#4012: Compilation results are not deterministic -------------------------------------+------------------------------------- Reporter: kili | Owner: niteria Type: bug | Status: new Priority: high | Milestone: 8.6.1 Component: Compiler | Version: 6.12.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: 11362 | Blocking: 12262 Related Tickets: #10424 | Differential Rev(s): Phab:D910, | Phab:D1073, Phab:D1133, Phab:D1192, | Phab:D1268, Phab:D1360, Phab:D1373, | Phab:D1396, Phab:D1457, Phab:D1468, Wiki Page: | Phab:D1487, Phab:D1504, Phab:D1508, DeterministicBuilds | Phab:D4388 -------------------------------------+------------------------------------- Comment (by shlevy): D4388 chips away at more of this, by removing non-determinism in cost centre symbol names (which caused linking errors when doing distributed builds with nix). A unique was replaced with a 0-based index that increments in source location order for a given module, cost centre name, and cost centre type. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/4012#comment:244 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
