Unbox the Unique stored in a Name I measured that this makes the comiler allocate a bit more, but it might also make it faster and reduce residency. The extra allocation is probably just because we're not inlining enough somewhere, so I think this change is a step in the right direction.

optimisations to newUnique It turned out that newUnique was wasting one node of the splittable uniq supply per invocation: it took the current supply, split it, used the unique from one half and stored the other half in the monad. In other words, the unique in the supply stored in the monad was never used. This optimisation fixes that and adds a bit of strictness, which together lead to small reduction in allocations by the compiler, and possibly an improvement in residency (hard to tell for sure when GCs move around).

Remove most of the conflict checking and auto-hiding Now that the module restriction has been lifted, the auto-hiding is mostly not required. GHC itself automatically hides old versions of a package.

Generalise Package Support This patch pushes through one fundamental change: a module is now identified by the pair of its package and module name, whereas previously it was identified by its module name alone. This means that now a program can contain multiple modules with the same name, as long as they belong to different packages. This is a language change - the Haskell report says nothing about packages, but it is now necessary to understand packages in order to understand GHC's module system. For example, a type T from module M in package P is different from a type T from module M in package Q. Previously this wasn't an issue because there could only be a single module M in the program. The "module restriction" on combining packages has therefore been lifted, and a program can contain multiple versions of the same package. Note that none of the proposed syntax changes have yet been implemented, but the architecture is geared towards supporting import declarations qualified by package name, and that is probably the next step. It is now necessary to specify the package name when compiling a package, using the -package-name flag (which has been un-deprecated). Fortunately Cabal still uses -package-name. Certain packages are "wired in". Currently the wired-in packages are: base, haskell98, template-haskell and rts, and are always referred to by these versionless names. Other packages are referred to with full package IDs (eg. "network-1.0"). This is because the compiler needs to refer to entities in the wired-in packages, and we didn't want to bake the version of these packages into the comiler. It's conceivable that someone might want to upgrade the base package independently of GHC. Internal changes: - There are two module-related types: ModuleName just a FastString, the name of a module Module a pair of a PackageId and ModuleName A mapping from ModuleName can be a UniqFM, but a mapping from Module must be a FiniteMap (we provide it as ModuleEnv). - The "HomeModules" type that was passed around the compiler is now gone, replaced in most cases by the current package name which is contained in DynFlags. We can tell whether a Module comes from the current package by comparing its package name against the current package. - While I was here, I changed PrintUnqual to be a little more useful: it now returns the ModuleName that the identifier should be qualified with according to the current scope, rather than its original module. Also, PrintUnqual tells whether to qualify module names with package names (currently unused). Docs to follow.

Make a SplitUniqSupply contain an Int# rather than an Int The I# constructor is always removed when we make a unique later anyway, so this just saves a bit of time and allocation.

In interface files, store FastStrings rather than OccNames where possible In all cases the namespace is known from the context, so this saves 1 byte per variable binding/occurrence (a few percent per iface file).

Add -fmono-pat-binds, and make it the default In Haskell 98, pattern bindings are generalised. Thus in (f,g) = (\x->x, \y->y) both f and g will get polymorphic types. I have become convinced that generalisation for pattern-bound variables is just a bridge toof far. It is (I claim) almost never needed, and it adds significant complication. (All the more so if we add bang patterns.) So the flag -fmono-pat-binds switches off generalisation for pattern bindings. (A single variable is treated as a degnerate funtction binding.) Furthremore, as an experiment, I'm making it the default. I want to see how many progarms fail with monomorphic pattern bindings. You can recover the standard behaviour with -fno-mono-pa-binds.

Fix RULES lossage Don Stewart and Duncan Coutts encountered the following situation. f = <rhs> {-# RULES f ... #-} where f is not exported, but appears in the inlinings of other functions that are exported. Then what happened was that the desugarer produced this: M.f = f f = <rhs> where the rules get attached to the M.f. But since M.f's RHS is trivial (just f) it was unconditionally inlinined at all its call sites, thereby losing the RULES attached to it. This *is* a fragile aspect of rules. However this fix solves the problem by instead generating f = M.f M.f = <rhs> A pretty small chanage to the desugarer does the job. It still feels a little fragile, bt it's certainly more robust than before.

Experimental flag -fdicts-cheap This experimental flag, -fdicts-cheap, makes a let-binding that bind a value of dictionary type look cheap. That in turn leads to more eta expansion. Instead of f = /\a. \(d1:Ord a). let d2:Ord [a] = dfOrd a d1 in \(x:a). <stuff> which has arity 1, you get f = /\a. \(d1:Ord a). \(x:a). let d2:Ord [a] = dfOrd a d1 in <stuff> Now f has arity 2. This can cretainly waste dictionary-construction work, if f is partially applied to its dictionary argument. However it has knock-on effects. Because f has arity 2, we won't float (f Int d) out of \x. h (f Int d) Floating f out of this lambda makes it impossible for an h/f fusion rule to fire; and this unexpected loss of RULE application was the immediate reason for implementing this flag. (Roman Leshchinskiy came across this when working on array fusion.) I've implemented the change only in CoreUtils.arityType, which only affects eta expansion. I thought of putting the change in exprIsCheap, which is a more systematic place (the former calls the latter) but a) I wanted this under flag control, and the flags are not readily available to all callers of exprIsCheap b) I'm not 100% convinced that this change is a good idea, so it's reasonable to do the narrowest change that solves the immediate problem.

Add ghc and version number in .ident directive in NCG Just because we can and because every other compiler does, lets stick in an identifier directive: .ident "GHC x.y.z" into the assembly output of the NCG.

Support the GNU non-exec stack annotation system On recent GNU ELF systems one can mark an object file as not requiring an executable stack. If all objects- linked into a program have this note then the program will not use an executable stack, which is good for security (and some distros have it as a QA policy). GHC generated code does not need an executable stack so add the note to the assembly output of the native code generator (conditional on a configure test).
