#5793: make nofib awesome ------------------------------------------+-------------------------------- Reporter: dterei | Owner: dterei Type: task | Status: new Priority: normal | Milestone: _|_ Component: NoFib benchmark suite | Version: Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: 5794 | Blocked By: | Related Tickets: ------------------------------------------+-------------------------------- Changes (by rwbarton): * cc: rwbarton@… (added) Comment: Another nofib build-system improvement I'd like to see is putting all the generated files off to the side in a `build/` directory. I often want to do two sequential nofib runs with different compiler options, and afterwards I might want to investigate one test (e.g. whichever one got slower by the most) by running the two executables with some RTS option, or comparing the disassembly of the two .o files, or whatever. That would be a lot easier if I could just `mv build/ build1/` before starting the second nofib run. I'll probably take a look at some of these projects after 7.8 is released. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/5793#comment:26> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

Could there be a flag to disable this new coverage condition? -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/1241#comment:22> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
