Remove the optimisation of avoiding scavenging for certain objects Some objects don't need to be scavenged, in particular if they have no pointers. This seems like an obvious optimisation, but in fact it only accounts for about 1% of objects (in GHC, for example), and the extra complication means it probably isn't worth doing.

GC refactoring: make evacuate() take an StgClosure** Change the type of evacuate() from StgClosure *evacuate(StgClosure *); to void evacuate(StgClosure **); So evacuate() itself writes the source pointer, rather than the caller. This is slightly cleaner, and avoids a few memory writes: sometimes evacuate() doesn't move the object, and in these cases the source pointer doesn't need to be written. It doesn't have a measurable impact on performance, though.

Initial parallel GC support eg. use +RTS -g2 -RTS for 2 threads. Only major GCs are parallelised, minor GCs are still sequential. Don't use more threads than you have CPUs. It works most of the time, although you won't see much speedup yet. Tuning and more work on stability still required.

Refactoring of the GC in preparation for parallel GC This patch localises the state of the GC into a gc_thread structure, and reorganises the inner loop of the GC to scavenge one block at a time from global work lists in each "step". The gc_thread structure has a "workspace" for each step, in which it collects evacuated objects until it has a full block to push out to the step's global list. Details of the algorithm will be on the wiki in due course. At the moment, THREADED_RTS does not compile, but the single-threaded GC works (and is 10-20% slower than before).

Fix performance regression: re-instate -funbox-strict-fields Yikes! While investigating the increase in code size with GHC 6.8 relative to 6.6, I noticed that in the transition to Cabal for the libraries we lost -funbox-strict-fields, which is more or less depended on by the IO library for performance. I'm astonished that we didn't notice this earlier! To reduce the chances of this happening again, I put -funbox-strict-fields in the OPTIONS_GHC pragma of the modules that need it. {-# UNPACK #-} pragmas would be better, though.
