I'm working on a Linux kernel module for a 2.6.x kernel and I need to view the assembly output, though it's currently being done as a temporary file an deleted afterwords. I'd like to have the assembly output mixed with my C source file so I can easily trace where my problem lies. This is for an ARMv6 core and apparently objdump doesn't support this architecture. I've included my makefile below.

ETREP=/xxSourceTreexx/
GNU_BIN=$(ETREP)/arm-none-linux-gnueabi/bin
CROSS_COMPILE := $(GNU_BIN)/arm-none-linux-gnueabi-
ARCH := arm
KDIR=$(ETREP)/linux-2.6.31/
MAKE= CROSS_COMPILE=$(CROSS_COMPILE) ARCH=$(ARCH) make
obj-m += xxfile1xx.o

all:
 $(MAKE) -C $(KDIR) M=$(PWD) modules

clean:
 $(MAKE) -C $(KDIR) M=$(PWD) clean
