            Bug ID: 57969
           Summary: AIX data alignment behaviour
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gseanmcg at gmail dot com
            Target: powerpc-ibm-aix

Using gcc 4.8.1 on AIX, should a 32-byte static data alignment declaration such
as the following work as intended by the author?

  static float __attribute__((aligned(32))) data_with_32byte_alignment[512];

I know that Altivec only requires 16-byte alignment, and I'm not certain if
this is a bug, as I've also seen some documentation online suggesting it could
an ABI limitation on AIX. Perhaps someone can correct me and send me on my way
if this is the case.
