#16242: Hadrian is too aggressive in rebuilding -------------------------------------+------------------------------------- Reporter: goldfire | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 8.6.3 (Hadrian) | 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 goldfire): I edited `Coercion.hs`. But, even if I had edited it in a meaningful way (instead of just editing a comment), I'm surprised to see the whole RTS rebuilt. I believe that's what `LAX_DEPENDENCIES` does for `make`: it assumes that, just because stage-1 has changed, it doesn't mean we need to rebuild everything that stage-1 built. Moreover, I really just wanted to run a test. So, I suppose I could do that with `build --skip=stage0//* --skip=stage1//* test --only=xyz`. Again, that's quite a mouthful. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16242#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
