llvm-for-llvmta/test/tools/yaml2obj/ELF/symtab-implicit-sections-size-content.yaml

## For implicit symbol table sections, `Size` and/or `Content` fields can also
## be specified in YAML. Here we test the behavior in different cases.

## When no `Size` or `Content` is specified for a symbol table section,
## yaml2obj writes the default content.
