================
Comment at: llvm/lib/Support/RISCVISAInfo.cpp:820
+        errc::invalid_argument,
+        "zvk* requires v or zve* extension to also be specified");
+
----------------
Put single quotes around extension names in the error messages. I fixed the other error messages last week


================
Comment at: llvm/lib/Target/RISCV/RISCVFeatures.td:495
+                       "'Zvknhb' (Vector SHA-2. (SHA-256 and SHA-512))",
+                       [FeatureStdExtZvknha]>;
+def HasStdExtZvknhaOrZvknhb  : Predicate<"Subtarget->hasStdExtZvknha() || Subtarget->hasStdExtZvknhb()">,
----------------
Zvknhb implies Zvknha here it needs to imply it in RISCVISAInfo.cpp too.


================
Comment at: llvm/lib/Target/RISCV/RISCVFeatures.td:496
+                       [FeatureStdExtZvknha]>;
+def HasStdExtZvknhaOrZvknhb  : Predicate<"Subtarget->hasStdExtZvknha() || Subtarget->hasStdExtZvknhb()">,
+                                AssemblerPredicate<(any_of FeatureStdExtZvknha, FeatureStdExtZvknhb),
----------------
Line 495 has Zvknhb implying Zvknha which would make it sufficient to only check HasStdExtZknha. I'm not sure if this code should be changed or the implies at line 495.
