#13564: Why does memory usage increase so much during CoreTidy? -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: rwbarton Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.1 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 rwbarton): After adding `seqUnfolding` there is still a tall but narrow spike in the heap profile. I found that this spike went away with `-v`, so I added a `seqBinds` which also eliminates the spike. Trac won't let me upload another heap profile PDF though. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13564#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
