Comment (by Sergei Trofimovich <slyfox@…>):

 In [changeset:"b3ae47caf2f23cfd2c22c29dbfca646493ffe469/ghc" b3ae47c/ghc]:
 {{{
 #!CommitTicketReference repository="ghc"
 revision="b3ae47caf2f23cfd2c22c29dbfca646493ffe469"
 don't allow AsmTempLabel in UNREG mode (Trac #14264)

 AsmTempLabel is really a label that describes
 label in assembly output (or equivalent like LLVM IR).

 Unregisterised build does not handle it correctly.

 This change does not fix UNREG build failure in
 Ticket #14264 but reverts back to panic:
     pprCLbl AsmTempLabel
