#8900: Strictness analysis regression --------------------------------------------+------------------------------ Reporter: tibbe | Owner: Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 7.8.1-rc2 Resolution: fixed | Keywords: Operating System: MacOS X | Architecture: x86_64 Type of failure: Runtime performance bug | (amd64) Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: --------------------------------------------+------------------------------ Comment (by tibbe): I've looked a bit more closely and one difference between 7.6.3 and HEAD is the extra stack spilling before the eval check I reported in #8905. Another difference is that the recursive call appears as {{{ jump $wpoly_go_info; // [R6, R5, R4, R3, R2] }}} in 7.6.3 but as {{{ call $wpoly_go_info(R6, R5, R4, R3, R2) returns to c56A, args: 8, res: 8, upd: 8; }}} in HEAD. I don't know if this is just a syntactic difference. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8900#comment:23 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
