#13220: Performance regressions in testsuite from join points -------------------------------------+------------------------------------- Reporter: lukemaurer | Owner: lukemaurer Type: bug | Status: new Priority: highest | Milestone: 8.2.1 Component: Compiler | Version: 8.1 Resolution: | Keywords: JoinPoints Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): And does this address Joachim's comment on [https://phabricator.haskell.org/rGHC2effe18ab51d]? {{{ This might be interesting for @lukemaurer: According to https://perf.haskell.org/ghc/#revision/2effe18ab51d66474724d38b20e49cc1b8738... this patch undid the effect of join points on fannkuch-redux (i..e allocation goes up by 1318762.9%, but runtime goes down by 5%). Was this ever cleared up? Also, integer runtime goes up by 13%, and hidden by 6%, and code size generally by around 4%. Expected? }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13220#comment:31 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
