Hmm, the first one tests that LS64 is not on by default on `armv8.7a`, and the 
second tests that `armv8.7a+ls64` enables it. Why these are duplicates?

If you mean L276/277, I guess the intent is to test both syntaxes that we 
support


================
Comment at: clang/test/Driver/aarch64-ras.c:14
+// RAS is on by default for v8.2a, but can be disabled by +noras
+// FIXME: in the current implementation, RAS is not on by default at all for 
v8.2a (the test says it all...)
+// RUN: %clang -target aarch64 -march=armv8.2a  -### -c %s 2>&1 | FileCheck 
-check-prefix=V82ARAS %s

Actually, I added the FIXME because I don't want to fix the test in this 
commit. There's no functional change to this review I think
