#9315: Weird change in allocation numbers of T9203 -------------------------------------+------------------------------------- Reporter: nomeata | Owner: simonmar Type: bug | Status: new Priority: normal | Milestone: Component: Runtime | Version: 7.9 System | Keywords: Resolution: | Operating System: Unknown/Multiple Differential Revisions: | Type of failure: None/Unknown Architecture: | Test Case: Unknown/Multiple | Blocking: Difficulty: Unknown | Blocked By: | Related Tickets: | -------------------------------------+------------------------------------- Comment (by simonmar): If we change validate to use GhcLibHcOpts=-O2 and update the tests to match, then * validate takes a minute longer * the tests now fail with a `quick` build (which we recommend for development, and I generally use) * the compiler is still not built with -O2 So I'm not convinced this is a win. BTW, on the question of -j setting, the usual way is to say `CPUS=8 ./validate` if you have an 8-core machine. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9315#comment:20 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
