#11781: Improve common sub-expression -------------------------------------+------------------------------------- Reporter: simonpj | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2074 Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Well that's remarkable. A 17% change compiler allocation is huge. Oh hang on. Maybe the program being compiled is changing size! Try `-dshow-passes` before and after. Or, to put it another way, does a ''stage1'' compiler show the same difference in allocation? Do you see what I mean? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11781#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
