Hi,
at http://hackage.haskell.org/trac/ghc/wiki/Platforms I read, that the Sparc NCG 'is bitrotted' - does that mean, that it is unmaintained, but used by default at sparc?
No it means that GHC uses compilation via C on sparc.
I am asking because the solaris sparc system has a ghc 6.2 installed, which generates .s files. Or does NCG means something else?
When GHC compiles via C, it generates '.hc' files and uses gcc to compile these into assembly '.s' files. When GHC uses its NCG it generates '.s' files directly. In both cases it uses gcc to assemble these '.s' files into object code '.o' files. So if someone were to take up maintainership and fix the bitrotted sparc NCG then we could use -fasm again rather than the default being -fvia-C and benefit from quicker compile times. Duncan
