You may define this macro to do special handling for an alignment directive.
GAS will call it at the end of the assembly.

+An @code{.lcomm} directive with no explicit alignment parameter will use this
+macro to set @var{p2var} to the alignment that a request for @var{size} bytes
+will have. The alignment is expressed as a power of two. If no alignment
+should take place, the macro definition should do nothing. Some targets define
+a @code{.bss} directive that is also affected by this macro. The default
+definition will set @var{p2var} to the truncated power of two of sizes up to
+eight bytes.
