#13739: Very slow linking of profiled executables -------------------------------------+------------------------------------- Reporter: duog | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1-rc2 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Compile-time | (amd64) performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): I tried `objdump`-ing object files produced by 8.0.2 and 8.2.1, and they look almost identical. I have to wonder how much of this is due to GCC differences. For comparison, I just tried compiling a simple profiled executable on my machine with GCC 6.2.0, and the whole process only took about 1.5 seconds. (Compare that to the 13-second times that I experienced on my other machine with GCC 4.8.4.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13739#comment:16 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
