Using the NCG rather + than compiling via C reduces compilation times by roughly a + half while having minimal effect on the run-time of the + compiled program (about 2-4% slower, worse for floating-point + intensive programs). + + Add the flag to GHC's command + line to enable it. + + + + Implicit parameters. + + + + Functional dependencies. + + + + New DEPRECATED pragma for marking + outdated interfaces as deprecated. + + + + New flag: , which + dumps a file M.imports that contains the + (allegedly) minimal bunch of imports needed by the current + module. + + + + New “package” system for libraries. See + for the details. + + + + The long-standing bug that caused some programs which + used trace to + exit with a deadlock error has been fixed. + + + + Trying to put into a full MVar will now + raise a PutFullMVar + exception. + + + + If a thread is about to be garbage collected, because it + is waiting on an MVar that no other thread + has access to, then it will now be sent the BlockedOnDeadMVar + exception. + + + + A thread that is found to be blocked against itself + (i.e. is black holed) is now sent a + NonTermination exception. + + + + Operations which may block, such as + takeMVar, raiseInThread, + and several I/O operations, may now receive asynchronous + exceptions even in the scope of a + blockAsyncExceptions. These are called + interruptible operations. See for more details. + + + + Result type signatures now work. + + + + A truckload of bugfixes. + + + + + + + User-visible library changes + + + + FFI. + + + + HaXml, a library for parsing and generating XML, has + been added to the text package (). + + + + The QuickCheck library for performing + functional testing has been added to the + util package. + + + + Two new experimental interfaces to arrays: + IArray for immutable arrays (), and MArray for + mutable arrays (). + + Comments on these interfaces are welcome; eventually + we'd like them to replace ByteArray, + STArray and + IOArray. + + + + New function: tryTakeMVar. + + + + MutableArray has gone away, use + STArray (see ) + instead. + + + + hPutBuf, + hPutBufBA, hGetBuf, and + hGetBufBA, have been renamed to + hPutBufFull, + hPutBufBAFull, + hGetBufFull, and + hGetBufBAFull. Functions with the old + names still exist, but have slightly different semantics. See + for more details. + + + + + + Internal changes + + + + Con is gone; the + CoreExpr type is simpler. + + + + NoRepLits have gone. + + + + Better usage info in interface files, which means less + recompilation. + + + + CCall primop is tidied up. + + + + Constant folding now done by Rules. + + + + Lots of hackery in the simplifier. + + + + Improvements in CPR and strictness analysis. + + + + + + + + + diff --git a/ghc/docs/users_guide/ug-ent.sgml b/ghc/docs/users_guide/ug-ent.sgml index 9cc71ec..bd30920 100644 --- a/ghc/docs/users_guide/ug-ent.sgml +++ b/ghc/docs/users_guide/ug-ent.sgml @@ -1,6 +1,6 @@ - + -- 1.7.10.4
