Make forkProcess work with +RTS -N Consider this experimental for the time being. There are a lot of things that could go wrong, but I've verified that at least it works on the test cases we have. I also did some API cleanups while I was here. Previously we had: Capability * rts_eval (Capability *cap, HaskellObj p, /*out*/HaskellObj *ret); but this API is particularly error-prone: if you forget to discard the Capability * you passed in and use the return value instead, then you're in for subtle bugs with +RTS -N later on. So I changed all these functions to this form: void rts_eval (/* inout */ Capability **cap, /* in */ HaskellObj p, /* out */ HaskellObj *ret) It's much harder to use this version incorrectly, because you have to pass the Capability in by reference.

Fix trac # 5486 LLVM has a problem when the user imports some FFI types like memcpy and memset in a manner that conflicts with the types that GHC uses internally. So now we pre-initialise the environment with the most general types for these functions.

Allow full constraint solving under a for-all (Trac #5595) The main idea is that when we unify forall a. t1 ~ forall a. t2 we get constraints from unifying t1~t2 that mention a. We are producing a coercion witnessing the equivalence of the for-alls, and inside *that* coercion we need bindings for the solved constraints arising from t1~t2. We didn't have way to do this before. The big change is that here's a new type TcEvidence.TcCoercion, which is much like Coercion.Coercion except that there's a slot for TcEvBinds in it. This has a wave of follow-on changes. Not deep but broad. * New module TcEvidence, which now contains the HsWrapper TcEvBinds, EvTerm etc types that used to be in HsBinds * The typechecker works exclusively in terms of TcCoercion. * The desugarer converts TcCoercion to Coercion * The main payload is in TcUnify.unifySigmaTy. This is the function that had a gross hack before, but is now beautiful. * LCoercion is gone! Hooray. Many many fiddly changes in conssequence. But it's nice.

Move includes/DerivedConstants.h and includes/GHCConstants.h into dist dirs When they existed, they were getting included in the includes_H_FILES variable (as it uses wildcard to find all header files). But the .depends files for the programs that generate the headers depend on $(includes_H_FILES), so the .depends files looked out-of-date once the headers had been created. This caused unnecessary make reinvocations. So now we put them in dist* directories, where they ought to be anyway.

Use touchy rather than touch when building on Windows With Windows 7 in a vitrual box VM on OS X, some very odd things happen with dates and time stamps when SSHing into cygwin. e.g. here the "Change" time is in the past: $ date; touch foo; stat foo Fri Dec 2 16:58:07 GMTST 2011 File: `foo' Size: 0 Blocks: 0 IO Block: 65536 regular empty file Device: 540aba0bh/1409989131d Inode: 562949953592977 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 1000/ ian) Gid: ( 513/ None) Access: 2011-12-02 16:58:07.414457900 +0000 Modify: 2011-12-02 16:58:07.414457900 +0000 Change: 2011-12-02 16:58:03.495141800 +0000 Birth: 2011-12-02 16:57:57.731469900 +0000 And if we copy such a file, then the copy is older (as determined by the "Modify" time) than the original: $ date; touch foo; stat foo; cp foo bar; stat bar Fri Dec 2 16:59:10 GMTST 2011 File: `foo' Size: 0 Blocks: 0 IO Block: 65536 regular empty file Device: 540aba0bh/1409989131d Inode: 1407374883725128 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 1000/ ian) Gid: ( 513/ None) Access: 2011-12-02 16:59:10.118457900 +0000 Modify: 2011-12-02 16:59:10.118457900 +0000 Change: 2011-12-02 16:59:06.189477700 +0000 Birth: 2011-12-02 16:57:57.731469900 +0000 File: `bar' Size: 0 Blocks: 0 IO Block: 65536 regular empty file Device: 540aba0bh/1409989131d Inode: 281474976882512 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 1000/ ian) Gid: ( 513/ None) Access: 2011-12-02 16:59:06.394555800 +0000 Modify: 2011-12-02 16:59:06.394555800 +0000 Change: 2011-12-02 16:59:06.395532400 +0000 Birth: 2011-12-02 16:58:40.921899600 +0000 This means that make thinks that things are out of date when it shouldn't, so reinvokes itself repeatedly until the MAKE_RESTARTS infinite-recursion test triggers. The touchy program, like most other programs, creates files with both Modify and Change in the past, which is still a little odd, but is consistent, so doesn't break make.

More changes aimed at improving call stacks. - Attach a SrcSpan to every CostCentre. This had the side effect that CostCentres that used to be merged because they had the same name are now considered distinct; so I had to add a Unique to CostCentre to give them distinct object-code symbols. - New flag: -fprof-auto-calls. This flag adds an automatic SCC to every call site (application, to be precise). This is typically more useful for call stacks than annotating whole functions. Various tidy-ups at the same time: removed unused NoCostCentre constructor, and refactored a bit in Coverage.lhs. The call stack we get from traceStack now looks like this: Stack trace: Main.CAF (<entire-module>) Main.main.xs (callstack002.hs:18:12-24) Main.map (callstack002.hs:13:12-16) Main.map.go (callstack002.hs:15:21-34) Main.map.go (callstack002.hs:15:21-23) Main.f (callstack002.hs:10:7-43)

Fix a scheduling bug in the threaded RTS The parallel GC was using setContextSwitches() to stop all the other threads, which sets the context_switch flag on every Capability. That had the side effect of causing every Capability to also switch threads, and since GCs can be much more frequent than context switches, this increased the context switch frequency. When context switches are expensive (because the switch is between two bound threads or a bound and unbound thread), the difference is quite noticeable. The fix is to have a separate flag to indicate that a Capability should stop and return to the scheduler, but not switch threads. I've called this the "interrupt" flag.
