I wrote "git log" to tell you to read the changelog entries which document that we went from EXTRA_CFLAGS to ccflags-y etc. > after grepping through the source tree, > i'm still confused. as a simple example, consider the possible > variables for assembler flags. so far, i've found occurrences of: > > * AFLAGS > * EXTRA_AFLAGS > * ASFLAGS > * AFLAGS-y > * KBUILD_AFLAGS > * aflags-y > * asflags-y > * extra-aflags-y You need to open the files and look into their usage of the above variables. The above list is almost only local variables that has no specific interpretation / functionality in kbuild. Samples: extra-aflags-y Only referenced in arch/ppc/boot/simple/Makefile and never assigned. Something to be cleaned up. afalgs-y Used as a local temporary variable in arch/m32r/Makefile arch/s390/Makefile The new asflags-y should be introduced to clean it up but not a bug AFLAGS-y Used as local variable in arch/powerpc/Makefile asfalgs-y should be introduced to clean it up but not a bug. So see - with a bit of careful investigation things are much less confusing.
