#16069: Proposal to resolve some confusion about stages in Hadrian -------------------------------------+------------------------------------- Reporter: mpickering | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by snowleopard): This simplification is something I wanted to do for a while, but there is an important question to answer: are we going to build Haddock using Stage1 GHC or Stage2 GHC? The Make build system builds Haddock using Stage2 GHC. I therefore copy my question from the GitHub issue (https://github.com/snowleopard/hadrian/issues/661): We know that building Haddock with Stage1 GHC works, but is this the right thing to do? Why does the Make build system uses the Stage2 GHC to build Haddock? Is it OK for Hadrian to deviate from Make in this respect? If the answer to the above is "It is OK for Hadrian to use Stage1 GHC to build Haddock" then I'll happily support this proposal. However, if the answer is "Hadrian must also use Stage2 GHC to build Haddock" then I'm afraid this proposal means significantly longer build times, since now we'll need to build Stage2 libraries, just in order to build Haddock and docs. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16069#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
