- Release notes for version 4.07 (May 2000)
-
-
- User-visible compiler changes
-
-
-
- New profiling subsystem, based on cost-centre stacks.
- See .
-
-
-
- The x86 native code generator has been reworked
- considerably, and now works reliably. 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).
-
- The NCG is used by default for non-optimising compiles.
- You can use it with by adding the
- flag to GHC's command
- line, after .
-
-
-
- Implicit parameters. This Haskell extension gives a
- statically-typed version of dynamic scoping that avoids the
- worst problems of dynamic scoping in lisp. See the
- POPL paper
- for more details. It is enabled by .
-
-
-
-
- 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- outdated interfaces as deprecated.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
-
-
-
- The FFI has been revised and expanded; see , , and .
-
-
-
- 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,
- MutableArray, IOArray,
- and STArray.
-
-
-
- New function: tryTakeMVar.
-
-
-
- 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 is now done by Rules.
-
-
-
- Lots of hackery in the simplifier.
