#12900: Common up identical info tables -------------------------------------+------------------------------------- Reporter: dobenour | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by osa1): We discussed this on the IRC channel and @ezyang pointed out two things: - Assuming this is only for merging same info tables, we can go even further by reordering fields so that {{{data T1 = T1 Int# Bool}}} and {{{data T2 = T2 Bool Int#}}} would get same info tables. This obviously needs a lot more work but saves more space. - This breaks {{{-h}}} which works even in non-profiled mode. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12900#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
