Hi,

in which case(s) do you have to set a comma or not?

586:KBUILD_CFLAGS += $(call cc-option,-fno-reorder-blocks,) \

...versus...

597:KBUILD_CFLAGS += $(call cc-option, -fno-stack-protector)

[ Makefile (next-20130704) ]

$ grep -nr KBUILD_CFLAGS Makefile | grep "call cc-option"
586:KBUILD_CFLAGS += $(call cc-option,-fno-reorder-blocks,) \
592:KBUILD_CFLAGS += $(call cc-option,-Wframe-larger-than=${CONFIG_FRAME_WARN})
597:KBUILD_CFLAGS += $(call cc-option, -fno-stack-protector)
623:KBUILD_CFLAGS       += $(call cc-option, -femit-struct-debug-baseonly) \
643:KBUILD_CFLAGS += $(call cc-option, -fno-inline-functions-called-once)
651:KBUILD_CFLAGS += $(call cc-option,-Wdeclaration-after-statement,)
657:KBUILD_CFLAGS       += $(call cc-option,-fno-strict-overflow)
660:KBUILD_CFLAGS   += $(call cc-option,-fconserve-stack)

Thanks in advance.

P.S.: Noticed while fighting through the LLVMLinux x86_64 (arch) patches.
