This directive, which is available for ELF targets, marks each symbol in
the comma-separated list of
names as a local symbol so that it
will not be externally visible. If the symbols do not already exist,
they will be created.
For targets where the
.lcomm directive (see
.lcomm symbol , length) does not
accept an alignment argument, which is the case for most ELF targets,
.local directive can be used in combination with
.comm symbol , length ) to define aligned local common data.
