+Subject: [PATCH 2/2] LLVM13 changed MCContext constructor
+
+For LLVM13, MCContext constructor changed.
+In the list of arguments appeared MCSubtargetInfo which is not used by us.
+ObjectFileInfo was removed from the list of arguments, so we need to set
+it in the next command.
+
+Upstream-Status: Backport
