[PATCH] D148799: [clang] Return `std::string_view` from `TargetInfo::getClobbers()`

[David Spickett via Phabricator via cfe-commits]

> I did not set const qualifier for return type because std::string_view is constant by design. Or should I mark it const explicitly?

I'm new to string_view but everything I see backs up that it is a constant view on the data as you say. I'm not sure what making it itself const would do, not worth looking into here.

Please update the commit message (here and locally, in case you happen to be using `arc`, which prefers one and I forget which one). It should include the reasoning for the change, as we've discussed here.



================
Comment at: clang/lib/CodeGen/CGBuiltin.cpp:942
   std::string Constraints = "={@ccc},r,r,~{cc},~{memory}";
-  std::string MachineClobbers = CGF.getTarget().getClobbers();
+  std::string_view MachineClobbers CGF.getTarget().getClobbers();
   if (!MachineClobbers.empty()) {
----------------
You dropped a `=`, please make sure it compiles before updating the review.
