* Another overhaul of the recent_activity / idle GC handling (#5991)Simon Marlow2012-09-245-25/+63
| | | | | | | | | | | | | | | Improvements: - we now turn off the timer signal in the non-threaded RTS after idleGCDelay. This should make the xmonad users on #5991 happy. - we now turn off the timer signal after idleGCDelay even if the idle GC is disabled with +RTS -I0. - we now do *not* turn off the timer when profiling. - more comments to explain the meaning of the various ACTIVITY_* values
* Revert "Disable the timer signal while blocked in select() (#5991)"Simon Marlow2012-09-241-13/+4
| | | | | | | | | This reverts commit dd24d6bc37879c6b32a3d5ac4ee765e59e13501c. This attempt to fix the problem was misguided: the program might be stuck in a foreign call rather than awaitEvent(), and then the timer signal will never get disabled. The only way to turn off the timer signal in this case is in the timer interrupt handler itself.

* Include pinned memory in the stats for allocated memorySimon Marlow2012-09-212-1/+2
| | | | | This broke with the changes to the pinned object handling in 67f4ab7e6b7705a9d617c6109a8c5434ede13cae.
* Cache the result of countOccupied(gen->large_objects) as gen->n_large_words ↵Simon Marlow2012-09-213-2/+7
| | | | | | | | | (#7257) The program in #7257 was spending 90% of its time counting the live data in gen->large_objects. We already avoid doing this for small objects, but in this example the old generation was full of large objects (actually pinned ByteStrings).
* Allow allocNursery() to allocate single blocks (#7257)Simon Marlow2012-09-212-11/+13
| | | | | | | Forcing large allocations here can creates serious fragmentation in some cases, and since the large allocations are only a small optimisation we should allow the nursery to hoover up small blocks before allocating large chunks.

| * Teach the linear register allocator how to allocate more stack if necessarySimon Marlow2012-09-208-82/+189
| | | | | | | | | | | | | | | | | | This squashes the "out of spill slots" panic that occasionally happens on x86, by adding instructions to bump and retreat the C stack pointer as necessary. The panic has become more common since the new codegen, because we lump code into larger blocks, and the register allocator isn't very good at reusing stack slots for spilling (see Note [extra spill slots]).

| * Make the call to chooseBoxingStrategy lazy againSimon Peyton Jones2012-09-171-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I made it strict, as an incidental consequence of this patch: commit 5bae803a18b17bdb158a7780e6b6ac3c520e5b39 Author: Simon Peyton Jones <simonpj@microsoft.com> Date: Sat Sep 15 23:09:25 2012 +0100 Fix UNPACK with -fomit-interface-pragmas. But it's very important that chooseBoxingStrategy is lazy, else (in bigger programs with lots of recursion in types) GHC can loop. This showed up in Data.Sequence; and I think it was making haddock loop as well. Anyway this patch makes it lazy again.
