[PATCH] D117854: [RISCV] Decouple Zve* extensions and the V extension.

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: clang/lib/Sema/SemaChecking.cpp:3978
   for (StringRef F : ReqFeatures) {
-    if (TI.hasFeature(F))
-      continue;
-
-    // If the feature is 64bit, alter the string so it will print better in
-    // the diagnostic.
-    if (F == "64bit")
-      F = "RV64";
-
-    // Convert features like "zbr" and "experimental-zbr" to "Zbr".
-    F.consume_front("experimental-");
-    std::string FeatureStr = F.str();
-    FeatureStr[0] = std::toupper(FeatureStr[0]);
+    SmallVector<StringRef> ReqOpFeatures;
+    F.split(ReqOpFeatures, '|');
----------------
Is this change testable?


================
Comment at: llvm/lib/Support/RISCVISAInfo.cpp:697
   bool HasZvl = MinVLen != 0;
 
   if (HasE && !IsRv32)
----------------
Should we check that Zve and V are not specified together?
