#14741: High-memory usage during compilation using Template Haskell -------------------------------------+------------------------------------- Reporter: donatello | Owner: sighingnow Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4384 Wiki Page: | -------------------------------------+------------------------------------- Comment (by donatello): Thank you for the fix, it looks promising - but I am not sure if the problem is completely solved. The profiling output says that total allocations were reduced from 4.7GB to 1.3GB, which is 3.5X improvement. However, the goal in my initial program was to embed ~100MB of static data in my program - whereas the bug demonstrates the problem with a 3MB embedded string. Is there any way I could get a built version of the ghc master for 64-bit x86 Linux (from a CI server perhaps), so I could try it out myself? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14741#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
