Many different tools around llvm do this for similar reasons.


So, I think we could do something like:

  --- !ifo-elf-v1
  Arch: X86_64
  Endian: little
  Sections:
    - Name:            .text
      Type:            SHT_PROGBITS
      Flags:           [ SHF_ALLOC, SHF_EXECINSTR ]
    - Name:            .data
      Type:            SHT_PROGBITS
      Flags:           [ SHF_WRITE, SHF_ALLOC ]
  Symbols:
    - Name:            _dataA
      Type:            Object
      Section:         .data
      Alignment: 32
    - Name:            __ZN3qux3barEii
      Type:            Function
      Section:         .text
      Weak: true
  ...

Notice the "ifo" and not the "ifso"; I think that could be a good way to denote that this is the unmerged format.

I could also drop the section parts:

  --- !ifo-elf-v1
  Arch: X86_64
  Endian: little
  Symbols:
    - Name:            _dataA
      Type:            Object
      Alignment: 32
    - Name:            __ZN3qux3barEii
      Type:            Function
      Weak: true
  ...

as soon as we discuss the section flags.
