### 7.40 `.ident`

This directive is used by some assemblers to place tags in object files. The behavior of this directive varies depending on the target. When using the a.out object file format, `as` simply accepts the directive for source-file compatibility with existing assemblers, but does not emit anything for it. When using COFF, comments are emitted to the `.comment` or `.rdata` section, depending on the target. When using ELF, comments are emitted to the `.comment` section.
