One problem is that we allocate memory in constructors that then isn't tracked, because the debugging allocator hasn't been initialised yet. The bigger problem is that for a given piece of leaking memory it's impossible to find out where it was allocated; however Valgrind gives output like this: ==6967== 8 bytes in 1 blocks are still reachable in loss record 1 of 7 ==6967== at 0x4C284A8: malloc (vg_replace_malloc.c:236) ==6967== by 0x4C28522: realloc (vg_replace_malloc.c:525) ==6967== by 0x6745E9: stgReallocBytes (RtsUtils.c:213) ==6967== by 0x68D812: setHeapAlloced (MBlock.c:91) ==6967== by 0x68D8E2: markHeapAlloced (MBlock.c:116) ==6967== by 0x68DB56: getMBlocks (MBlock.c:240) ==6967== by 0x684F55: alloc_mega_group (BlockAlloc.c:305) ==6967== by 0x6850C8: allocGroup (BlockAlloc.c:358) ==6967== by 0x69484F: allocNursery (Storage.c:390) ==6967== by 0x694ABD: allocNurseries (Storage.c:436) ==6967== by 0x6944F2: initStorage (Storage.c:217) ==6967== by 0x673E3C: hs_init (RtsStartup.c:160) which tells us exactly what the leaking bit of memory is.

PAPI can collect data for native events that are exposed by the hardware beyond the PAPI present events. The native events supported on your hardware can found by using the papi_native_avail tool. The RTS already allows users to specify PAPI preset events from the command line. This patch extends that support to allow users to specify native events. The changes needed are: 1) New option (#) for the RTS PAPI flag for native events. For example, to collect the native event 0x40000000, use ./a.out +RTS -a#0x40000000 -sstderr 2) Update the PAPI_FLAGS struct to store whether the user specified event is a papi preset or a native event 3) Update init_countable_events function to add the native events after parsing the event code and decoding the name using PAPI_event_code_to_name ] [Don't warn about unused bindings with parents in .hs-boot files; trac #3449 Ian Lynagh **20100624110351] [fix the home_imps filter to allow for 'import "this" ' Simon Marlow **20100621125535 Ignore-this: da4e605b0513afc32a4e7caa921a2c76 In the PackageImports extension, import "this" means "import from the current package". ] [Use the standard C wrapper code for the ghc-$version.exe wrapper Ian Lynagh **20100622202859 Ignore-this: 60cd3e6db3afb63e6ba9e2db3b033580 ] [Don't rely on "-packagefoo" working; use "-package foo" instead Ian Lynagh **20100622202547] [Remove unnecessary C #includes Ian Lynagh **20100622172919] [Make the ghci.exe wrapper call the right ghc.exe Ian Lynagh **20100622172247] [More updates to datalayout description in llvm BE David Terei **20100622165339 Ignore-this: b0c604fe7673b0aa7c7064694d574437 ] [Remove LlvmAs phase as the llvm opt tool now handles this phase David Terei **20100622144044 Ignore-this: b9fd8f959702b6af014e2fa654bede3 This phase originally invoked the llvm-as tool that turns a textual llvm assembly file into a bit code file for the rest of llvm to deal with.

The -no-link flag has been un-deprecated. -fno-code is now allowed with --make (#3783); the fact that it was disabled before was largely accidental, it seems. We also had some regressions in this area: it seems that -fno-code was causing a .hc file to be emitted in certain cases. I've tidied up the code, there was no need for -fno-code to be a "mode" flag, as far as I can tell. -fno-code does not emit interface files, nor does it do recompilation checking, as suggested in #3783. This would make Haddock emit interface files, for example, and I'm fairly sure we don't want to do that.

Removing this linear component fixes some pathalogical performance cases where many threads were blocked on an MVar and became unreachable simultaneously (nofib/smp/threads007), or when sending an asynchronous exception to a TSO in a long list of thread blocked on an MVar. MVar performance has actually improved by a few percent as a result of this change, slightly to my surprise. This is the final cleanup in the sequence, which let me remove the old way of waking up threads (unblockOne(), MSG_WAKEUP) in favour of the new way (tryWakeupThread and MSG_TRY_WAKEUP, which is idempotent).

Advantages: - gets rid of a locked global data structure and some tricky GC code (replacing it with some per-thread data structures and different tricky GC code :) - wakeups are more prompt: parallel/concurrent performance should benefit. I haven't seen anything dramatic in the parallel benchmarks so far, but a couple of threading benchmarks do improve a bit. - waking up a thread blocked on a blackhole is now O(1) (e.g. if it is the target of throwTo). - less sharing and better separation of Capabilities: communication is done with messages, the data structures are strictly owned by a Capability and cannot be modified except by sending messages. - this change will utlimately enable us to do more intelligent scheduling when threads block on each other. This is what started off the whole thing, but it isn't done yet (#3838). I'll be documenting all this on the wiki in due course. ] [Fix warnings (allow pushOnRunQueue() to not be inlined) Simon Marlow **20100401114559 Ignore-this: f40bfbfad70a5165a946d11371605b7d ] [remove out of date comment Simon Marlow **20100401105853 Ignore-this: 26af88dd418ee0bcda7223b3b7e4e8d2 ] [tidy up spacing in stderr traces Simon Marlow **20100326163122 Ignore-this: 16558b0433a274be217d4bf39aa4946 ] [Fix an assertion that was not safe when running in parallel Simon Marlow **20100325143656 Ignore-this: cad08fb8900eb3a475547af0189fcc47 ] [Never jump directly to a thunk's entry code, even if it is single-entry Simon Marlow **20100325114847 Ignore-this: 938da172c06a97762ef605c8fccfedf1 I don't think this fixes any bugs as we don't have single-entry thunks at the moment, but it could cause problems for parallel execution if we ever did re-introduce update avoidance. ] [Rename forgotten -dverbose-simpl to -dverbose-core2core in the docs.

The RTS then assumes that a heap-check failure has occurred and subtracts HpAlloc from Hp, although in fact it was a stack-check failure and retreating Hp will overwrite valid heap objects. The bug is that HpAlloc should only be set when Hp has been incremented by the heap check. See comments in rts/HeapStackCheck.cmm for more details.
