Merge pull request #205 from myegorov/untar-anywhere Replace absolute path in `bin/mlton` script with relative path and use `./build/lib/mlton` rather than `./build/lib`. This makes it possible to use the `./build` contents for installation and allows an installation to be relocated. Compare: https://github.com/MLton/mlton/compare/8267aa5794e6...c7ec0d6f7253 |

mlton/atoms/prim.fun M mlton/atoms/prim.sig M mlton/backend/ssa-to-rssa.fun M mlton/ssa/ssa-tree2.fun Log Message: ----------- Add `Array_uninit: 'a array * SeqInt.int -> unit` primitive The Array_uninit primitive sets all objptrs in the element at the given index to a bogus non-objptr value (0wx1). One motivation for this primitive is to support space-efficient polymorphic resizeable arrays. When shrinking a resizeable array, we would like to "NULL" out the elements that are no longer part of the logical array, in order to avoid a (logical) space leak.

This can be used to skip a bulk-Array_uninit loop when it is known that the Array_uninit operations would be nops. The primitive is translated to a constant by toRssa. It would be possible to introduce SSA and SSA2 optimizations that simplified Array_uninitIsNop and Array_uninit when it is clear that the array will never have objptrs in the elements. In particular, while an `(int64 * int64) array` (in SSA) might become an `int64 array` (due to Useless), the reverse can never happen. Similarly, while an `((int64 * int64)) array` (in SSA2) might become an `(int64 * int64) array` (due to DeepFlatten), the reverse can never happen. Also, RSSA shrink does not seem to simplify the switch {test = 0x0: Word32, default = None, cases = ((0x0, L_1277), (0x1, L_1276))} that results from replacing Array_uninitIsNop with a constant.

A related `Array_toArray` primitive updates the header of an `Array_allocRaw` primitive to reveal the objptrs. Between the allocation and the cast, all elements of the array must be uninitialized (setting all objptrs in elements to a bogus non-objptr value (0wx1)). One motiviation for this primitive is that, in a parallel setting, the uninitialization of an array can be a sequential bottleneck. The `Array_allocRaw` is a constant time operation and the subsequent `Array_uninit` operations can be performed in parallel. Note that it is not safe to write non-bogus objptrs into a raw array. Because the raw array's header indicates that the array has no objptrs, non-bogus objptrs written to the array will not be traced or updated during a garbage collection. In the future, we may consider eliminating `Array_alloc` (the non-raw array allocation) and moving the uninitialization loop from the runtime to SML. To do so, though, we should ensure that arrays that do not need uninitialization are optimized early in the optimization pipeline.

However, if "small" arrays were globalized, then an `Array_allocRaw[t] (l)` would be globalized as `Array_alloc[t] (l)` and the `Array_toArray` (that casts the raw array to a normal array) would be dropped. Now, the `Array` abstract value tracks whether the array is raw or normal, which is used to generate either `Array_allocRaw` or `Array_alloc` if the array is globalized. Also, `Array_toArray` creates the destination `Array` abstract value with `Birth.unknown()`, which prohibits globalization.

pull request #204 from myegorov/share-zero-vec SSA optimization to share zero-length vectors >From be8c5f5: > Replace the use of Array_array0Const primitive in the Basis Library implementation with a (nullary) Vector_vector primitive. > The original motivation for the Array_array0Const primitive was to share the heap space required for zero-length vectors among all vectors (of a given type). It was claimed that this optimization is important, e.g., in a self-compile, where vectors are used for lots of syntax tree elements and many of those vectors are empty. See: http://www.mlton.org/pipermail/mlton-devel/2002-February/021523.html > Curiously, the full effect of this optimization has been missing for quite some time (perhaps since the port of ConstantPropagation to the SSA IL). While ConstantPropagation has "globalized" the nullary application of the `Array_array0Const` primitive, it also simultaneously transformed it to an application of the `Array_uninit` (previously, the `Array_array`) primitive to the zero constant. The hash-consing of globals, meant to create exactly one global for each distinct constant, treats `Array_uninit` primitives as unequal (appropriately, since `Array_uninit` allocates an array with identity (though the identity may be supressed by a subsequent `Array_toVector`)), hence each distinct `Array_array0Const` primitive in the program remained as distinct globals. The limited amount of inlining prior to ConstantPropagation meant that there were typically fewer than a dozen "copies" of the same empty vector in a program for a given type. > As a "functional" primitive, a nullary `Vector_vector` is globalized by ClosureConvert, but is further recognized by ConstantPropagation and hash-consed into a unique instance for each type. However, a single, shared, global `Vector_vector ()` inhibits the coercion-based optimizations of `Useless`. For example, consider the following program: val n = valOf (Int.fromString (hd (CommandLine.arguments ()))) val v1 = Vector.tabulate (n, fn i => let val w = Word16.fromInt i in (w - 0wx1, w, w + 0wx1 + w) end) val v2 = Vector.map (fn (w1, w2, w3) => (w1, 0wx2 * w2, 0wx3 * w3)) v1 val v3 = VectorSlice.vector (VectorSlice.slice (v1, 1, SOME (n - 2))) val ans1 = Vector.foldl (fn ((w1,w2,w3),w) => w + w1 + w2 + w3) 0wx0 v1 val ans2 = Vector.foldl (fn ((_,w2,_),w) => w + w2) 0wx0 v2 val ans3 = Vector.foldl (fn ((_,w2,_),w) => w + w2) 0wx0 v3 val _ = print (concat ["ans1 = ", Word16.toString ans1, " ", "ans2 = ", Word16.toString ans2, " ", "ans3 = ", Word16.toString ans3, "\n"]) We would like `v2` and `v3` to be optimized from `(word16 * word16 * word16) vector` to `word16 vector` because only the 2nd component of the elements is needed to compute the answer. With `Array_array0Const`, each distinct occurrence of `Array_array0Const((word16 * word16 * word16))` arising from polyvariance and inlining remained a distinct `Array_uninit((word16 * word16 * word16)) (0x0)` global, which resulted in distinct occurrences for the `val v1 = Vector.tabulate ...` and for the `val v2 = Vector.map ...`. The latter could be optimized to `Array_uninit(word16) (0x0)` by `Useless`, because its result only flows to places requiring the 2nd component of the elements. With `Vector_vector ()`, the distinct occurrences of `Vector_vector((word16 * word16 * word16)) ()` arising from polyvariance are globalized during `ClosureConvert`, those global references may be further duplicated by inlining, but the distinct occurrences of `Vector_vector((word16 * word16 * word16)) ()` are merged to a single occurrence. Because this result flows to places requiring all three components of the elements, it remains `Vector_vector((word16 * word16 * word16)) ()` after `Useless`. Furthermore, because one cannot (in constant time) coerce a `(word16 * word16 * word16) vector` to a `word16 vector`, the `v2` value remains of type `(word16 * word16 * word16) vector`. One option would be to drop the 0-element vector "optimization" entirely. This costs some space (no sharing of empty vectors) and some time (allocation and garbage collection of empty vectors). Another option would be to reinstate the `Array_array0Const` primitive and associated `ConstantPropagation` treatment. But, the semantics and purpose of `Array_array0Const` was poorly understood, resulting in this break. This pull request pursues a different approach: perform the 0-element vector "optimization" as a separate optimization, after `ConstantPropagation` and `Useless`. A trivial static analysis is used to match `val v: t vector = Array_toVector(t) (a)` with corresponding `val a: array = Array_uninit(t) (l)` and the later are expanded to `val a: t array = if 0 = l then zeroArr_[t] else Array_uninit(t) (l)` with a single global `val zeroArr_[t] = Array_uninit(t) (0)~ created for each distinct type (after coercion-based optimizations). One disadvantage of this approach, compared to the `Vector_vector(t) ()` approach, is that `Array_toVector` is applied each time a vector is created, even if it is being applied to the `zeroArr_[t]` zero-length array. (Although, this was the behavior of the `Array_array0Const` approach.) This updates the object header each time, whereas the `Vector_vector(t) ()` approach would have updated the object header once, when the global was created, and the `zeroVec_[t]` global and the `Array_toVector` result would flow to the join point. It would be possible to properly share zero-length vectors, but doing so is a more sophisticated analysis and transformation, because there can be arbitrary code between the `val a: t array = Array_uninit(t) (l)` and the corresponding `val v: v vector = Array_toVector(t) (a)`, although, in practice, nothing happens when a zero-length vector is created. It may be best to pursue a more general "array to vector" optimization that transforms creations of static-length vectors (e.g., all the `Vector.new<N>` functions) into `Vector_vector` primitives (some of which could be globalized).

There is a note in common-subexp.fun regarding this canonicalizing of commutative arguments: fun canon2 () = let val a0 = arg 0 val a1 = arg 1 in (* What we really want is a total orderning on * variables. Since we don't have one, we just use * the total ordering on hashes, which means that * we may miss a few cse's but we won't be wrong. *) if Var.hash a0 <= Var.hash a1 then (a0, a1) else (a1, a0) end Note that the only cse-s that a lack of a total ordering would miss are "a + b" and "b + a", where the variables "a" and "b" both had the same hash. On the other hand, the order of arguments to commutative arithmetic arguments is sensitive to variable hashes and variable hashes are created by an unseeded pseudo-random number generator. This pseudo-random number generator is used create hashes for all classes of identifiers, so while variable hashes are deterministic, they are sensitive to the number of identifiers created before the variable is created. Hence, the creation of more or less identifiers (for example, when resuming compilation from a saved .sxml program) the assignment of hashes to variable identifiers, which might swap the arguments of commutative arithmetic primitives. Indeed, the only difference between the .ssa when compiling the original program and the .ssa when resuming compilation from a corresponding saved .sxml file is the order of some commutative arithmetic primitives. One would hope that the codegens would not be sensitive to the ordering of arguments in commutative arithmetic primitives. Indeed, the native codegens do some analysis to pick a "good" order in which to handle the arguments of commutative arithmetic primitives. However, when there isn't anything to break the tie when looking for a "good" order, the generated code follows the order of the arguments in the primitive. We've seen situations where a small code permutation, which results in the swapping of some commutative arithmetic primitive arguments leads to non-trivial run-time differences. This commit introduces four different canonicalization strategies for arguments to commutative arithmetic primitives. "ascHash" and "descHash" correspond to the strategies that put the arguments in order of ascending or descending variable hashes, respectively. "ascIndex" and "descIndex" correspond to strategies that put the arguments in order of ascending or descending variable indices, respectively. Variable indices are set according to a counter and a variable's index is set when it's defining occurrence is encountered during the walk of the dominator tree. This doesn't guarantee that a variable's index is always the same under different compiles; a variable's index is sensitive to the number of variables set before it, which will depend upon the particular program and previous program transformations. However, this indexing strategy does have the advantage that the relative order of two variables will always correspond to the relative scope of the two variables, which will tend to be stable across compiles, so long as the variables in question are not the subject of a serious optimization.

The commit nicely factored out the code to setup runtime constants and ran it before initiating compilation of .sml/.mlb or .sxml programs. What is not apparent from the code in `main/compile.fun` is that `LookupConstant.load` implicitly initializes some other constants. In particular, it initializes the `MLton_FFI_numExports` constant, which in turn, is set by `Ffi.numExports ()`, which is itself a derived value of the program being compiled (essentially, counting the number of `_export` expressions in the program). The laziness of CoreML constants is precisely to support this derived constant (and, potentially, others that might be a property of the program being compiled, though there are no other such constants at the present time). The fix is simple: perform `setupConstants` after elaboration. Technically, the `defunctorize` pass that converts the CoreML program to an XML program will have forced the constants (and performed the `LookupConstant.load`), but that is sufficiently late that `Ffi.numExports ()` will return a correct value. It is still necessary to perform `setupConstants` to propagate values for the runtime constants.

Nicely, this regular expression works with both error messages of the form: Error: z.sml 1.5. and of the form: Error: z.sml 1.5-1.11. However, one problem is that emacs interprets an end-line/end-column as inclusive of the range to be highlighted, rather then being one character beyond the range to be highlighted.

Thus, the following program: val i = case 0 of 0 => true | 1 => ignore 1 | _ => false yields the error message: Error: z.sml 4.12-5.5.

In addition to being somewhat more uniform, this fixes two minor bugs in MLton that erroneously accepted: fun op= z = z and signature S = sig val = : unit -> unit end In the first case, although `val op= = fn x => x` and `val rec op= = fn x => x` (and, generally, any use of `=` in patterns) were correctly reported as errors, the function name in a fun declaration was only checked against the special identifiers; therefore, an `=` identifier was allowed to be bound. In the second case, names in val descriptions were only checked against the special identifiers; therefore an `=` identifier was allowed to be specified. Note that the Definition states "The identifier = may not be re-bound". Arguably, the Definition allows `=` to be specified in a signature. However, the use of a signature that specifies `=` in a functor argument would constitute a binding of `=` (although, it would not be possible to apply the functor, as it would not be possible to define a structure that binds `=` so as to match the signature). Hence, we choose to treat `=` as a special identifier and exclude it from specifications and definitions.

The parser uses the fine-grained identifier classes to properly define vid, longvid, tycon, longtycon, field, strid, longstrid, sigid, and fctid classes. This fixes a minor bug where MLton erroneously accepted symbolic identifiers for strid, sigid, and fctid and erroneously accepted symbolic identifiers before "." in long identifiers. This also further extends the treatment of `=` as a special identifier by allowing including `=` in the vid class and equating the con class with the vid class. Thus, the program: datatype t = = of unit does not give a parse error, but does give a "Special identifier cannot be redefined by datata: =." error. This almost allows `=` everywhere a vid is allowed. The exception is that a vidNoEquals class is used (as was previously) in atomic patterns. The issue is with val pat = exp and fun f apat apat ... apat = exp phrases, where an `=` in the pattern is difficult to distinguish from the `=` terminating the pattern(s). It would be possible to have a set of *NoEqual pattern productions that excluded the `=` vid, which would be used for these patterns appearing in declarations.

With suitable editor support (e.g., emacs compilation-error-regexp-alist), it is easy to visit one of the points to resolve the error.

Due to constraints, the same flexible type constructor can be identified by multiple paths. Consider the following program. structure S : sig structure T : sig datatype t = T end type u = T.t end = struct structure T = struct datatype t = T end type u = int end Previously, the following error messages were generated: Error: z.sml 2.4-8.6.

When `u` is realized by `int`, it implies in the signature that `T.T` is (incorrectly) a constructor of the `int` type, but in the structure `T.T` is (correctly) a constructor of the `T.t` type. The choice of `u` as the candidate path to be realized for the flexible type constructor was due to `u` being the shortest path in the signature that identifies the flexible type constructor. Now, the following error message is generated: Error: z.sml 2.4-8.6. Type in structure disagrees with signature: u. structure: [u] defn at: z.sml 14.9-14.9 signature: [T.t] spec at: z.sml 7.12-7.12 This is due to changing the heuristic for choosing the candidate path to prefer a path to a `datatype` specification for a flexible type constructor that is a `datatype`. Unfortunately, it isn't currently possible to distinguish a replicating `datatype` specification from a non-replicating `datatype` specification. Hence, with the program: structure S : sig structure T : sig datatype t = T end datatype u = datatype T.t end = struct structure T = struct datatype t = T end type u = int end the path `u` is chosen as the candidate and the following error messages are generated: Error: z.sml 2.4-8.6.

mlton/elaborate/elaborate-core.fun Log Message: ----------- Update diagnostics for (recursive) function declarations The primary motivation is to minimize the use of the (confusing) "recursive use of function disagrees with its type" error message. In particular, it can be frustrating to add type information to a function declaration in the hopes of identifying the problematic recursive use, only to have the type information seemingly ignored. For example, consider the following program: fun f (): int = 13 | f (): bool = true fun g (x: int) = g true fun h x = (x + 1; h true) fun i x = j true and j y = y + 1 Previously, MLton generated the following error messages: Error: z.sml 2.18-2.21. Function clause with expression of different type. expression: [bool] previous: [int] in: fun f (): int = 13 | f (): bool = true Error: z.sml 4.5-4.5. Recursive use of function disagrees with its type. function type: [int] -> _ recursive use: [bool] -> _ in: fun g (x: int) = (g true) Error: z.sml 6.5-6.5. Recursive use of function disagrees with its type. function type: [int] -> _ recursive use: [bool] -> _ in: fun h x = (x + 1 ; h true) Error: z.sml 9.5-9.5. Recursive use of function disagrees with its type. function type: [int] -> _ recursive use: [bool] -> _ in: fun i x = (j true) and j y = (y + 1) Now, MLton generates the following error messages: Error: z.sml 2.11-2.14. Function clause with result constraint of different type. constraint: [bool] previous: [int] in: fun f (): int = 13 | f (): bool = true Error: z.sml 4.18-4.23. Function applied to incorrect argument. expects: [int] but got: [bool] in: g true Error: z.sml 6.5-6.5. Recursive use of function disagrees with its type: h. function type: [int] -> _ recursive use: [bool] -> _ in: fun h x = (x + 1 ; h true) Error: z.sml 9.5-9.5. Recursive use of function disagrees with its type: j. function type: [int] -> _ recursive use: [bool] -> _ in: fun i x = (j true) and j y = (y + 1) The second function exemplifies the typical case, where the type annotations on a function are used when entering the function into the environment, leading to type errors at the use site. This follows the heuristic that explicitly written information is more likely correct than implicitly inferred information. The third and fourth functions clarify that only explicit information in the function patterns/result-constraint are used when entering the function into the environment; in the absence of explicit information, the function is given a fresh unification variable when entered into the environment, which is unified with the type inferred for the function code.

Recursive use of function disagrees with function declaration type: g2. recursive use: _ -> [int] function type: _ -> [bool] in: fun f2 z = (if z <= 0 then 1 else ... lse else f2 (z - 1)) There is a bit of asymmetry, due to `g1` being constrained to the type `int -> int` by the `g1 (z - 1)` in the function body of `f1` and `f1` being constrained to the type `int -> int` by the function expression of `f1`, all before processing the function expression and binding of `g1`. Contrast with the handling of the `fun` version, which gives symmetric errors by delaying the unification of the function variables with their inferred function types until all functions have been processed. Now, MLton generates the following error messages: Error: z.sml 1.9-1.10. Recursive use of function disagrees with function expression type: f1. recursive use: _ -> [bool] function type: _ -> [int] in: val rec f1 = fn z => (if z <= 0 t ... lse else f1 (z - 1)) Error: z.sml 2.9-2.10.

myegorov/build-configure Initial support for `./configure` and Travis-CI. The `./configure` step will check for `mlton`, `mllex`, and `mlyacc` plus check for other standard tools and for GMP. The `--with-gmp-lib` and `--with-gmp-include` flags can be used to specify the location of GMP, if it is not natively found by the C compiler. A `--prefix` flag can be used to specify an install prefix. The C compiler found by the `./configure` step (e.g., specified by `CC` environment variable) will be used to build the runtime system and by the built `mlton` when building programs.

This was motivated by the observation that Poly/ML's string concatenation was significantly faster than MLton's; investigation showed that Poly/ML uses `memmove` to implement string concatenation, which out performs MLton's element-by-element construction for large strings. See the discussion thread at: https://sourceforge.net/p/mlton/mailman/mlton-user/thread/CAG%2BQnTcffmvXcpFv9rivvwdcsRXvUCorYVdEPmhjCE8EHEpOig%40mail.gmail.com/#msg35312358 Within the Basis Library implementation, the `Array_copy{Array,Vector}` primitives are only used for copies of more than 5 elements; this is to avoid the overhead of an FFI call for copies of few elements. Instrumenting the `GC_arrayCopy` function to record number of elements copied at each invocation shows that a self-compile makes 37074056 calls to `GC_arrayCopy` with the following statistics on number of elements copied: min 0 median 3 mean 7.767096 max 146120 histogram: count density cumulative 0 8138 0.0002195066 0.0002195066 1 1556411 0.0419811364 0.0422006430 2 8922853 0.2406764720 0.2828771149 3 9395704 0.2534307010 0.5363078159 4 7053342 0.1902500768 0.7265578927 (4,8] 4883067 0.1317111621 0.8582690548 (8,16] 1113094 0.0300235291 0.8882925839 (16,146120] 4141447 0.1117074161 1.0000000000 There is one potential missed optimization due to the use of `Array_copy{Array,Vector}` instead of an element-by-element copying loop. Analyses and transformations must ensure that the element type of the source and destination sequence are the same (unified) for uses of `Array_copy{Array,Vector}`, whereas the element type of the source need only be coercable to the element type of the destination for uses of `{Array,Vector}_sub` followed by `Array_update`. That is, the element-by-element copy loop has the opportunity to modify the element as it is copied (e.g., drop unused fields of a tuple), but an `Array_copy{Array,Vector}` cannot modify elements as they are copied.

Initial evaluation demonstrates some non-trivial performance gains, no non-trivial performance losses, and only minor code size increases. Refactor inlining, loop unswitching, and loop unrolling optimizations to consolidate sizing functions in SSA_TREE. Replace `-drop-pass <regex>` compile option with `-disable-pass <regex>` compile option and add `-enable-pass <regex>` compile option. Various XML, SXML, SSA, SSA2, and RSSA optimization passes are initialized with a default status, which can be overriden by `-{disable,enable}-pass`. In particular, it is now easy to add a work-in-progress (and potentially buggy) pass to the simplification pipeline with `execute=false` default status, to be selectively executed with `-enable-pass`. Currently, loopUnswitch and loopUnroll are disabled pending a more thorough evaluation. Compare: https://github.com/MLton/mlton/compare/89267b1d196a...6c18e44220a6 |

Extend that special case to record/tuple patterns of all variables or wilds, which is a common idiom, arising from any "#f" field selection expression or "val (x, _) = ..." declaration.

----------- Merge pull request #181 from MatthewFluet/nonexhaustive-and-redundant-diagnostics A number of improvements to the nonexhaustive and redundant pattern diagnostics. Highlights include: * Expand the set of MLB annotations. (047ea39, 3c26e39) * `nonexhaustiveBind`, `nonexhaustiveExnBind`, `redundantBind`: controls diagnostics for `val` declarations (which may raise Bind on failure). * `nonexhaustiveMatch`, `nonexhaustiveExnMatch`, `redundantMatch`: controls diagnostics for `case` expressions, `fn` expressions, and `fun` declarations (which may raise Match on failure). * `nonexhaustiveRaise`, `nonexhaustiveExnRaise`, `redundantRaise`: controls diagnostics for `handle` expressions (which implicitly re-raise on failure). Note that `nonexhaustiveRaise` and `nonexhaustiveExnRaise` default to `ignore`. The combination of `nonexhaustiveRaise warn` and `nonexhaustiveExnRaise ignore` can be useful for finding handlers that handle some, but not all, values of an exception variant. * Make a number of improvements to diagnostic messages: * Display nonexhaustive exception patterns as `_ : exn`, rather than `e`. (baded47) * Normalize nonexhaustive patterns by sorting (e.g., by ConApp name). (af45703) * Report complete enumeration of unhandled constants, rather than a single example. (0e8d639) * Report nonexhaustive patterns of record type as records, rather than as tuples. (e1d77ca, d4e59fc) Compare: https://github.com/MLton/mlton/compare/3a4546f49625...0978cd579e4a |

However, many variables bound in the main function are simply required as components to compute the "real" global that is used by the rest of the program. For example, consider a list literal that is lifted to a global; in the SSA and RSSA IRs, each tail is also bound as a global, but only the final cons is referenced elsewhere in the program. A simple walk over the non-main functions of the RSSA IR program identifies those variables used outside of the main function and only variables that are defined in the main function and used outside of the main function are allocated as globals; other variables can be allocated as Stack or Register as appropriate. On a self-compile, globals change from: PRIVATE CPointer globalCPointer [3]; PRIVATE Int8 globalInt8 [0]; PRIVATE Int16 globalInt16 [0]; PRIVATE Int32 globalInt32 [0]; PRIVATE Int64 globalInt64 [0]; PRIVATE Objptr globalObjptr [9157]; PRIVATE Real32 globalReal32 [7]; PRIVATE Real64 globalReal64 [9]; PRIVATE Word8 globalWord8 [0]; PRIVATE Word16 globalWord16 [377]; PRIVATE Word32 globalWord32 [524]; PRIVATE Word64 globalWord64 [625]; PRIVATE Pointer globalObjptrNonRoot [1]; to: PRIVATE CPointer globalCPointer [3]; PRIVATE Int8 globalInt8 [0]; PRIVATE Int16 globalInt16 [0]; PRIVATE Int32 globalInt32 [0]; PRIVATE Int64 globalInt64 [0]; PRIVATE Objptr globalObjptr [6180]; PRIVATE Real32 globalReal32 [7]; PRIVATE Real64 globalReal64 [9]; PRIVATE Word8 globalWord8 [0]; PRIVATE Word16 globalWord16 [80]; PRIVATE Word32 globalWord32 [4]; PRIVATE Word64 globalWord64 [73]; PRIVATE Pointer globalObjptrNonRoot [1]; This saves some code size and runtime space (since these globals are statically allocated). Furthermore, reducing the number of global objptrs saves some GC work, since each GC needs to iterate through all of the global objptrs. In general, heap space won't be saved, since (as described above) most variables in the main function that are not global are used to construct objects that are global objptrs, so the objects allocated in the main function are typically retained by their (global) containing object.

Now the containing statement or transfer, the containing block label, and the containing function name are appended to the error message (6bee991). * Add `-layout-width <n>` compile time expert option to control the target width for the pretty printer (d93db6f). * Make cosmetic improvements to SSA and SSA2 IR display: * Uses of global variables bound to small constants and conapps are commented with the corresponding value (50070b6). * Include loop forest, along with control-flow graph and dominator tree, for functions with `-keep dot` (58502c8, 19e385d). * Fix Ssa.PrePasses.breakCriticalEdges for codeMotion (4cfc92c). * Make cosmetic improvements to RSSA IR display (303e2cb). * Improve RSSA constant folding and copy propagation (36ec8ab) * Limit Machine IR Globals to variables used outside of the main function (c562d91).

Commit: e2873ffc947de34f9ad2ec2dfc2220183191835a https://github.com/MLton/mlton/commit/e2873ffc947de34f9ad2ec2dfc2220183191835a Author: Matthew Fluet <mat...@gm...> Date: 2017-04-15 (Sat, 15 Apr 2017) Changed paths: M runtime/gc/init.c Log Message: ----------- Improve handling of missing runtime option arguments Uniformly treat "--" as a missing argument; for most runtime options requiring an option, a "--" is flagged as an invalid int or float. However, for "gc-summary-file", it can be (typical) be opened as a file and may be incorrectly taken as the argument.
