as: Ident
7.43 '.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.
