  "message": "[demangler] Avoid special-subst code duplication\n\nWe need to expand special substitutions in four different ways.  This\nrefactors to only have one conversion from enum to string, and derive\nthe other 3 needs off that.\n\nThe SpecialSubstitution node is derived from the\nExpandedSpecialSubstitution.  While this may seem unintuitive, it\nworks out quite well, as SpecialSubstitution can then use the former\u0027s\ngetBaseName and remove an unneeded \u0027basic_\u0027 prefix, for those\nsubstitutions that are instantiations (to known typedef).  Similarly\nall those instantiations use the same set of template arguments (with\n\u0027basic_string\u0027, getting an additional \u0027allocator\u0027 arg).\n\nExpansion tests were added in D123134, and remain unchanged.\n\nReviewed By: MaskRay, dblaikie\n\nDifferential Revision: https://reviews.llvm.org/D125257\n\nGitOrigin-RevId: 562ce15924560d14f7062173cbdc6a9cd778e2eb\n",
