I noticed today that our binary dists are getting bigger:
{{{
-rw-rw-r-- 1 simonmar GHC 118924739 2010-11-17 04:02 ghc-7.0.1-i386
-unknown-linux.tar.bz2
-rw-rw-r-- 1 simonmar GHC 112074889 2011-03-02 04:19 ghc-7.0.2-i386

-rw-rw-r-- 1 simonmar GHC 144861355 2012-04-18 06:25 ghc-7.5.20120413-i386
-unknown-linux.tar.bz2
}}}
I looked into the difference between 7.0.4 and 7.4.1, and found that it
seems to be mostly caused by GHC itself getting bigger:
{{{
-rwxrwxr-x simonmar/GHC 31280127 2011-06-14 19:59
ghc-7.0.4/ghc/stage2/build/tmp/ghc-stage2
-rwxrwxr-x simonmar/GHC 41050757 2012-04-19 20:12
ghc-7.4.1/ghc/stage2/build/tmp/ghc-stage2
}}}
the GHC binary is 25% larger, and the binary dist contains several copies
of GHC (.a, _p.a, .so, the GHC binary, haddock).
We didn't add 25% more code to GHC between 7.0.4 and 7.4.1, so why is it
25% larger? This increase isn't reflected in other libraries - in fact,
the base package is smaller in 7.4.1 than 7.0.4.
I have a horrid feeling that this is due to heavy use of INLINE/INLINABLE
in `containers`, but I hope I'm wrong.
