[PATCH] D108694: [RISCV] Add the zvl extension according to the v1.0 spec

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/Support/RISCVISAInfo.cpp:739
 static constexpr ImpliedExtsEntry ImpliedExts[] = {
-    {{"v"}, {ImpliedExtsV}},
-    {{"zfh"}, {ImpliedExtsZfh}},
+    {"v", {ImpliedExtsV}},
+    {"zfh", {ImpliedExtsZfh}},
----------------
Need curly braces around the strings too.


================
Comment at: llvm/lib/Support/RISCVISAInfo.cpp:805
+      unsigned ZvlLen = 0;
+      ExtName.getAsInteger(10, ZvlLen);
+      MinVLen = std::max(MinVLen, ZvlLen);
----------------
getAsInteger returns an indication of success or failure. We should check that too.  That will protect us in case someone creates an extension like "zvlfoob" in the future.
