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

Hello,

$ objdump -h # displays info about all below sections….
Sections:
Idx Name          Size      VMA               LMA               File off  Algn

While,
$ llvm-objdump -h # only displays subset of info…
Sections:
Idx Name          Size      Address          Type

Using ‘--show-lma' could get VMA and LMA details.

Can you suggest options to print ‘File off’ and ‘Alng’ with llvm-objdump?

Thank you in advance.
