GHC is bloated

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

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.
