* Avoid local label syntax for assembler on AIXHerbert Valerio Riedel2016-03-241-5/+9
| | | | | | | | | | | | | Unfortunately (for inline `__asm__()` uses), IBM's `as` doesn't seem to support local labels[1] like GNU `as` does so we need to workaround this when on AIX.

* Use the x86/Darwin implementation of Adjustors on all x86 platforms,Simon Marlow2011-06-291-1/+6

* Reorganisation of the source treeSimon Marlow2006-04-071-0/+189
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.
