#14980: Runtime performance regression with binary operations on vectors -------------------------------------+------------------------------------- Reporter: ttylec | Owner: bgamari Type: bug | Status: new Priority: high | Milestone: 8.8.1 Component: Compiler | Version: 8.2.2 Resolution: | Keywords: vector | bitwise operations Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by tdammers): Speaking of clean slates; I just noticed that `$PATH` can mess up the testing, because stack defaults to installing binaries into `~/.local/bin/`, while cabal installs either into `~/.cabal/bin` (if no sandbox is used), or into `./.cabal-sandbox/bin` (if a sandbox is used). So you have to be careful to make sure you're running the correct binary, and just relying on `$PATH` might explain while switching between configurations or build tools might appear to leave some residue. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14980#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
