* Reorganisation of the source treeSimon Marlow2006-04-071-201/+0
| | | | | | | | | | | | | | | Most of the other users of the fptools build system have migrated to Cabal, and with the move to darcs we can now flatten the source tree without losing history, so here goes. The main change is that the ghc/ subdir is gone, and most of what it contained is now at the top level. The build system now makes no pretense at being multi-project, it is just the GHC build system. No doubt this will break many things, and there will be a period of instability while we fix the dependencies. A straightforward build should work, but I haven't yet fixed binary/source distributions. Changes to the Building Guide will follow, too.
* Parse OPTIONS properly and cache the result.Lemmih2006-03-101-0/+201
Use the lexer to parse OPTIONS, LANGUAGE and INCLUDE pragmas. This gives us greater flexibility and far better error messages. However, I had to make a few quirks: * The token parser is written manually since Happy doesn't like lexer errors (we need to extract options before the buffer is passed through 'cpp'). Still better than manually parsing a String, though. * The StringBuffer API has been extended so files can be read in blocks. I also made a new field in ModSummary called ms_hspp_opts which stores the updated DynFlags. Oh, and I took the liberty of moving 'getImports' into HeaderInfo together with 'getOptions'.
