Hello all,
I want to see the assemble code of Xen. So I use make world and make
install to generate xen-4.1.2.gz. and unzip it to be the ELF file
xen-4.1.2. Then I use objdump tool to see the assemble code.
I found xen has only one section .text. Then I wonder where is the
section .data?
# objdump -h /boot/xen-4.1.2
/boot/xen-4.1.2: file format elf32-i386
Sections:
Idx Name Size VMA LMA File off Algn
0 .text 0013d41c 00100000 00100000 00000080 2**6
CONTENTS, ALLOC, LOAD, CODE
Another question: how do I know which assemble code in the ELF file
corresponds to the source code line "dom0->is_privileged=1" in
xen\arch\x86\setup.c file? In other words, how could I show the
function name in the assemble code file? by adding -g option when
making xen?

You should use the xen...-syms file instead. Either from the build tree or possibly from /boot if it is installed.> # objdump -h /boot/xen-4.1.2 > > /boot/xen-4.1.2: file format elf32-i386 > > Sections: > Idx Name Size VMA LMA File off Algn > 0 .text 0013d41c 00100000 00100000 00000080 2**6 > CONTENTS, ALLOC, LOAD, CODE > > Another question: how do I know which assemble code in the ELF file > corresponds to the source code line "dom0->is_privileged=1" in > xen\arch\x86\setup.c file?
