mips_fp_le-objdump -S will show different result if the $pwd is different

[Johnson_Hac@alphanetworks.com]

Hi folks :
I am using the mips_fp_le-gcc to compile my linux kernel
and I can use mips_fp_le-objdump -S the init/main.o and I see the source
code inter mixed with the assembly code , but but if I change to another
directory
like /home/johnson and use mips_fp_le-objdump -S linux-2.4.x/init/main.o
I will see no source code mixed ,why ?
my binutils is 2.12.1
I try to use the normal gcc tool chain , not crosscompile one ,and it's
fine to
work
Thanks for your help
