It will then be *very* expensive, because it runs every Core pass twice, and diff'ing Core can be almost arbitrarily costly. That being said, without `-dannot-lint` we should really have `lintAnnots pname pass guts = pass guts`. Not quite sure though how we get that much individual allocation on it, I'll investigate. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9961#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
