[llvm-objdump] Fails to disassemble file when debug content is present

[jcdutton]

This outputs the disassembly:
llvm-objdump -d crc8-nodebug.ko
This fails to output a disassembly:
llvm-objdump -d crc8-debug.ko

[jcdutton]

crc8-debug.ko.zip
crc8-nodebug.ko.zip

Note: I zipped the files as the attachment would not accept .ko files.
These are Linux kernel module files from the openwrt project.

They should both output disassembly.
Also note, other tools also have a similar problem: objdump, and aarch64-linux-gnu-objdump

[jcdutton]

It turns out the debug file do not include the .text sections, so objdump is treating them as .bss sections.
It turns out the debug files do not include the .text content, so the debug and nodebug file need to be merged in order for objdump to work. It would be nice if objdump had an option to load both files in order to disassemble with line numbers etc.
