Comment (by awson):

 Nope, they were only partially checked in. If you follow the commit link
 in the last post of the
 [https://sourceware.org/bugzilla/show_bug.cgi?id=19254 discussion] you
 will understand that only 32-bit bugfix (no new features at all) was
 landed. The essential part was abandoned because of Simon Brenner's idea
 that we should fix things on the GHC side making section name generation
 scheme more "windowsish" which `binutils` already has support for.

 And yes, I meant string merging when writing about string literals
 handling. At least my patch solves **sections** merging problem here. To
 make proper string merging we should, I believe, go entirely different
 way. AFAIR Walter Bright had met exactly the same problem when developing
 his `D` compiler and he used `COMDAT` to solve it. He blogged about this a
 couple of months ago.
