[PATCH] D151716: [RISCV] check pointer before dereference

[Wang Pengcheng via Phabricator via llvm-commits]

pcwang-thead added inline comments.


================
Comment at: llvm/lib/Support/RISCVISAInfo.cpp:705
     I += 1 + ConsumeLength;
-    if (*I == '_')
+    if (I != E && *I == '_')
       ++I;
----------------
What about:
```
  auto GoToNextExt = [&](StringRef::iterator &I, unsigned ConsumeLength) {
    I += 1 + ConsumeLength;
    if (I != Exts.end() && *I == '_')
      ++I;
  };
```
So that there is no need to make changes below.
