[LLVM][GVN] fix a typo in comment

[ksyx]

Politely ping. This is a simple fix of typo in comment.

LGTM, thanks! (usually you should try to add suitable reviewers to your patch, otherwise the chances that someone spots it are greatly decreased)

[xgupta]

Instead of committing, you closed the revision @ksyx, typo is still present :)

[ksyx]

The commit was actually made but with some mistake in commit msg, sorry for that. Commit here: https://reviews.llvm.org/rG4125cabce1374209843393d1e9474efea58cbeaf

No need to say sorry, actually if you search the same keyword in GVN.cpp in main branch, you can still find it. see: https://github.com/llvm/llvm-project/blob/main/llvm/lib/Transforms/Scalar/GVN.cpp#L1926

I guess some magic did happen here by Phabricator.

BTW, you could check it in directly if this patch only contains comment changes or new tests. And it may be better to add NFC keyword to the title.

llvm/lib/Transforms/Scalar/GVN.cpp

if (AnalyzeLoadAvailability(L, Dep, L->getPointerOperand(), AV)) {
 
     // Replace the load!
     patchAndReplaceAllUsesWith(L, AvailableValue);
     markInstructionForDeletion(L);
     if (MSSAU)
       MSSAU->removeMemoryAccess(L);
     ++NumGVNLoad;
     reportLoadElim(L, AvailableValue, ORE);
-    // Tell MDA to rexamine the reused pointer since we might have more
+    // Tell MDA to reexamine the reused pointer since we might have more
     // information after forwarding it.
     if (MD && AvailableValue->getType()->isPtrOrPtrVectorTy())
       MD->invalidateCachedPointerInfo(AvailableValue);
     return true;
   }
 
   return false;
 }
