#13535: vector test suite uses excessive memory on GHC 8.2 -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.2.1 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: #10800 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): OK, but all those call sites must be applied to the same combining- function argument (else the loop would be different in each case). So we just have lots of all to `foldlM k z`, for a particular `k` and `z`? Could we CSE those calls before inlining the `foldlM`? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13535#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
