* Better abstraction over run queues.Edward Z. Yang2013-01-164-14/+41
| | | | | | | | | This adds some new functions: peekRunQueue, promoteInRunQueue, singletonRunQueue and truncateRunQueue which help abstract away manual linked list manipulation, making it easier to swap in a new queue implementation. Signed-off-by: Edward Z. Yang <ezyang@mit.edu>

* Add a -rpath entry for the RTS library, so that it can find libffiIan Lynagh2013-01-041-0/+4
| | | | | | | | | | This fixes dynamic library resolution when --enable-new-dtags is used (#7062). When --enable-new-dtags is used when linking an executable, a RUNPATH as well as RPATH is set. The linker then ignores RPATH, and RUNPATH is only used for directly (not transitively) needed libraries. As the program doesn't directly need libffi, it isn't found.

* Add a write barrier for TVAR closuresSimon Marlow2012-11-1620-50/+188
| | | | | | | | | | This improves GC performance when there are a lot of TVars in the heap. For instance, a TChan with a lot of elements causes a massive GC drag without this patch. There's more to do - several other STM closure types don't have write barriers, so GC performance when there are a lot of threads blocked on STM isn't great. But fixing the problem for TVar is a good start.

| | | | | We may not assume that registers are saved across calls to unlockClosure because it could call a C function on some platforms.

* Add a new traceMarker# primop for use in profiling outputDuncan Coutts2012-10-157-0/+84
| | | | | | | | | In time-based profiling visualisations (e.g. heap profiles and ThreadScope) it would be useful to be able to mark particular points in the execution and have those points in time marked in the visualisation. The traceMarker# primop currently emits an event into the eventlog. In principle it could be extended to do something in the heap profiling too.

| * rts: Ignore signal before deleting timer. Fixes #7303.Erik de Castro Lopo2012-10-141-0/+3
| | | | | | | | | | | | | | Was getting an ocassional hang or segfault when building GHC in a Qemu user space emulation of ARM. Turned out that the ITIMER_SIGNAL was being delivered *after* the call to timer_delete(). Setting the signal to SIG_IGN before deleting the timer solves the problem.
