[llvm-dev] llvm-objdump print file offset

[James Henderson via llvm-dev]

Hi,

This looks like a bug in llvm-objdump's output (I'd expect it to match
GNU's). There are no options to print the other columns. Could you file a
bug against llvm-objdump at https://bugs.llvm.org/, please?

You could also use llvm-readelf to get equivalent output. For a simple
object, it might look something like this:

C:\Work\TOOLCHAIN-5886> \llvm\build\Debug\bin\llvm-readelf.exe -S
C:\Work\TempWork\bar.o
There are 12 section headers, starting at offset 0x208:

Section Headers:
  [Nr] Name              Type            Address          Off    Size   ES
Flg Lk Inf Al
  [ 0]                   NULL            0000000000000000 000000 000000 00
     0   0  0
  [ 1] .strtab           STRTAB          0000000000000000 000198 000070 00
     0   0  1
 ...

It produces GNU readelf-style output, but this won't show you LMA output
(and there is no option to do so I'm afraid).

Hope that helps,

James
