107+

108+Note: The `cleanGit` call will exclude any files not in the index file

109+in the local `.git` directory. This is extremely useful as it avoids

110+unwanted builds (for instance when the contents of `dist-newstyle` are

111+modified by cabal).

112+

126+The resulting shell will include all the dependencies of the local packages

127+listed in your `cabal.project` file (but it will not build those local

128+packages).

129+

130+Inside the shell use `cabal new-build` and `cabal new-repl` to work on the

131+cabal project as you normally would. They will use the packages provided

132+by nix whenever possible.

133+

134+It is a good idea to add `write-ghc-environment-files: never` to your

135+`cabal.project` file to prevent unwanted `.ghc.environment.*` files

136+(they will prevent subsequent `nix-shell` invocations from working

137+properly).

138+

139+Adding an `index-state` to your `cabal.project` can pin the plan used so that

3+We believe that imports from derivations (IFDs) provide tremendous

5+poor tooling and ci support for them. We do not believe

6+that poor tooling or ci support should cripple nix capability

8+IFDs.

10+We do note however that there are users who prefer to

11+have IFD-free expressions. For this group of users we

12+detail how to expand the IFD dependent high level functions

13+into their IFD free building blocks.

4+Subject: [PATCH] Stop the linker panic

6+If we fail to initialize the liker properly, we still set the `initLinkerDone`. In fact we even set that prior to actually initializing the linker. However if the linker initialization fails, we the `Done` state is still true. As such we run into the `Dynamic Linker not initialised` error. Which while technically corret is confusing as it pulls the attation away from the real issue.

8+This change puts the Done state into an MVar, and as such ensureing that all parallel access needs to wait for the linker to be actually initialized, or try to re-initilize if it fails.

3+Date: Wed, 13 Mar 2019 11:46:56 +0000

4+Subject: [PATCH] Visibility: handle multiple units with the same name

6+Fixes #16228. The included test case is adapted from the reproduction in

7+the issue, and fails without this patch.

9+------

10+

11+We compute an initial visilibity mapping for units based on what is

12+present in the package databases. To seed this, we compute a set of all

13+the package configs to add visibilities for.

14+

15+However, this set was keyed off the unit's *package name*. This is

16+correct, since we compare packages across databases by version. However,

17+we would only ever consider a single, most-preferable unit from the

18+database in which it was found.

19+

20+The effect of this was that only one of the libraries in a Cabal package

21+would be added to this initial set. This would cause attempts to use

22+modules from the omitted libraries to fail, claiming that the package

23+was hidden (even though `ghc-pkg` would correctly show it as visible).

24+

25+The solution is simple: consider all units that are equi-preferable

26+with the most-preferable unit.

27+

28+------

29+

30+Why wasn't this bug apparent to all people trying to use sub-libraries

31+in Cabal? The answer is that Cabal explicitly passes `-package` and

32+`-package-id` flags for all the packages it wants to use, rather than

33+relying on the state of the package database. So this bug only really

34+affects people who are trying to use package databases produced by Cabal

35+outside of Cabal itself.

36+

37+One particular example of this is the way that the

38+Nixpkgs Haskell infrastructure provides wrapped GHCs: typically these

39+are equipped with a package database containing all the needed

40+package dependencies, and the user is not expected to pass

41+`-package` flags explicitly.

22+-Note [Produce big objects on Windows]

23+-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

24+-

25+-The Windows Portable Executable object format has a limit of 32k sections, which

26+-we tend to blow through pretty easily. Thankfully, there is a "big object"

27+-extension, which raises this limit to 2^32. However, it must be explicitly

28+-enabled in the toolchain:

29+-

30+- * the assembler accepts the -mbig-obj flag, which causes it to produce a

31+- bigobj-enabled COFF object.

32+-

33+- * the linker accepts the --oformat pe-bigobj-x86-64 flag. Despite what the name

34+- suggests, this tells the linker to produce a bigobj-enabled COFF object, no a

35+- PE executable.

36+-

37+-We must enable bigobj output in a few places:

38+-

39+- * When merging object files (DriverPipeline.joinObjectFiles)

40+-

41+- * When assembling (DriverPipeline.runPhase (RealPhase As ...))

42+-

43+-Unfortunately the big object format is not supported on 32-bit targets so

44+-none of this can be used in that case.

1284+-section "The word size story."

1285+- {Haskell98 specifies that signed integers (type {\tt Int})

1286+- must contain at least 30 bits. GHC always implements {\tt

1287+- Int} using the primitive type {\tt Int\#}, whose size equals

1288+- the {\tt MachDeps.h} constant {\tt WORD\_SIZE\_IN\_BITS}.

1289+- This is normally set based on the {\tt config.h} parameter

1290+- {\tt SIZEOF\_HSWORD}, i.e., 32 bits on 32-bit machines, 64

1291+- bits on 64-bit machines. However, it can also be explicitly

1292+- set to a smaller number, e.g., 31 bits, to allow the

1293+- possibility of using tag bits. Currently GHC itself has only

1294+- 32-bit and 64-bit variants, but 30 or 31-bit code can be

1295+- exported as an external core file for use in other back ends.

1296+-

1297+- GHC also implements a primitive unsigned integer type {\tt

1298+- Word\#} which always has the same number of bits as {\tt

1299+- Int\#}.

1300+-

1301+- In addition, GHC supports families of explicit-sized integers

1302+- and words at 8, 16, 32, and 64 bits, with the usual

1303+- arithmetic operations, comparisons, and a range of

1304+- conversions. The 8-bit and 16-bit sizes are always

1305+- represented as {\tt Int\#} and {\tt Word\#}, and the

1306+- operations implemented in terms of the the primops on these

1307+- types, with suitable range restrictions on the results (using

1308+- the {\tt narrow$n$Int\#} and {\tt narrow$n$Word\#} families

1309+- of primops. The 32-bit sizes are represented using {\tt

1310+- Int\#} and {\tt Word\#} when {\tt WORD\_SIZE\_IN\_BITS}

1311+- $\geq$ 32; otherwise, these are represented using distinct

1312+- primitive types {\tt Int32\#} and {\tt Word32\#}. These (when

1313+- needed) have a complete set of corresponding operations;

1314+- however, nearly all of these are implemented as external C

1315+- functions rather than as primops. Exactly the same story

1316+- applies to the 64-bit sizes. All of these details are hidden

1317+- under the {\tt PrelInt} and {\tt PrelWord} modules, which use

1318+- {\tt \#if}-defs to invoke the appropriate types and

1319+- operators.

1320+-

1321+- Word size also matters for the families of primops for

1322+- indexing/reading/writing fixed-size quantities at offsets

1323+- from an array base, address, or foreign pointer. Here, a

1324+- slightly different approach is taken. The names of these

1325+- primops are fixed, but their {\it types} vary according to

1326+- the value of {\tt WORD\_SIZE\_IN\_BITS}. For example, if word

1327+- size is at least 32 bits then an operator like

1328+- \texttt{indexInt32Array\#} has type {\tt ByteArray\# -> Int\#

1329+- -> Int\#}; otherwise it has type {\tt ByteArray\# -> Int\# ->

1330+- Int32\#}. This approach confines the necessary {\tt

1331+- \#if}-defs to this file; no conditional compilation is needed

1332+- in the files that expose these primops.

1333+-

1334+- Finally, there are strongly deprecated primops for coercing

1335+- between {\tt Addr\#}, the primitive type of machine

1336+- addresses, and {\tt Int\#}. These are pretty bogus anyway,

1337+- but will work on existing 32-bit and 64-bit GHC targets; they

1338+- are completely bogus when tag bits are used in {\tt Int\#},

1339+- so are not available in this case. }

2118+-section "Small Arrays"

2119+-

2120+- {Operations on {\tt SmallArray\#}. A {\tt SmallArray\#} works

2121+- just like an {\tt Array\#}, but with different space use and

2122+- performance characteristics (that are often useful with small

2123+- arrays). The {\tt SmallArray\#} and {\tt SmallMutableArray#}

2124+- lack a `card table'. The purpose of a card table is to avoid

2125+- having to scan every element of the array on each GC by

2126+- keeping track of which elements have changed since the last GC

2127+- and only scanning those that have changed. So the consequence

2128+- of there being no card table is that the representation is

2129+- somewhat smaller and the writes are somewhat faster (because

2130+- the card table does not need to be updated). The disadvantage

2131+- of course is that for a {\tt SmallMutableArray#} the whole

2132+- array has to be scanned on each GC. Thus it is best suited for

2133+- use cases where the mutable array is not long lived, e.g.

2134+- where a mutable array is initialised quickly and then frozen

2135+- to become an immutable {\tt SmallArray\#}.

3175+--- So we never have to worry about floating the pointer reference

3176+--- outside a validity test. At the moment, has_side_effects blocks

3209+--- its contents with a thunk of the form (fst (f x)). This can be done using an

3930+-{- Note [dataToTag#]

3931+-~~~~~~~~~~~~~~~~~~~~

3932+-The dataToTag# primop should always be applied to an evaluated argument.

3933+-The way to ensure this is to invoke it via the 'getTag' wrapper in GHC.Base:

3934+- getTag :: a -> Int#

3935+- getTag !x = dataToTag# x

3936+-

3937+-But now consider

3938+- \z. case x of y -> let v = dataToTag# y in ...

3939+-

3940+-To improve floating, the FloatOut pass (deliberately) does a

3941+-binder-swap on the case, to give

3942+- \z. case x of y -> let v = dataToTag# x in ...

3943+-

3944+-Now FloatOut might float that v-binding outside the \z. But that is

3945+-bad because that might mean x gest evaluated much too early! (CorePrep

3946+-adds an eval to a dataToTag# call, to ensure that the argument really is

3947+-evaluated; see CorePrep Note [dataToTag magic].)

3948+-

3949+-Solution: make DataToTag into a can_fail primop. That will stop it floating

3950+-(see Note [PrimOp can_fail and has_side_effects] in PrimOp). It's a bit of

3951+-a hack but never mind.

4072+- {\tt a}. If you need to guarantee a specific order of evaluation,

4073+- you must use the function {\tt pseq} from the "parallel" package. }

4074+-

4075+-pseudoop "unsafeCoerce#"

4076+- a -> b

4077+- { The function {\tt unsafeCoerce\#} allows you to side-step the typechecker entirely. That

4078+- is, it allows you to coerce any type into any other type. If you use this function,

4079+- you had better get it right, otherwise segmentation faults await. It is generally

4080+- used when you want to write a program that you know is well-typed, but where Haskell's

4081+- type system is not expressive enough to prove that it is well typed.

4082+-

4083+- The following uses of {\tt unsafeCoerce\#} are supposed to work (i.e. not lead to

4084+- spurious compile-time or run-time crashes):

4085+-

4086+- * Casting any lifted type to {\tt Any}

4087+-

4088+- * Casting {\tt Any} back to the real type

4089+-

4090+- * Casting an unboxed type to another unboxed type of the same size.

4091+- (Casting between floating-point and integral types does not work.

4092+- See the {\tt GHC.Float} module for functions to do work.)

4093+-

4094+- * Casting between two types that have the same runtime representation. One case is when

4095+- the two types differ only in "phantom" type parameters, for example

4096+- {\tt Ptr Int} to {\tt Ptr Float}, or {\tt [Int]} to {\tt [Float]} when the list is

4097+- known to be empty. Also, a {\tt newtype} of a type {\tt T} has the same representation

4098+- at runtime as {\tt T}.

4099+-

4100+- Other uses of {\tt unsafeCoerce\#} are undefined. In particular, you should not use

4101+- {\tt unsafeCoerce\#} to cast a T to an algebraic data type D, unless T is also

4102+- an algebraic data type. For example, do not cast {\tt Int->Int} to {\tt Bool}, even if

4103+- you later cast that {\tt Bool} back to {\tt Int->Int} before applying it. The reasons

4104+- have to do with GHC's internal representation details (for the cognoscenti, data values

4105+- can be entered but function closures cannot). If you want a safe type to cast things

4106+- to, use {\tt Any}, which is not an algebraic data type.

4107+-

4108+- }

4109+-

4110+--- NB. It is tempting to think that casting a value to a type that it doesn't have is safe

4111+--- as long as you don't "do anything" with the value in its cast form, such as seq on it. This

4112+--- isn't the case: the compiler can insert seqs itself, and if these happen at the wrong type,

4113+--- Bad Things Might Happen. See bug #1616: in this case we cast a function of type (a,b) -> (a,b)

4114+--- to () -> () and back again. The strictness analyser saw that the function was strict, but

4115+--- the wrapper had type () -> (), and hence the wrapper de-constructed the (), the worker re-constructed

4116+--- a new (), with the result that the code ended up with "case () of (a,b) -> ...".

4360+-section "Prefetch"

4361+- {Prefetch operations: Note how every prefetch operation has a name

4362+- with the pattern prefetch*N#, where N is either 0,1,2, or 3.

4363+-

4364+- This suffix number, N, is the "locality level" of the prefetch, following the

4365+- convention in GCC and other compilers.

4366+- Higher locality numbers correspond to the memory being loaded in more

4367+- levels of the cpu cache, and being retained after initial use. The naming

4368+- convention follows the naming convention of the prefetch intrinsic found

4369+- in the GCC and Clang C compilers.

4370+-

4371+- On the LLVM backend, prefetch*N# uses the LLVM prefetch intrinsic

4372+- with locality level N. The code generated by LLVM is target architecture

4373+- dependent, but should agree with the GHC NCG on x86 systems.

4374+-

4375+- On the Sparc and PPC native backends, prefetch*N is a No-Op.

4376+-

4377+- On the x86 NCG, N=0 will generate prefetchNTA,

4378+- N=1 generates prefetcht2, N=2 generates prefetcht1, and

4379+- N=3 generates prefetcht0.

4380+-

4381+- For streaming workloads, the prefetch*0 operations are recommended.

4382+- For workloads which do many reads or writes to a memory location in a short period of time,

4383+- prefetch*3 operations are recommended.

4384+-

4385+- For further reading about prefetch and associated systems performance optimization,

4386+- the instruction set and optimization manuals by Intel and other CPU vendors are

4387+- excellent starting place.

4388+-

4389+-

4390+- The "Intel 64 and IA-32 Architectures Optimization Reference Manual" is

4391+- especially a helpful read, even if your software is meant for other CPU

4392+- architectures or vendor hardware. The manual can be found at

4393+- http://www.intel.com/content/www/us/en/architecture-and-technology/64-ia-32-architectures-optimization-manual.html .

4394+-

4395+- The {\tt prefetch*} family of operations has the order of operations

4396+- determined by passing around the {\tt State#} token.

4397+-

4398+- To get a "pure" version of these operations, use {\tt inlinePerformIO} which is quite safe in this context.

4399+-

4400+- It is important to note that while the prefetch operations will never change the

4401+- answer to a pure computation, They CAN change the memory locations resident

4402+- in a CPU cache and that may change the performance and timing characteristics

4403+- of an application. The prefetch operations are marked has_side_effects=True

4404+- to reflect that these operations have side effects with respect to the runtime

4405+- performance characteristics of the resulting code. Additionally, if the prefetchValue

4406+- operations did not have this attribute, GHC does a float out transformation that

4407+- results in a let/app violation, at least with the current design.

4880++-- This information is used solely when producing documentation; it is

4881++-- otherwise ignored. The description is optional.

4882++--

4883++-- The format of each primop entry is as follows:

4884++--

4885++-- primop internal-name "name-in-program-text" type category {description} attributes

4886++

4887++-- The default attribute values which apply if you don't specify

4889++-- text between curly brackets. This is a kludge to enable

4890++-- processors of this file to easily get hold of simple info

4891++-- (eg, out_of_line), whilst avoiding parsing complex expressions

4892++-- needed for strictness info.

4893++--

4894++-- type refers to the general category of the primop. Valid settings include,

4895++--

4896++-- * Compare: A comparison operation of the shape a -> a -> Int#

4897++-- * Monadic: A unary operation of shape a -> a

4902++-- The vector attribute is rather special. It takes a list of 3-tuples, each of

4903++-- which is of the form <ELEM_TYPE,SCALAR_TYPE,LENGTH>. ELEM_TYPE is the type of

4904++-- the elements in the vector; LENGTH is the length of the vector; and

4905++-- SCALAR_TYPE is the scalar type used to inject to/project from vector

4906++-- element. Note that ELEM_TYPE and SCALAR_TYPE are not the same; for example,

4910++-- When a primtype or primop has a vector attribute, it is instantiated at each

4911++-- 3-tuple in the list of 3-tuples. That is, the vector attribute allows us to

4913++-- keywords: VECTOR, SCALAR, and VECTUPLE. These keywords are expanded to types

4914++-- derived from the 3-tuple. For the 3-tuple <Int64,INT64,2>, VECTOR expands to

4915++-- Int64X2#, SCALAR expands to INT64, and VECTUPLE expands to (# INT64, INT64

4938++section "The word size story."

4939++ {Haskell98 specifies that signed integers (type {\tt Int})

4940++ must contain at least 30 bits. GHC always implements {\tt

4941++ Int} using the primitive type {\tt Int\#}, whose size equals

4942++ the {\tt MachDeps.h} constant {\tt WORD\_SIZE\_IN\_BITS}.

4943++ This is normally set based on the {\tt config.h} parameter

4944++ {\tt SIZEOF\_HSWORD}, i.e., 32 bits on 32-bit machines, 64

4945++ bits on 64-bit machines. However, it can also be explicitly

4946++ set to a smaller number, e.g., 31 bits, to allow the

4947++ possibility of using tag bits. Currently GHC itself has only

4948++ 32-bit and 64-bit variants, but 30 or 31-bit code can be

4949++ exported as an external core file for use in other back ends.

4950++

4951++ GHC also implements a primitive unsigned integer type {\tt

4952++ Word\#} which always has the same number of bits as {\tt

4953++ Int\#}.

4954++

4955++ In addition, GHC supports families of explicit-sized integers

4956++ and words at 8, 16, 32, and 64 bits, with the usual

4957++ arithmetic operations, comparisons, and a range of

4958++ conversions. The 8-bit and 16-bit sizes are always

4959++ represented as {\tt Int\#} and {\tt Word\#}, and the

4960++ operations implemented in terms of the the primops on these

4961++ types, with suitable range restrictions on the results (using

4962++ the {\tt narrow$n$Int\#} and {\tt narrow$n$Word\#} families

4963++ of primops. The 32-bit sizes are represented using {\tt

4964++ Int\#} and {\tt Word\#} when {\tt WORD\_SIZE\_IN\_BITS}

4965++ $\geq$ 32; otherwise, these are represented using distinct

4966++ primitive types {\tt Int32\#} and {\tt Word32\#}. These (when

4967++ needed) have a complete set of corresponding operations;

4968++ however, nearly all of these are implemented as external C

4969++ functions rather than as primops. Exactly the same story

4970++ applies to the 64-bit sizes. All of these details are hidden

4971++ under the {\tt PrelInt} and {\tt PrelWord} modules, which use

4972++ {\tt \#if}-defs to invoke the appropriate types and

4973++ operators.

4974++

4975++ Word size also matters for the families of primops for

4976++ indexing/reading/writing fixed-size quantities at offsets

4977++ from an array base, address, or foreign pointer. Here, a

4978++ slightly different approach is taken. The names of these

4979++ primops are fixed, but their {\it types} vary according to

4980++ the value of {\tt WORD\_SIZE\_IN\_BITS}. For example, if word

4981++ size is at least 32 bits then an operator like

4982++ \texttt{indexInt32Array\#} has type {\tt ByteArray\# -> Int\#

4983++ -> Int\#}; otherwise it has type {\tt ByteArray\# -> Int\# ->

4984++ Int32\#}. This approach confines the necessary {\tt

4985++ \#if}-defs to this file; no conditional compilation is needed

4986++ in the files that expose these primops.

4987++

4988++ Finally, there are strongly deprecated primops for coercing

4989++ between {\tt Addr\#}, the primitive type of machine

4990++ addresses, and {\tt Int\#}. These are pretty bogus anyway,

4991++ but will work on existing 32-bit and 64-bit GHC targets; they

4992++ are completely bogus when tag bits are used in {\tt Int\#},

4993++ so are not available in this case. }

5063++ On a 32-bit platform, the recommended implementation is to do a

5064++ 32 x 32 -> 64 signed multiply, and subtract result[63:32] from

5065++ (result[31] >>signed 31). If this is zero, meaning that the

5067++ overflow can occur.

5068++

5069++ On a 64-bit platform it is not always possible to

5772++section "Small Arrays"

5773++

5774++ {Operations on {\tt SmallArray\#}. A {\tt SmallArray\#} works

5775++ just like an {\tt Array\#}, but with different space use and

5776++ performance characteristics (that are often useful with small

5777++ arrays). The {\tt SmallArray\#} and {\tt SmallMutableArray#}

5778++ lack a `card table'. The purpose of a card table is to avoid

5779++ having to scan every element of the array on each GC by

5780++ keeping track of which elements have changed since the last GC

5781++ and only scanning those that have changed. So the consequence

5782++ of there being no card table is that the representation is

5783++ somewhat smaller and the writes are somewhat faster (because

5784++ the card table does not need to be updated). The disadvantage

5785++ of course is that for a {\tt SmallMutableArray#} the whole

5786++ array has to be scanned on each GC. Thus it is best suited for

5787++ use cases where the mutable array is not long lived, e.g.

5788++ where a mutable array is initialised quickly and then frozen

5789++ to become an immutable {\tt SmallArray\#}.

7505++--

7506++-- reallyUnsafePtrEquality# can't actually fail, per se, but we mark it can_fail

7507++-- anyway. Until 5a9a1738023a, GHC considered primops okay for speculation only

7508++-- when their arguments were known to be forced. This was unnecessarily

7509++-- conservative, but it prevented reallyUnsafePtrEquality# from floating out of

7510++-- places where its arguments were known to be forced. Unfortunately, GHC could

7511++-- sometimes lose track of whether those arguments were forced, leading to let/app

7512++-- invariant failures (see Trac 13027 and the discussion in Trac 11444). Now that

7513++-- ok_for_speculation skips over lifted arguments, we need to explicitly prevent

7514++-- reallyUnsafePtrEquality# from floating out. The reasons are closely related

7515++-- to those described in Note [dataToTag#], although the consequences are less

7516++-- severe. Imagine if we had

7517++--

7518++-- \x y . case x of x'

7519++-- DEFAULT ->

7520++-- case y of y'

7521++-- DEFAULT ->

7522++-- let eq = reallyUnsafePtrEquality# x' y'

7523++-- in ...

7524++--

7525++-- If the let floats out, we'll get

7526++--

7527++-- \x y . let eq = reallyUnsafePtrEquality# x y

7528++-- in case x of ...

7529++--

7530++-- The trouble is that pointer equality between thunks is very different

7531++-- from pointer equality between the values those thunks reduce to, and the latter

7532++-- is typically much more precise.

7584++{- Note [dataToTag#]

7585++~~~~~~~~~~~~~~~~~~~~

7586++The dataToTag# primop should always be applied to an evaluated argument.

7587++The way to ensure this is to invoke it via the 'getTag' wrapper in GHC.Base:

7588++ getTag :: a -> Int#

7589++ getTag !x = dataToTag# x

7590++

7591++But now consider

7592++ \z. case x of y -> let v = dataToTag# y in ...

7593++

7594++To improve floating, the FloatOut pass (deliberately) does a

7595++binder-swap on the case, to give

7596++ \z. case x of y -> let v = dataToTag# x in ...

7597++

7598++Now FloatOut might float that v-binding outside the \z. But that is

7599++bad because that might mean x gest evaluated much too early! (CorePrep

7600++adds an eval to a dataToTag# call, to ensure that the argument really is

7601++evaluated; see CorePrep Note [dataToTag magic].)

7602++

7603++Solution: make DataToTag into a can_fail primop. That will stop it floating

7604++(see Note [PrimOp can_fail and has_side_effects] in PrimOp). It's a bit of

7605++a hack but never mind.

7729++pseudoop "unsafeCoerce#"

7730++ a -> b

7731++ { The function {\tt unsafeCoerce\#} allows you to side-step the typechecker entirely. That

7732++ is, it allows you to coerce any type into any other type. If you use this function,

7733++ you had better get it right, otherwise segmentation faults await. It is generally

7734++ used when you want to write a program that you know is well-typed, but where Haskell's

7735++ type system is not expressive enough to prove that it is well typed.

7736++

7737++ The following uses of {\tt unsafeCoerce\#} are supposed to work (i.e. not lead to

7738++ spurious compile-time or run-time crashes):

7739++

7740++ * Casting any lifted type to {\tt Any}

7741++

7742++ * Casting {\tt Any} back to the real type

7743++

7744++ * Casting an unboxed type to another unboxed type of the same size.

7745++ (Casting between floating-point and integral types does not work.

7746++ See the {\tt GHC.Float} module for functions to do work.)

7747++

7748++ * Casting between two types that have the same runtime representation. One case is when

7749++ the two types differ only in "phantom" type parameters, for example

7750++ {\tt Ptr Int} to {\tt Ptr Float}, or {\tt [Int]} to {\tt [Float]} when the list is

7751++ known to be empty. Also, a {\tt newtype} of a type {\tt T} has the same representation

7752++ at runtime as {\tt T}.

7753++

7754++ Other uses of {\tt unsafeCoerce\#} are undefined. In particular, you should not use

7755++ {\tt unsafeCoerce\#} to cast a T to an algebraic data type D, unless T is also

7756++ an algebraic data type. For example, do not cast {\tt Int->Int} to {\tt Bool}, even if

7757++ you later cast that {\tt Bool} back to {\tt Int->Int} before applying it. The reasons

7758++ have to do with GHC's internal representation details (for the cognoscenti, data values

7759++ can be entered but function closures cannot). If you want a safe type to cast things

7760++ to, use {\tt Any}, which is not an algebraic data type.

7761++

7762++ }

7763++

7764++-- NB. It is tempting to think that casting a value to a type that it doesn't have is safe

7765++-- as long as you don't "do anything" with the value in its cast form, such as seq on it. This

7766++-- isn't the case: the compiler can insert seqs itself, and if these happen at the wrong type,

7767++-- Bad Things Might Happen. See bug #1616: in this case we cast a function of type (a,b) -> (a,b)

7768++-- to () -> () and back again. The strictness analyser saw that the function was strict, but

7769++-- the wrapper had type () -> (), and hence the wrapper de-constructed the (), the worker re-constructed

8014++section "Prefetch"

8015++ {Prefetch operations: Note how every prefetch operation has a name

8016++ with the pattern prefetch*N#, where N is either 0,1,2, or 3.

8017++

8018++ This suffix number, N, is the "locality level" of the prefetch, following the

8019++ convention in GCC and other compilers.

8020++ Higher locality numbers correspond to the memory being loaded in more

8021++ levels of the cpu cache, and being retained after initial use. The naming

8022++ convention follows the naming convention of the prefetch intrinsic found

8023++ in the GCC and Clang C compilers.

8024++

8025++ On the LLVM backend, prefetch*N# uses the LLVM prefetch intrinsic

8026++ with locality level N. The code generated by LLVM is target architecture

8027++ dependent, but should agree with the GHC NCG on x86 systems.

8028++

8029++ On the Sparc and PPC native backends, prefetch*N is a No-Op.

8030++

8031++ On the x86 NCG, N=0 will generate prefetchNTA,

8032++ N=1 generates prefetcht2, N=2 generates prefetcht1, and

8033++ N=3 generates prefetcht0.

8034++

8035++ For streaming workloads, the prefetch*0 operations are recommended.

8036++ For workloads which do many reads or writes to a memory location in a short period of time,

8037++ prefetch*3 operations are recommended.

8038++

8039++ For further reading about prefetch and associated systems performance optimization,

8040++ the instruction set and optimization manuals by Intel and other CPU vendors are

8041++ excellent starting place.

8042++

8043++

8044++ The "Intel 64 and IA-32 Architectures Optimization Reference Manual" is

8045++ especially a helpful read, even if your software is meant for other CPU

8046++ architectures or vendor hardware. The manual can be found at

8047++ http://www.intel.com/content/www/us/en/architecture-and-technology/64-ia-32-architectures-optimization-manual.html .

8048++

8049++ The {\tt prefetch*} family of operations has the order of operations

8050++ determined by passing around the {\tt State#} token.

8051++

8052++ To get a "pure" version of these operations, use {\tt inlinePerformIO} which is quite safe in this context.

8053++

8054++ It is important to note that while the prefetch operations will never change the

8055++ answer to a pure computation, They CAN change the memory locations resident

8056++ in a CPU cache and that may change the performance and timing characteristics

8057++ of an application. The prefetch operations are marked has_side_effects=True

8058++ to reflect that these operations have side effects with respect to the runtime

8059++ performance characteristics of the resulting code. Additionally, if the prefetchValue

8060++ operations did not have this attribute, GHC does a float out transformation that

8061++ results in a let/app violation, at least with the current design.

140+- compiling Template Haskell, by spawning a separate delegate (so

141+- called runner on the javascript vm) and evaluating the splices

142+- there.

143+- .

144+- iserv can also be used in combination with cross compilation. For

146+- host (as it is running on the host). @cabal install -flibrary

147+- -fproxy@ will yield the proxy.

148+- .

149+- Using the cabal for the target @arch-platform-target-cabal install

150+- -flibrary@ will build the required library that contains the ffi

151+- @startSlave@ function, which needs to be invoked on the target

152+- (e.g. in an iOS application) to start the remote iserv slave.

153+- .

154+- calling the GHC cross compiler with @-fexternal-interpreter

155+- -pgmi=$HOME/.cabal/bin/iserv-proxy -opti\<ip address\> -opti\<port\>@

156+- will cause it to compile Template Haskell via the remote at \<ip address\>.

163+- > iserv $ arch-platform-target-cabal install -flibrary

760++Synopsis: iserv allows GHC to delegate Tempalte Haskell computations

761++Description:

762++ This is a very simple remote runner for iserv, to be used together

763++ with iserv-proxy. The foundamental idea is that this this wrapper

764++ starts running libiserv on a given port to which iserv-proxy will

765++ then connect.
