Subject: Relinking zImage when nothing changes
Date: Fri, 12 Aug 2011 10:46:24 -0700 [thread overview]
Message-ID: <4E4566F0.4020001@codeaurora.org> (raw)
I was hoping with the recent patch e78e8f2 (kernel: prevent unnecessary
rebuilding due to config_data.gz, 2011-07-05) compiling ARM linux a
second time would amount to no more linking. This doesn't seem to be the
case though. Doing a make V=2 I see that lib1funcs.S is shipped and thus
we have to recompile it although nothing actually changed. This in turn
requires us to relink the compressed vmlinux and then recreate the zImage.
Kernel: arch/arm/boot/Image is ready
SHIPPED arch/arm/boot/compressed/lib1funcs.S - due to missing .cmd file
AS arch/arm/boot/compressed/lib1funcs.o - due to: arch/arm/boot/compressed/lib1funcs.S
LD arch/arm/boot/compressed/vmlinux - due to: arch/arm/boot/compressed/lib1funcs.o
OBJCOPY arch/arm/boot/zImage - due to: arch/arm/boot/compressed/vmlinux
Kernel: arch/arm/boot/zImage is ready
Is there any way to avoid this? Perhaps the shipped command could become
a bit wiser?
