Enforcing aligned data
----------------------

   SPARC GAS normally permits data to be misaligned.  For example, it
permits the `.long' pseudo-op to be used on a byte boundary.  However,
the native SunOS and Solaris assemblers issue an error when they see
misaligned data.

   You can use the `--enforce-aligned-data' option to make SPARC GAS
also issue an error about misaligned data, just as the SunOS and Solaris
assemblers do.

   The `--enforce-aligned-data' option is not the default because gcc
issues misaligned data pseudo-ops when it initializes certain packed
data structures (structures defined using the `packed' attribute).  You
may have to assemble with GAS in order to initialize packed data
structures in your own code.
