[PATCH] D68818: [hip][cuda] Fix the extended lambda name mangling issue.

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

I agree with Richard's suggestion of just numbering all the lambdas in both modes if that's viable.



================
Comment at: clang/include/clang/AST/DeclCXX.h:587-590
+    unsigned NumExplicitCaptures : 12;
+
+    /// Has known `internal` linkage.
+    unsigned HasKnownInternalLinkage : 1;

If this field is necessary, please borrow its space from `ManglingNumber` below rather than the number of explicit captures.
