#13274: GHC library is accumulating exported symbols at a very rapid rate. -------------------------------------+------------------------------------- Reporter: Phyx- | Owner: (none) Type: task | Status: new Priority: normal | Milestone: 8.4.1 Component: Compiler | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Other Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: #5987 Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- On `20160617` libHSghc had `49610` exported symbols. This was gotten by doing `nm -g $5 | sed -nr 's/^[a-z,A-Z,0-9]+\s([A-Z])\s(.+)$/\1 \2\n/p' | sed -r 's/^.+:.*$//g' | sed '/^\s*$/d' | sort | uniq -u` on all object files given to link `libHSghc`. After rebasing on newer commit `20161015` 4 months later it now has `124966` exported symbols. This is an explosive increase in symbol count of nearly 300%. On `20170208` this is now even higher `147927` which is another big increase. Unfortunately it's not easy for me to go back to the first build since my git has been pruned. But I do have the list for the latest jump. Should be investigated why. This rate will be problematic for #5987 as it means we'll keep adding DLLs. Currently with the current head it needs to split in 3 DLLs, and it's not far from a 4th. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13274 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
