#15130: Hadrian doesn't rebuild changed `CoreUtils.hs` --------------------------------------+--------------------------- Reporter: tdammers | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Build System | Version: 8.4.2 Keywords: | Operating System: Linux Architecture: x86_64 (amd64) | Type of failure: Other Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: --------------------------------------+--------------------------- When compiling stage2 with Hadrian, freezing stage1 causes changes to `CoreUtils.hs` to be ignored, and `CoreUtils.hs` not being recompiled. The following steps should reproduce the problem: 1. Make a debug build with Hadrian: `./hadrian/build.sh --flavour=Devel2` 2. Rebuild with freeze1: `./hadrian/build.sh --flavour=Devel2 --freeze1` 3. Edit `compiler/coreSyn/CoreUtils.hs`, adding some change that is easily detected in the output 4. Rebuild with freeze1: `./hadrian/build.sh --flavour=Devel2 --freeze1` 5. Observe how `CoreUtils` does not appear in the list of modules Hadrian is compiling, and how changes to that file do not end up in the stage2 compiler. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15130 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
