[GHC] #11545: Strictness signature blowup

#11545: Strictness signature blowup -------------------------------------+------------------------------------- Reporter: jscholl | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 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): | Wiki Page: -------------------------------------+------------------------------------- The following code takes a lot of memory (556MB) to compile: {{{#!hs data A = A A A A A A deriving (Eq) }}} More {{{A}}}s result in more memory consumption during compilation. Using {{{ghc -O A.hs -v -dverbose-core2core -c -ddump-simpl +RTS -s}}} it seems like the strictness signatures of (==) and (/=) blow up quite a bit. A less silly example could be the following: {{{#!hs data QuadTree a = QuadTree !Int [a] (QuadTree a) (QuadTree a) (QuadTree a) (QuadTree a) foldQuadTree :: (a -> b -> b) -> Int -> b -> QuadTree a -> b foldQuadTree f maxSize = go where go z (QuadTree size elems t1 t2 t3 t4) | size <= maxSize = foldr f z elems | otherwise = go (go (go (go z t4) t3) t2) t1 }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/11545> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #9758: By default, testsuite should clean up after successful tests

#9758: By default, testsuite should clean up after successful tests -------------------------------------+------------------------------------- Reporter: ezyang | Owner: Type: task | Status: new Priority: low | Milestone: Component: Test Suite | Version: 7.9 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Blocked By: | None/Unknown Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- A fully built GHC compiler for development takes about 1G of space. However, running the testsuite balloons this amount to 10G. Why? Because we don't clear away any test files by default. Now, it's pretty useful to have these files if you're debugging a problem. But I think it's pretty unnecessary for successful tests. So I suggest cleaning out the files automatically if the test succeeds. Tradeoff: the testsuite will take longer to run since it is cleaning up after itself. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9758> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
