ARC kernels have historically been built with -O3, despite top level Makefile defaulting to -O2. This was facilitated by implicitly ordering of arch makefile include AFTER top level assigned -O2. An upstream fix to top level a1c48bb160f ("Makefile: Fix unrecognized cross-compiler command line options") changed the ordering, making ARC -O3 defunct. Fix that by NOT relying on any ordering whatsoever and use the proper arch override facility now present in kbuild (ARCH_*FLAGS) Depends-on: ("kbuild: Allow arch Makefiles to override {cpp,ld,c}flags") Suggested-by: Michal Marek Cc: Geert Uytterhoeven Signed-off-by: Vineet Gupta Signed-off-by: Greg Kroah-Hartman --- arch/arc/Makefile | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) --- a/arch/arc/Makefile +++ b/arch/arc/Makefile @@ -43,7 +43,8 @@ endif ifndef CONFIG_CC_OPTIMIZE_FOR_SIZE # Generic build system uses -O2, we want -O3 -cflags-y += -O3 +# Note: No need to add to cflags-y as that happens anyways +ARCH_CFLAGS += -O3 endif # small data is default for elf32 tool-chain.
