================
Comment at: clang/lib/AST/RecordLayoutBuilder.cpp:1781
-  // pragma align(packed).
-  if (isAIXLayout(Context) && !MaxFieldAlignment.isZero() && !FieldSize)
-    FieldAlign = std::min(FieldAlign, MaxFieldAlignmentInBits);

Sorry Steven, not sure what you are asking for. 

attribute packed will set 'FieldPacked` to true, in which case we ignore the 
max field alignment  (and why the new comment says, or 1 if packed). IIUC the 
MaXFieldAlign is set by only by pragma pack and pragma align in the Itanium 
recored layout builder, and the place where it is set based on attribute packed 
is int he Microsoft record layout builder and doesn't affect us here.
