[PATCH] D157269: [Clang][AArch64] Diagnostics for SME attributes when target doesn't have 'sme'

[Aaron Ballman via Phabricator via cfe-commits]

aaron.ballman added inline comments.


================
Comment at: clang/test/Sema/aarch64-sme-func-attrs-without-target-feature.cpp:20
+
+// No code is generated for declarations, so it should be fine to declare using the attribute.
+void streaming_compatible_decl() __arm_streaming_compatible; // OK
----------------
Is this a requirement of the specification? I guess I was surprised we're going to these lengths rather than diagnosing the attribute in SemaDeclAttr.cpp when sme is not enabled.
