[PATCH] D85408: Let -basic-block-sections=labels emit basicblock metadata in a new .bb_addr_map section, instead of emitting special unary-encoded symbols.

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added inline comments.

+      getObjFileLowering().getBBAddrMapSection(*MF.getSection());
+  if (!BBAddrMapSection)
+    return;
