#13739: Very slow linking of profiled executables -------------------------------------+------------------------------------- Reporter: duog | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.2.1 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 duog): I've attached timings with 3 versions of ld obtained from [http://ftp.gnu.org/gnu/binutils/]. These show that 2.27 fixes the issue we're running into. Still much slower than 8.0.2 though. I would also note that I find the very large file sizes of 8.2.1-no-gc- sections relative to 8.0.2 in comment 17 weird. It looks, to my untrained eye, like many more .o files from the archives are getting pulled in. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13739#comment:21 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
