off hand, once we're in in viewpattern/ pattern synonym land, ORDER of the
abstracted constructors matters!
consider
foo,bar,baz,quux,boom :: Nat -> String
plus some pattern synonyms i name "PowerOfTwo", "Even" and "Odd"
foo (PowerOfTwo x) = "power of two"
foo (Even x) = "even"
foo (Odd x) =

noticed a similar slowness building the RTS at ICFP on my MacBook Pro (macOS
10.12). I don't think my battery lasted long enough to get to stage 2.
I'm afraid I don't have any clue why it's gotten so slow, but you're not
David, when you say "dataToTag# issue", you mean #15696? It seems from the
discussion there that it is still under investigation.

Intriguing possibility. I haven't done anything to install gmp. I'm now at
home, away from this machine,
theory one:
are you setting the intree gmp flag? and/or dont have gmp the library
installed? maybe your ghc is using integer simple!
theory two: dont set -j greater than about 8 or perhaps 16? (some parts of
ghc are slower on too paralle a setup?)
those are my two off the cuff guesses

I don't think anyone knows.

many thanks.

Hey David, i'm looking at the git history andit doesn't seem to have any
commits between 8.4.3 and 8.4.4 related to the dataToTag issue
does any haskell code in the while trigger the bug on 8.4 series?

Hi devs,
I have a shiny, new iMac in my office. It's thus frustrating that it takes my
iMac longer to build GHC than my trusty 28-month-old laptop. Building devel2 on
a fresh checkout takes just about an hour. By contrast, my laptop is done after
30 minutes of work (same build settings). The
Aha. So you're viewing complete sets as a type-directed property, where we can
take a type and look up what complete sets of patterns of that type might be.
Then, when checking a pattern-match for completeness, we use the inferred type
of the pattern, access its complete sets, and if these
This has started happening when I do 'sh validate -no-clean'
"inplace/bin/ghc-cabal" configure libraries/ghc-prim dist-install

--with-ghc-pkg="/home/simonpj/5builds/HEAD-5/inplace/bin/ghc-pkg"
--disable-library-for-ghci
Sorry I wasn't clear. I'm not an expert on the topic but it seems to me
that there are two orthogonal concerns:
1) How does the checker retrieve COMPLETE sets.
Currently it seems to "attach" them to data type constructors (e.g.
Maybe). If instead it retrieved them by matching types (e.g.
What pragma syntax should other Haskell compilers use? I don't think it's
fair for GHC to have exclusive rights to the pragma syntax form the report,
and other compilers should not be relegated to using {-# X-FOOHC ... #-}.
But now we have all the same issues again.
Cheers
