#10664: T8131 times out on master -------------------------------------+------------------------------------- Reporter: bgamari | Owner: bgamari Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by Ben Gamari ): In [changeset:"64b6733e217f32feb8c4872096749c6f417d0c39/ghc" 64b6733e/ghc]: {{{ #!CommitTicketReference repository="ghc" revision="64b6733e217f32feb8c4872096749c6f417d0c39" CmmParse: Don't force alignment in memcpy-ish operations This was initially made in 681973c31c614185229bdae4f6b7ab4f6e64753d. Here I wanted to enforce that the alignment passed to %memcpy was a constant expression, as this is required by LLVM. However, this breaks the knot-tying done in `loopDecls`, causing T8131 to hang. Here I remove the `seq` and mark T8131 as `expect_broken` in the case of the NCG, which doesn't force the alignment in this case. Fixes #10664. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10664#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
