* Fix dependency analysis (notably bindInstsOfLocalFuns) in TcBindssimonpj@microsoft.com2006-09-051-72/+57
| | | | | | | | | | | | | | | GHC 6.5 does enhanced dependency analysis for recursive bindings, to maximise polymorphism based on type signatures. (See Mark Jones's THIH paper.) I didn't do the bindInstsOfLocalFuns part correctly though, and jhc showed up the bug. (It only matters when you have a recursive group of two or more functions with a type signature, not at top level, which is why it hasn't shown up till now.) Test is tc207.hs

* Refactoring for derived Readsimonpj@microsoft.com2006-09-041-19/+29
| | | | | | | | | | | | | | | | | | | | There are no functional changes in this commit. But the code for derived Read is refactored to make it tidier --- and also to make it very easy if we want derived Read to parse the prefix form of infix ocnstructors. For example, data T = Int `T1` Int According to the H98 report, the derived Read instance will parse infix uses of T1, but not prefix uses (T1 4 3). It's arguable that it should parse both -- and easy to implement, but it would cause a little bit of code bloat. Similarly records. Anyway this commit doesn't implement the change; just makes it easy to do so.

* don't closeMutex() the Capability lockSimon Marlow2006-08-311-2/+4
| | | | | | | | | | | | | There might be threads in foreign calls that will attempt to return via resumeThread() and grab this lock, so we can't safely destroy it. Fixes one cause of internal error: ASSERTION FAILED: file Capability.c, line 90 although I haven't repeated that assertion failure in the wild, only with a specially crafted test case, so I can't be sure I really got it.

| | | | | | | To avoid IO requests completing only to discover that the completed_table_sema has been CloseHandle()'d. This all looks a bit wrong, though: we shouldn't really be waiting for these requests to complete, they might take forever.
* Windows: make some soft failures into fatal errorsSimon Marlow2006-08-301-5/+10
| | | | | | Some of the memory allocation calls were being checked for error, but the RTS was printing a message and continuing. These error cases lead to crashes later, so better to just fail immediately.
* MAYBE_GC: initialise HpAllocSimon Marlow2006-08-301-0/+1
| | | | | | | | | HpAlloc was not being set when returning to the scheduler via MAYBE_GC(), which at the least was just wrong (the scheduler might allocate a large block more than once), and at worst could lead to crashes if HpAlloc contains garbage. Fixes at least one threaded2 test on Windows.
