#8211: ghc -c recompiles TH every time while --make doesn't -------------------------+------------------------------------------------- Reporter: nh2 | Owner: Type: bug | Status: new Priority: | Milestone: normal | Version: 7.6.3 Component: | Operating System: Unknown/Multiple Compiler | Type of failure: Compile-time performance bug Keywords: | Test Case: Architecture: | Blocking: Unknown/Multiple | Difficulty: | Unknown | Blocked By: | Related Tickets: | -------------------------+------------------------------------------------- https://github.com/nh2/ghc-bug-recompiles-th-on-c {{{ ghc -c Test.hs # compiles ghc -c Test.hs # compiles (and loads TH) again }}} I would expect ghc to print {{{ compilation IS NOT requried }}} since ghc --make does not recompile either, and the created .hi and .o files are identical. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8211 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
