+@cindex @code{local} directive
+This directive, which is available for ELF targets, marks each symbol in
+the comma-separated list of @code{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 @code{.lcomm} directive (@pxref{Lcomm}) does not
+accept an alignment argument, which is the case for most ELF targets,
+the @code{.local} directive can be used in combination with @code{.comm}
+(@pxref{Comm}) to define aligned local common data.
