about the kernel compiling

Hi,
I don't know if there is any one interesting
in compiling the linux kernel. I have one question. As I know, compiler always put some informatin(known as header) into the obj file and
executable file. Does the kernel have this kind of header? If no, Is there any option for gcc to do it? thx!

Hi - You are probably talking about the frame pointer.
Typical options for kernel modules are:
-Wall
-Wstrict-prototypes
-Wno-trigraphs
-O2
-fomit-frame-pointer
-fno-strict-aliasing
-fno-common
-Wno-unused
-pipe
-fpreferred-stack-boundary=2
-march=i686
You can find explanations of gcc's command line options:
