@subsection NEON Alignment Specifiers
@cindex alignment for NEON instructions
Some NEON load/store instructions allow an optional address
alignment qualifier.
The ARM documentation specifies that this is indicated by
@samp{@@ @var{align}}. However GAS already interprets
the @samp{@@} character as a "line comment" start,
so @samp{: @var{align}} is used instead. For example:
@smallexample
vld1.8 @{q0@}, [r0, :128]
@end smallexample
