[Aaron Ballman via Phabricator via cfe-commits]

aaron.ballman added inline comments.


================
Comment at: clang/include/clang/Basic/DiagnosticSemaKinds.td:3255-3256
+def warn_not_xl_compatible
+    : Warning<"requested alignment of arguments 16 bytes or greater is not"
+              " compatible with previous versions of the AIX XL compiler">,
+      InGroup<DiagGroup<"builtin-assume-aligned-alignment">>;
----------------
Should we be talking about the AIX XL compiler in a Clang diagnostic?


================
Comment at: clang/lib/Sema/SemaDeclAttr.cpp:3957
 
+  if (Context.getTargetInfo().getTriple().isOSAIX() && (AlignVal >= 16))
+    Diag(AttrLoc, diag::warn_not_xl_compatible) << E->getSourceRange();
