#13745: Investigate compile-time regressions in regex-tdfa-1.2.2 -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: task | Status: new Priority: high | Milestone: 8.2.2 Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by dfeuer): I was able to get enough to compare the results of `LiberateCase`. Things generally look the same at the top level, but after the `SetLevels` patch there's a bunch more local code. Everything is rather huge, so it's hard to see just what the deal is, but interestingly it really seems to be ''added'' code more than ''replaced'' code. Virtually everything that used to be there is still there, but now there's more. I'll attach diffable dump files. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13745#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
