[PATCH] D109387: [NFC][AIX] Check for typedef properly when getting preferred type align

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

Oh, no, I don't think this is NFC.  It seems very likely that there's some case where the behavior is distinguishable.  Maybe a typedef of a record with an alignment attribute?

  __attribute__((aligned(2), packed)) struct float4 { float x, y, z, w; };
  typedef struct float4 float4typedef;
  
  struct {
    float4typedef field; // presumably still eligible for alignment upgrade
  };
