+Subject: [PATCH 2/2] [cling] Set DataLayout from our TargetMachine
+
+Otherwise LLJIT's constructor will ask the LLJITBuilder's JTMB to
+create a DataLayout. As we don't propagate the JTMB (yet -- we
+probably should!), this will be wrong if target features influence
+the DataLayout.
+
+This should fix #12293.
+
+(cherry picked from commit 254bac6cfad78ed671ec3af3d2001c52487b4c86)
