The original bug was a 'nameModule' panic, caused by trying to find the module of a top-level name. But TH quotes generate Internal top-level names that don't have a module, and that is generally a good thing. Fixing that in turn led to the default-method refactoring, which also makes the Name for a default method be handled in the same way as other derived names, generated in BuildTyCl via a call newImplicitBinder. Hurrah. ] [Don't do SpecConstr on NOINLINE things (Trac #4064) [email protected]**20100525112807 Ignore-this: 452be0a2cef0042fb67275c2827b5f72 Since the RULE from specialising gets the same Activation as the inlining for the Id itself there's no point in specialising a NOINLINE thing, because the rule will be permanently switched off.

However, it turns out we only need to define _POSIX_C_SOURCE and _XOPEN_SOURCE to get all the C99 stuff we need too, so there's no need for any #ifdefs.

Unfortunately an earlier fix for something else had sorted the list of packages so that it was in lexicographic order by installedPackageId, and sadly our test (cabal/shadow) didn't pick this up because the lexicographic ordering happened to work for the test.

I did quite a bit of refactoring, which improved the code by refining the types somewhat. In particular notice that in DataCon, we have dcStrictMarks :: [HsBang] dcRepStrictness :: [StrictnessMarks] The former relates to the *source-code* annotation, the latter to GHC's representation choice. ] [Make tcg_dus behave more sanely; fixes a mkUsageInfo panic [email protected]**20100506162719 Ignore-this: d000bca15b0e127e297378ded1bfb81b The tcg_dus field used to contain *uses* of type and class decls, but not *defs*. That was inconsistent, and it really went wrong for Template Haskell bracket. What happened was that foo = [d| data A = A f :: A -> A f x = x |] would find a "use" of A when processing the top level of the module, which in turn led to a mkUsageInfo panic in MkIface. The cause was the fact that the tcg_dus for the nested quote didn't have defs for A. ] [Add a HsExplicitFlag to SpliceDecl, to improve Trac #4042 [email protected]**20100506161523 Ignore-this: e4e563bac2fd831cc9e94612f5b4fa9d The issue here is that g :: A -> A f data A = A is treated as if you'd written $(f); that is the call of f is a top-level Template Haskell splice. This patch makes sure that we *first* check the -XTemplateHaskellFlag and bleat about a parse error if it's off.

I got it wrong once, and fixed it -- hence the "extra_constraints" in TcDeriv.inferConstraints. But it still wasn't right!

The meaning of the -c flag has changed (back): -c now selects one-shot compilation, but stops before linking. However, to retain backwards compatibility, -c is still allowed with --make, and means the same as --make -no-link. 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. Compiling with -fno-code is pretty quick anyway, perhaps we can get away without recompilation checking. ] [remove duplicate docs for -e in --help output (#4010) Simon Marlow <[email protected]>**20100426140642 Ignore-this: 187ff893ba8ffa0ec127867a7590e38d ] [workaround for #4003, fixes HEAD build with 6.12.2 Simon Marlow <[email protected]>**20100426103428 Ignore-this: c4bc445dc8052d4e6efef3f1daf63562 ] [Make sure all the clean rules are always included Ian Lynagh <[email protected]>**20100424181823 In particular, this fixes a problem where stage3 bits weren't being cleaned ] [Correct the name of the amd64/FreeBSD platform in PlatformSupportsSharedLibs Ian Lynagh <[email protected]>**20100424132830 We weren't getting sharedlibs on amd64/FreeBSD because of this ] [Include DPH docs in bindists Ian Lynagh <[email protected]>**20100424123101] [reinstate eta-expansion during SimplGently, to fix inlining of sequence_ Simon Marlow <[email protected]>**20100423124853 Ignore-this: 4fa0fd5bafe0d6b58fc81076f50d5f8d ] [fix 64-bit value for W_SHIFT, which thankfully appears to be not used Simon Marlow <[email protected]>**20100422213605 Ignore-this: 525c062d2456c224ec8d0e083edd3b55 ] [Add missing constant folding and optimisation for unsigned division Simon Marlow <[email protected]>**20100422213443 Ignore-this: fb10d1cda0852fab0cbcb47247498fb3 Noticed by Denys Rtveliashvili <[email protected]>, see #4004 ] [Fix the GHC API link in the main doc index.html Ian Lynagh <[email protected]>**20100422213226] [Give the right exit code in darcs-all Ian Lynagh <[email protected]>**20100421171339 Our END block was calling system, which alters $?.

This lets us remove a TSO from the list in O(1) time rather than O(n) time, by marking the list object. 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). It is now the case that only the Capability that owns a TSO may modify its state (well, almost), and this simplifies various things. More of the RTS is based on message-passing between Capabilities now. ] [eliminate some duplication with a bit of CPP Simon Marlow <[email protected]>**20100330154355 Ignore-this: 838f7d341f096ca14c86ab9c81193e36 ] [Make ioManagerDie() idempotent Simon Marlow <[email protected]>**20100401100705 Ignore-this: a5996b43cdb2e2d72e6e971d7ea925fb Avoids screeds of "event buffer overflowed; event dropped" in conc059(threaded1). ] [Move a thread to the front of the run queue when another thread blocks on it Simon Marlow <[email protected]>**20100329144521 Ignore-this: c518ff0d41154680edc811d891826a29 This fixes #3838, and was made possible by the new BLACKHOLE infrastructure.

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.

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. This bug is probably incredibly rare in practice, but I happened to be working on a test that triggers it reliably: concurrent/should_run/throwto001, compiled with -O -threaded, args 30 300 +RTS -N2, run repeatedly in a loop. ] [comments and formatting only Simon Marlow <[email protected]>**20100325104617 Ignore-this: c0a211e15b5953bb4a84771bcddd1d06 ] [Change how perl scripts get installed; partially fixes #3863 Ian Lynagh <[email protected]>**20100324171422 We now regenerate them when installing, which means the path for perl doesn't get baked in ] [Pass the location of gcc in the ghc wrapper script; partially fixes #3863 Ian Lynagh <[email protected]>**20100324171408 This means we don't rely on baking a path to gcc into the executable ] [Quote the ar path in configure Ian Lynagh <[email protected]>**20100324162043] [Remove unused cUSER_WAY_NAMES cUSER_WAY_OPTS Ian Lynagh <[email protected]>**20100324145048] [Remove unused cCONTEXT_DIFF Ian Lynagh <[email protected]>**20100324145013] [Remove unused cEnableWin32DLLs Ian Lynagh <[email protected]>**20100324144841] [Remove unused cGHC_CP Ian Lynagh <[email protected]>**20100324144656] [Fix the build for non-GNU-ar Ian Lynagh <[email protected]>**20100324132907] [Tweak the Makefile code for making .a libs; fixes trac #3642 Ian Lynagh <[email protected]>**20100323221325 The main change is that, rather than using "xargs ar" we now put all the filenames into a file, and do "ar @file".
