The intended purpose of 136f3573c was to omit copying values returned via the ML stack on non-tail calls to `Cont` (normal return) and `Handle` (exceptional return) blocks and to omit copying a result returned from a `CCall` to a `CReturn` block; essentially, the receiving block is required to accept those arguments due to calling convention, but the argument may not be otherwise used, so the copies are extraneous. The implementation of 136f3573c simply omitted allocating a location (Machine IR stack slot or register (local)) for any unused argument of any block. The assumption was that only `Cont`, `Handle`, and `CReturn` blocks could have unused arguments; it was assumed that previous optimizations would eliminate any argument of a `Jump` block that was unused. However, with RedPRL, there is (at least one) `Jump` block with an unused argument; that argument is not assigned a location, so the `Option` exception is raised when trying to implement a `Goto` transfer that copies the actual operands to the formal arguments (and the corresponding formal argument doesn't exist). The fix is straight forward: only copy the actual arguments that correspond to formal arguments that are used; this is essentially the same filtering that is used to implement the prologue of `Cont` and `Handle` blocks. Closes MLton/mlton#305. Commit: 78fffc480aa56612b7deb3d187450fe1f3cabf45 https://github.com/MLton/mlton/commit/78fffc480aa56612b7deb3d187450fe1f3cabf45 Author: Matthew Fluet <mat...@gm...> Date: 2019-05-28 (Tue, 28 May 2019) Changed paths: M mlton/backend/backend.fun Log Message: ----------- Simplify code to generate prologue of `Cont` and `Handler` blocks f2b08b921 (Omit copying unused args of Cont and Handler blocks from stack) introduced code to check whether or not a `Cont` or `Handler` block argument was used by inspecting the `live` set. Then 136f3573c (Omit allocating registers for unused args of Cont, CReturn, and Handler blocks) introduced code to check whether or not a `Cont` or `Handler` block argument was assigned a location. However, `Cont` or `Handler` block argument is not assigned a location exactly when it is not a member of the `live` set. Hence, the original code to check whether or not a `Cont` or `Handler` block argument was used by inspecting the `live` set is redundant; the code to check whether or not a `Cont` or `Handler` block argument was assigned a location suffices.

Now, a chunk has the prototype `uintptr_t ChunkN(uinptr_t)`, where the argument is the index of the next block to execute and the result is the index of the next block to execute, so the trampoline looks like: nextChunk = nextChunks[nextBlock]; nextBlock = (*nextChunk)(nextBlock); In addition, the global `int returnToC`, used to signal the termination of a call to an exported SML function, is eliminated. Instead, the special block index `(uintptr_t)-1` is used to terminate the trampoline. One minor inefficiency is that the known destination chunk of a call cannot be exploited.

This is unnecessary (and does not work in the CMU MultiMLton project); in particular, it requires the c compiler to write the result to memory and, depending on the intervening code, to read the result from memory, although the result value is likely to have been returned via a register. Now, the `CReturn<ty>` variables are chunk local. They are marked `__attribute__ ((unused))` to suppress compiler warnings. Although it would be possible to examine the set of CCalls in the chunk (as is done to declare the FFI calls) and only generate variables that correspond to return types of called functions, even this does not suffice, because a CReturn block can ignore the result and the `CReturn<ty>` variable is unused.

Examples are Thread_switchTo and GC_collect (with signals). maySwitchThreadsTo indicates that the C function's return block may be switched to, in the sense that that block may be indicated by the return address on the top of a stack seen by a `maySwitchThreadsFrom` function. Examples are Thread_switchTo, GC_collect (with signals), GC_copyCurrent, and GC_saveWorld; note that these last two functions will always return and resume execution with the C function's return block (the ML thread is not switched by these functions), but explicit thread switching or world resumption will also begin execution at the C functions' return block. Note that maySwitchThreadsFrom implies maySwitchThreadsTo. This change is in preparation for a change to the C and LLVM codegens to treat `maySwitchThreadsTo` as the indicator of an entry, rather than `mayGC`.

However, it is unnecessary for `mayGC=true` but `maySwitchThreadsTo=false` to be entries. Furthermore, it can lead to C compiler warnings, due to the following: ChunkSwitch (0) ... case 5: goto L_45; ... EndChunkSwitch L_44: S(Word64, 56) = /* L_45 */ 5; Push (64); FlushFrontier (); FlushStackTop (); CReturnP = GC_sequenceAllocate (GCState, (Word64)(0x0ull), (Word64)(0x21ull), (Word64)(0x1Bull)); CacheFrontier (); CacheStackTop (); goto L_45; L_45: Push (-64); S(Objptr, 56) = CReturnP; W64_0 = (Word64)(0x0ull); goto loop_6; `GC_arrayAllocate` has `mayGC=true` and `maySwitchThreadsTo=false`. Making `L_45` an entry block makes it appear that control can enter the chunk and transfer to `L_45`, without assigning `CReturnP`. Now, `L_45` is not treated as an entry block and the only path to `L_45` is from the `GC_arrayAllocate` call.

One purpose is to serve as the unique index for "entry" blocks in the C and LLVM codegens. `Func` blocks are "entry" blocks and, previously, were assigned indices after all of the frame indices of existing blocks. This has the disadvantage of making the `Func` entry indices disjoint from the other block indices, possibly inhibiting turning the chunk entry switch into a jump table. Moreover, with 6bc091d, the set of entry blocks for a chunk was reduced for `CReturn` blocks from those that have `mayGC=true` to those that have `maySwitchThreadsTo=true`. This further fragments the chunk entry switch. To facilitate making the chunk entry switch a dense switch, `Func` blocks are assigned frames. This frame is never used by the runtime system, since a `Func` label is never the stack top. (Note: `Handler` blocks are also assigned frames, and this frame is also never used by the runtime system, since a `Handler` label is never the stack top. On the other hand, the "size" of a `Handler` frame is used to pop the stack.) Hence, the frame is assigned the empty list of live offsets and a size of 0. This means that, for the native codegen, all `Func` blocks will share the same frame layout and we only "waste" one entry in the `frameLayouts` array (and, potentially, one entry in the `frameOffsets` array, if the empty list of offsets is not otherwise created). For the C and LLVM codegens, we will create a distinct entry in the `frameLayouts` array for each `Func` block; since there are an order of magnitude more `Cont`, `Handler`, and `CReturn` blocks than `Func` blocks, this should not be significant in code size.

This pass simply shuffles the list of functions within the program and shuffles the vector of blocks within a function. The motivation of RSSAShuffle is that `-chunkify coalesce<n>` has a (small) dependency on the order of functions and blocks.

While this may have been helpful for compile time, due to reducing the number of .c files generated, with `-chunk-batch <n>`, small chunks will be placed in the same .c file.

This allowed checked arithmetic operations to be encoded as an unchecked arithmetic operation followed by an overflow-checking operation followed by an `if` that either raises the `Overflow` exception or returns the arithmetic result. However, the overflow primitives (that implicitly raise a special `PrimOverflow` exception in the early ILs and are used in `Arith` transfers in the late ILs) remained in the compiler. This pull request removes the old overflow primitives entirely, along with the special-case code required to support them.

However, no `EnsuresBytesFree` operand was created for the C call; instead, a constant 0 operand was being used for the `bytesRequested` argument. During the `insertLimitChecks` pass, a C call with `ensuresBytesFree = true` is expected to have an `EnsuresBytesFree` operand that can be replaced by the amount of heap space required by the C call return block. Failing to pass the appropriate `bytesRequested` allows the garbage collection to shrink the heap and fail to ensure that the necessary heap space is available. The `gc-collect2.sml` regression test demonstrates a program that performs a large sequence of allocations immediately after `MLton.GC.collect()`. When executed with a `live-ratio` near 1.0, the explicitly requested garbage collection leaves the heap too small to handle the subsequent allocations and a segmentation fault occurs. Adjusting the translation of `GC_collect` to include an `EnsuresBytesFree` operand fixes the bug. However, the inconsistency between `ensuresBytesFree = true` and the created operands suggested another more robust solution: eliminate the `Rssa.Operand.EnsuresBytesFree` and change the `ensuresBytesFree` flag of `CFunction.Kind.Runtime` from `bool` to `int option`. Like the `bytesNeeded` flag of `CFunction.Kind.Runtime`, the `int option` indicates the index of the argument that specifies a number of bytes that must be free when the C function returns.

Matthew Fluet <mat...@gm...> Date: 2019-02-16 (Sat, 16 Feb 2019) Changed paths: M mlton/atoms/id.fun M mlton/atoms/id.sig Log Message: ----------- Implement `ID.parse: t Parse.t` and related functions Parsing of identifiers is complicated, even when restricted to well-formed IL programs with single defs of each variable. Each def and use of the same variable in a printed IL program must be mapped to the same ID object. To handle this, a hash table mapping strings to ID objects is maintained. Some IDs are special (e.g., the Tycon corresponding to `bool`), because there is a particular (global) ID object for that identifier. To handle this, `val parseReset: {prims: t vector} -> unit` is used to remove all entries from the hash table and insert a number of primitive identifiers into the hash table (according to the identifier's `toString`). Non-special IDs are printed with a uniquifying suffix (e.g., `x_123`), but if that identifier is parsed and then printed again, we do not wish to add another uniquifying suffix identifier is printed (e.g., `x_123_456`). To handle this, parsing strips the uniquifying suffix when creating the ID object (using `newString`). A more sophisticated implementation would strip the uniquifying suffix, create the ID object with an originalName and a printName, and update the UniqueString table based on the suffix. Finally, it is sometimes useful to handle tokens that could appear where an identifier could occur, but should not be taken as an identifier. (For example, in the SSA2 IL, an ObjectCon is either a Con identifier, "tuple", or "sequence".) To handle this, `val parseAs: (string * 'a) vector * (t -> 'a) -> 'a Parse.t` can be used. An alternate design would be `val parseAs: (string -> 'a option) * (t -> 'a) -> 'a Parse.t`.

This implementation places a `val parse: t Parse.t` for each IL component next to the corresponding `val layout: t -> Layout.t`. This will make it much easier to keep the layout and parser for each component in sync. This implementation uses a rather more monadic than applicative style of parser, which may be less efficient, but seems to be more maintainable (at least with the present set of parser combinators). This removes a lot of duplicate code, where each previous IL parser had separate (but identical) parsers for common atoms (e.g., constants (see 3d235ec), primimitives (see 87114c1)). Similarly, each previous IL parser had common code for parsing identifiers, handling the fact that each def and use of the same variable in a printed IL program must be mapped to the same ID object (see 80b3014). Overall, these are "best effort" parsers. The intention is that they can be used during development/debugging of IL optimizations. It will be useful to write tiny IL programs (ones much smaller than one gets from even the smallest source SML programs) and send them through the optimization; eg., exactly recreate the example program from a paper. There are some known corner cases, where a printed IL can generate an SML-style comment start; e.g.: val tuple_123: (t_456, t_456) tuple = (**_789, **_789) call L_987 (***_654 ()) This could be handled in the IL pretty-printers at a later date.

In particular, because globals are live for the duration of the program, globalizing an `int list array` (for example) would not be safe-for-space: arbitrarily large lists may be stored in the array and never garbage collected (whereas, when the `int list array` is not globalized, it will be garbage collected when it is no longer live). On the other hand, globalizing an `int array` (with a constant length) is safe-for-space. However, previously, the globalization of a `val a: t array = Array_alloc[t] (l)` was conditioned on the smallness of `t array`. Furthermore, `Type.isSmall` returns `false` for arrays, so no array would be globalized. It is correct to globalize an array if `t` is small; note that to globalize `val a: t array = Array_alloc[t] (l)`, `l` (the length) must be globalized and must, therefore, be a constant and the array is of constant size. (This is Stephen Weeks's relaxed notion of safe-for-space, where the constant factor blowup can be chosen per program.) In practice, it may be better to limit globalization of arrays to ones with "small" length in addition to small element type. This commit allows a `val a: t array = Array_alloc[t] (l)` to be globalized if `-globalize-arrays true`, `t` is small, and `l` is globalized.

Closes MLton/mlton#206. Space-safety prohibits ConstantPropagation from globalizing all arrays and refs that are allocated at most once by a program. In particular, because globals are live for the duration of the program, globalizing an `int list ref` (for example) would not be safe-for-space: an arbitrarily large list may be written to the reference and never be garbage collected (whereas, when the `int list ref` is not globalized, it will be garbage collected when it is no longer live). On the other hand, globalizing an `int ref` is safe-for-space. However, MLton previously used only a very conservative estimation for space safety. Only "small" types may be globalized, where smallness is defined as: fun isSmall t = case dest t of Array _ => false | Datatype _ => false | Ref t => isSmall t | Tuple ts => Vector.forall (ts, isSmall) | Vector _ => false | _ => true Note that no `Datatype` is small; this is conservative (since a recursive datatype could represent unbounded data), but prevents globalizing `bool ref`. Also, no `Array` is small; this is correct (because an `int array ref` should not be globalized), but the globalization of a `val a: t array = Array_alloc[t] (l)` was conditioned on the smallness of `t array`, not the smallness of `t`. It is correct to globalize an array if `t` were small; note that to globalize `val a: t array = Array_alloc[t] (l)`, `l` (the length) must be globalized and must, therefore, be a constant and the array is of constant size. (This is Stephen Weeks's relaxed notion of safe-for-space, where the constant factor blowup can be chosen per program.) This pull request adds support for alternate globalization strategies: * `-globalize-arrays {false|true}`: globalize arrays * `-globalize-refs {true|false}`: globalize refs * `-globalize-small-int-inf {true|false}`:globalize `IntInf` as a small type * `-globalize-small-type {1|0|2|3|4|9}`: strategies for classifying a type as "small": * `0`: constant `false` function (no types considered small) * `1`: no `Datatype` is considered small (original strategy) * `2`: `Datatype`s with all nullary constructors are considered small * `3`: `Datatype`s with all constructor arguments considered small according to strategy `2` are considered small * `4`: Fixed-point analysis of `Datatype`s to determine smallness * `9`: constant `true` function (all types considered small; not safe-for-space) The defaults correspond to the previous behavior. Unfortunately, additional globalization has little to no (positive) effect on benchmarks: MLton0 -- ~/devel/mlton/builds/20190106.115052-gfe996d4/bin/mlton MLton1 -- ~/devel/mlton/builds/20190111.182738-g0847620/bin/mlton -globalize-arrays false -globalize-refs true -globalize-small-type 1 MLton2 -- ~/devel/mlton/builds/20190111.182738-g0847620/bin/mlton -globalize-arrays false -globalize-refs true -globalize-small-type 2 MLton3 -- ~/devel/mlton/builds/20190111.182738-g0847620/bin/mlton -globalize-arrays false -globalize-refs true -globalize-small-type 3 MLton4 -- ~/devel/mlton/builds/20190111.182738-g0847620/bin/mlton -globalize-arrays false -globalize-refs true -globalize-small-type 4 MLton5 -- ~/devel/mlton/builds/20190111.182738-g0847620/bin/mlton -globalize-arrays true -globalize-refs true -globalize-small-type 1 MLton6 -- ~/devel/mlton/builds/20190111.182738-g0847620/bin/mlton -globalize-arrays true -globalize-refs true -globalize-small-type 2 MLton7 -- ~/devel/mlton/builds/20190111.182738-g0847620/bin/mlton -globalize-arrays true -globalize-refs true -globalize-small-type 3 MLton8 -- ~/devel/mlton/builds/20190111.182738-g0847620/bin/mlton -globalize-arrays true -globalize-refs true -globalize-small-type 4 run time ratio benchmark MLton0 MLton1 MLton2 MLton3 MLton4 MLton5 MLton6 MLton7 MLton8 DLXSimulator 1.00 1.00 1.03 1.00 1.00 0.99 1.00 1.01 1.01 checksum 1.00 1.00 1.13 1.14 1.13 1.00 1.12 1.13 1.14 flat-array 1.00 1.00 1.00 1.00 1.01 1.19 1.19 1.19 1.19 hamlet 1.00 1.00 1.02 1.01 1.01 1.00 0.96 0.97 0.97 imp-for 1.00 1.00 1.06 1.05 1.06 1.00 1.05 1.06 1.06 knuth-bendix 1.00 1.00 1.03 1.03 1.03 1.00 1.03 1.03 1.03 lexgen 1.00 0.99 1.05 0.99 1.03 1.04 1.03 1.02 1.07 model-elimination 1.00 1.01 1.02 1.02 1.02 1.00 1.03 1.02 1.03 peek 1.00 1.00 1.03 1.03 1.04 1.00 1.04 1.04 1.04 ray 1.00 1.03 0.99 0.99 1.01 0.99 0.99 0.99 0.98 raytrace 1.00 1.03 1.00 1.02 1.03 0.99 1.00 1.01 1.01 simple 1.00 0.98 0.99 1.00 0.99 0.97 0.97 0.96 0.97 tak 1.00 1.00 1.04 1.03 1.10 1.01 1.02 1.08 1.00 wc-scanStream 1.00 1.00 1.06 1.06 1.06 1.00 1.04 1.06 1.07 Note that `MLton0` and `MLton1` generate identical code (modulo the random magic number), so the slowdowns in `ray` and `raytrace` are noise, which also suggests that slowdowns/speedups of <= 3% are also likely noise. The slowdown in `flat-array` with `-globalize-array true` is explained as follows. The `flat-array` benchmark uses `Vector.tabulate` to allocate a vector that is used for all iterations of the benchmark. With `-globalize-array false`, the array is not globalized, and in SSA/SSA2, we have: x_1212: ((word32, word32) tuple) array = prim Array_alloc((word32, word32) tuple) (global_138 (*0xF4240*)) ... x_757: ((word32, word32) tuple) vector = prim Array_toVector((word32, word32) tuple) (x_1212) ... x_1287: (word32, word32) tuple = prim Vector_sub((word32, word32) tuple) (x_757, x_1283) but with `-globalize-array true`, the array is globalized, and in SSA/SS2, we have: global_490: ((word32, word32) tuple) array = prim Array_alloc((word32, word32) tuple) (global_138 (*0xF4240*)) ... x_757: ((word32, word32) tuple) vector = prim Array_toVector((word32, word32) tuple) (global_490) ... x_1286: (word32, word32) tuple = prim Vector_sub((word32, word32) tuple) (x_757, x_1282) At RSSA, the `Array_toVector` becomes a header update and the array variable is cast/copy-propagated for the vector variable; with `-globalize-arrays false`, we have L_531 (x_1212: Objptr (opt_11)) CReturn {func = {..., target = GC_sequenceAllocate}} = ... OW64 (x_1212, ~8): Word64 := opt_12 ... x_1354: Word32 = XW32 (Cast (x_1212, Objptr (opt_12)), x_1283, 8, 0) x_1353: Word32 = XW32 (Cast (x_1212, Objptr (opt_12)), x_1283, 8, 4) but with `-globalize-arrays true`, we have L_488 (global_490: Objptr (opt_7)) CReturn {func = {..., target = GC_sequenceAllocate}} = ... OW64 (global_490, ~8): Word64 := opt_12 ... x_1353: Word32 = XW32 (Cast (global_490, Objptr (opt_12)), x_1282, 8, 0) x_1352: Word32 = XW32 (Cast (global_490, Objptr (opt_12)), x_1282, 8, 4) Finally, with `-globalize-arrays false`, `x_1212` becomes a local (because the loops to initialize and use the vector are non-allocating): RW32(2): Word32 = XW32 (Cast (RP(0): Objptr (opt_11), Objptr (opt_12)), RW64(0): Word64, 8, 0): Word32 RW32(3): Word32 = XW32 (Cast (RP(0): Objptr (opt_11), Objptr (opt_12)), RW64(0): Word64, 8, 4): Word32 but with `-globalize-arrays true`: RW32(2): Word32 = XW32 (Cast (glob {index = 1, isRoot = true, ty = Objptr (opt_7)}, Objptr (opt_12)), RW64(0): Word64, 8, 0): Word32 RW32(3): Word32 = XW32 (Cast (glob {index = 1, isRoot = true, ty = Objptr (opt_7)}, Objptr (opt_12)), RW64(0): Word64, 8, 4): Word32 The innermost loop of the benchmark goes from indexing a sequence stored in a local (`RP(0)`) to indexing a sequence stored in a global (`GP(1)`). All of the codegens should implement the former by using a hardware register for `RP(0)`, but will implement the latter with a memory read. In light of the above, and related to MLton/mlton#218, it may be beneficial to "deglobalize" object pointer globals; that is, in RSSA functions that have multiple accesses through the same object pointer global (particularly within loops) could be translated to copy the global to a local. The slowdown in `checksum` is less easily explained. The only new objects globalized with `-globalize-small-type 2` as compared to `-globalize-small-type 1` are two `bool ref` objects, corresponding to the `exiting` flag of `basis-library/mlton/exit.sml` and the `staticIsInUse` flag of `basis-library/util/one.sml` used by `Int.fmt`. That small change seems to lead to code layout and cache effects that result in the slowdown, because the assembly code is not substantial different. With `-enable-pass machineSuffle` and `-seed-rand <w>`, one can perturb the code layout and observe that the slowdowns are not universal: MLton0 --

Similarly `tak` with MLton0 and MLton1 have similar running time, but `tak` with MLton3 has a speedup. On the other hand, `flat-array`'s slowdowns with `-globalize-arrays true` are not due to code layout effects. `hamlet` may have a slight speedup with `-globalize-arrays true`, but that is significantly outweighted by the slowdown in `flat-array`. The conclusion is to leave the defaults corresponding to the original behavior.

This will make the contents of `r1` and `r2` useless; however, the values `1` and `2` likely remain useful elsewhere in the program. Hence, for `Ref_ref` and `Weak_new` primitives, it does not suffice to map over the arguments and retain those that are useful. For `Ref_ref` and `Weak_new`, if a `(unit) ref` or `(unit) weak` is being constructred, then ignore the existing arguments and build the object with `unitVar`.

However, when implemented, these primitives do not descend into Array, Ref, or Weak types, so marking the contents of Array, Ref, and Weak types as useful is unnecessary and misses opportunities to eliminate useless components. In particular, while investigating the issue described in 19b07c0, it was observed that the tuple component that was useless but must exist was only forced to exist due to another tuple's corresponding component being made useful by the `deepMakeUseful` triggered by analyzing MLton_equal. However, this was confusing, as the tuple component in question was a `lambdas_nnn` type, which should not be compared by polymorphic equality. Further investigation revealed that it was a `MLton_equal((list_mmm) ref)`, with `list_mmm` corresponding to a list of lambdas. This had the effect of marking *many* transitive closure components as useful, even though they would not actually be used by the implementation of polymorphic equality. This strengthening of Useless has a non-trivial effect on a self-compile: pre.useless: pre.ssa size = 146,403,800 bytes num globals = 37936 num vars in main = 10709 num blocks in main = 2082 num functions in program = 7711 num blocks in program = 231863 num statements in program = 308427 num types in program = 21671 post.useless (old): post.ssa size = 170,454,040 bytes num globals = 19772 num vars in main = 10264 num blocks in main = 2082 num functions in program = 7711 num blocks in program = 230017 num statements in program = 283672 num types in program = 18112 post.useless (new): post.ssa size = 167,373,184 bytes num globals = 19084 num vars in main = 9628 num blocks in main = 2067 num functions in program = 7711 num blocks in program = 229503 num statements in program = 279612 num types in program = 17065 Commit: de3de79f81ba00302d9671939345b159f87856a2 https://github.com/MLton/mlton/commit/de3de79f81ba00302d9671939345b159f87856a2 Author: Matthew Fluet <mat...@gm...> Date: 2018-11-27 (Tue, 27 Nov 2018) Changed paths: M mlton/ssa/useless.fun Log Message: ----------- Cleanup whitespace/formatting Commit: 7ef30bae5476820162d844c75040d6cd940b7153 https://github.com/MLton/mlton/commit/7ef30bae5476820162d844c75040d6cd940b7153 Author: Matthew Fluet <mat...@gm...> Date: 2018-11-28 (Wed, 28 Nov 2018) Changed paths: M doc/guide/src/Useless.adoc M mlton/ssa/useless.fun Log Message: ----------- Eliminate "weirdness with raise/handle" in Useless Previously, the Useless pass would unify all handler arguments so that raise/handle had a consistent calling convention. This seems to be a (long) hold-over from the CPS IL with explicit HandlerPush and HandlerPop statements. Now, allow functions to raise more than is used by a handler, inserting coercion wrapper blocks as necessary. (Something very similar is done in RemoveUnsed.) While this can eliminate useless components of a function's `raises`, it can also require turning a Return.Tail into a Return.NonTail or a Handler.Caller into a Handler.Handle, in order to discard useless components. On a self-compile, compared to previously: * 397 functions go from `raises = Some (exn)` to `raises = Some ()` * 3 calls go from Return.Tail to Return.NonTail * 1571 calls go from Return.Handler to Handler.Handle Commit: f297e456bc836ae9e843d6ff2a96142e43d0676b https://github.com/MLton/mlton/commit/f297e456bc836ae9e843d6ff2a96142e43d0676b Author: Matthew Fluet <mat...@gm...> Date: 2018-11-28 (Wed, 28 Nov 2018) Changed paths: M mlton/ssa/useless.fun Log Message: ----------- Add signatures to Useless.Value.{Exists,Useful} Commit: 602bad4a60cefe749bf01b756997f9684b7dcbfc https://github.com/MLton/mlton/commit/602bad4a60cefe749bf01b756997f9684b7dcbfc Author: Matthew Fluet <mat...@gm...> Date: 2018-12-21 (Fri, 21 Dec 2018) Changed paths: R regression/size2.alpha-linux.ok R regression/size2.amd64-darwin.ok R regression/size2.amd64-freebsd.ok R regression/size2.amd64-linux.ok R regression/size2.amd64-mingw.ok R regression/size2.arm-linux.ok R regression/size2.hppa-hpux.ok R regression/size2.hppa-linux.ok R regression/size2.ia64-hpux.ok R regression/size2.ia64-linux.ok R regression/size2.mips-linux.ok R regression/size2.ok R regression/size2.riscv-linux.ok R regression/size2.s390-linux.ok R regression/size2.sml R regression/size2.sparc-linux.ok R regression/size3.amd64-darwin.ok R regression/size3.amd64-linux.ok R regression/size3.ok R regression/size3.riscv-linux.ok R regression/size3.sml R regression/size3.x86-linux.ok Log Message: ----------- Remove `size2` and `size3` regression tests A forthcoming update to the `Useless` optimization to address MLton/mlton#201 will not force the argument of `MLton_size` to be "deeply useful".

Previously, `MLton_share` was analyzed as a side-effect primitive (it must be preserved by optimizations to perform as the programmer intended) and side-effect primitives have `deepMakeUseful` applied to their arguments; this effectively forced all components of the types flowing to `MLton_share` to be retained. Similarly, although `MLton_eq` and `MLton_size` are not considered side-effect primitives, if the result of `MLton_eq`/`MLton_size` was considered useful, then all components of the types flowing to them were retained. Now, we allow the type upon which these primitives are acting to change as dictated by the rest of the program. In particular, we split the single "useless/useful" lattice element into a pair of "useless/useful" and "not wanted/wanted" lattice elements. Flipping from "not wanted" to "wanted" causes any "not wanted/wanted" element flowing into the current element to be flipped to "wanted" and unifies with any "useless/useful" element flowing into the current element. This has the effect that a component that is "wanted" is also "useful" if any "useful" component flows to it.

Previously, `MLton_touch` was analyzed as a side-effect primitive; side-effect primitives have `deepMakeUseful` applied to their arguments; this effectively forced all components of the types flowing to `MLton_touch` to be retained. However, 'MLton_touch` does not actually use the data structure; it simply keeps the data structure alive. The typical usage of `MLton_touch` for finalizers is to `touch` a reference; hence, it suffices to use `shallowMakeUseful` to make the reference useful, without necessarily making the contents deeply useful.

Because datatypes are recursive, other analyses often conflate all defs and uses of `ConApp`-s; `SplitTypes` allows non-unified instances of a datatype to be analyzed separately.

Unfortunately, it has been difficult constructing a simple source SML program that demonstrates the bug. Nonetheless, here is the essence of the issue: mlton.useless.pre.ssa: lambdas_6803 = Env_24230 global_70971: lambdas_6803 = new Env_24230 L_215729 (x_331531: ((word8) vector, unit) tuple) ... x_331538: (lambdas_6803, (list_161) ref) tuple = (global_70971 (*new Env_24230*), openInbuffers_3) ... x_331537: lambdas_28893 = new Env_44439 (x_331538) ... newIn_2: lambdas_17774 = new Env_48535 (x_331532) call L_215730 (newIn_0 (x_331532, global_100698)) handle _ => L_215665 L_215730 (x_331541: instream_0) tuple_1834: (lambdas_17775, lambdas_4786, lambdas_17774) tuple = (global_70725 (*new Env_24 ... l_37)*), openf_1, newIn_2) ... Useless determines that the `lambdas_6803` component of `x_331538` is useless, but must exist. (Must exist because somewhere else in the program is a useful instance of a `lambdas_6803` component of a `(lambdas_6803, (list_161) ref) tuple` and that tuple flows to a program point with a useless instance of a `lambdas_6803` component of a `(lambdas_6803, (list_161) ref) tuple`; in order to avoid a coercion, Useless requires the `lambdas_6803` component to exist.) To fulfill the obligation for a value of a type that is useless but must exist (and the original value is not otherwise useful and retained by the program), Useless creates a (bogus) value with `MLton_bogus`. In this particular case, retaining the nullary `Env_24230` global would suffice, but, in general, an unbounded amount of work could be saved by using `MLton_bogus` rather than retaining the value from the input SSA program. Also, because the `lambdas_6803` component of `x_331538` is useless, `global_70971` is useless and removed. mlton.useless.post.ssa: lambdas_6803 = Env_24230 bogus_79: lambdas_6803 = prim MLton_bogus(lambdas_6803) () L_215729 (x_331531: (word8) vector) ... x_331538: (lambdas_6803, (list_161) ref) tuple = (bogus_79, openInbuffers_3) ... x_331537: lambdas_28893 = new Env_44439 (x_331538) newIn_2: lambdas_17774 = new Env_48535 (x_331532) call L_217678 (newIn_0 (x_331532, global_100698)) handle _ => L_215665 L_217678 (x_338600: instream_0) tuple_1834: (lambdas_17775, lambdas_4786, lambdas_17774) tuple = (global_70725 (*new Env_24 ... l_37)*), openf_1, newIn_2) ... This portion of the program is unchanged through to removeUnused2. mlton.removeUnused2.pre.ssa2: lambdas_6803 = Env_24230 bogus_79: lambdas_6803 = prim MLton_bogus(lambdas_6803) () L_215729 (x_331531: (word8) vector) ... x_331538: (lambdas_6803, (list_161) ref) tuple = (bogus_79, openInbuffers_3) ... x_331537: lambdas_28893 = new Env_44439 (x_331538) ... newIn_2: lambdas_17774 = new Env_48535 (x_331532) call L_217678 (newIn_0 (x_331532, global_100698)) handle _ => L_215665 L_217678 (x_338600: instream_0) tuple_1834: (lambdas_17775, lambdas_4786, lambdas_17774) tuple = (global_70725 (*new Env_24 ... l_37)*), openf_1, newIn_2) ... The previously eliminated `global_70971` was the only use of `Env_24230` in the program, so `removeUnused2` eliminates it. However, `lambdas_6803` cannot be eliminated because it appears in types and primitives, in particular, `MLton_bogus` for `bogus_79`. mlton.removeUnused2.post.ssa2: lambdas_6803 = bogus_79: lambdas_6803 = prim MLton_bogus(lambdas_6803) () L_215729 (x_331531: (word8) vector) ... x_331538: (lambdas_6803, (list_161) ref) tuple = (bogus_79, openInbuffers_3) ... x_331537: lambdas_28893 = new Env_44439 (x_331538) ... newIn_2: lambdas_17774 = new Env_48535 (x_331532) call L_222685 (newIn_0 (x_331532, global_100698)) handle _ => L_215665 L_222685 (x_343607: instream_0) tuple_1834: (lambdas_17775, lambdas_4786, lambdas_17774) tuple = (global_70725 (*new dummy_1852*), openf_1, newIn_2) ... Again, this portion of the program is unchanged into simplifyTypes. mlton.simplifyTypes.pre.ssa: lambdas_6803 = bogus_79: lambdas_6803 = prim MLton_bogus(lambdas_6803) () L_215729 (x_331531: (word8) vector) ... x_331538: (lambdas_6803, (list_161) ref) tuple = (bogus_79, openInbuffers_3) ... x_331537: lambdas_28893 = new Env_44439 (x_331538) ... newIn_2: lambdas_17774 = new Env_48535 (x_331532) call L_222685 (newIn_0 (x_331532, global_100698)) handle _ => L_215665 L_222685 (x_343607: instream_0) tuple_1834: (lambdas_17775, lambdas_4786, lambdas_17774) tuple = (global_70725 (*new dummy_1852*), openf_1, newIn_2) ... Because there are no constructors for `lambdas_6803`, the cardinality of `lambdas_6803` is determined as `Zero`. This makes the cardinality of `(lambdas_6803, (list_161) ref) tuple` and `Env_44439` both `Zero`. Because the cardinality of `Env_44439` is `Zero`, it is removed from `lambdas_17774` and marked as `Useless`. Finally, a `ConApp` of a `Useless` constructor is considered unreachable code (because such a constructor must be constructed with an argument of cardinality `Zero`, but (`MLton_bogus` not withstanding), no such value could have been constructed by the program). Upon encountering `x_331537: lambdas_28893 = new Env_44439 (x_331538)`, SimplifyTypes stops translating the statements of `L_215729` (and translates the whole block into a statementless/Bug-transfer block). However, SimplifyTypes iterates through the blocks of the program via a DFS, so goes on to translate `L_222685` and encounters a use of `newIn_2` and terminates with `newIn_2 has no varInfo property`. In this particular program, it is not appropriate to conclude that `lambdas_6803` has cardinality `Zero`, because a "value" of such a type is created by `MLton_bogus`. To accommodate such "values", the SimplifyTypes pre-processing is extended to mark any tycon created by `MLton_bogus` as having cardinality `Many`. It does not seem necessary to mark all constituent types of the type created by a `MLton_bogus` as having cardinality `Many`, because a "bogus" values should never be deconstructed. It is not clear that the treatment of unreachable code following the construction of a `Zero` cardinality ConApp is sufficiently robust (because of the DFS that will visit successor blocks), but has not seemed to be problematic.

OpenBSD 6.4 introduced checking that the contents of the hardware stack pointer point into a region of memory mapped with the `MAP_STACK` mmap(2) flag. If, on entry to the kernel, the %rsp on AMD64 or %esp on x86 contain other data, the program will be killed. Without this, executables build with mlton such as `mllex` were dumping core. We support this by: 1) Unconditionally reserving %rsp/%esp in builds targeting OpenBSD. 2) Providing plumbing support for passing arbitrary flags when allocating a signal stack, and passing with the `MAP_STACK` flag down that plumbing when defined. With these changes, building executables for OpenBSD seems to work as expected. Thanks to Matthew Fluet for pointing me at the existing support for reserving %*sp for Cygwin.

request #276 from jasoncarr0/hash-additions Add and use `structure HashTable` and `structure Hash` `structure HashTable` serves as a wrapper to offer a simpler interface for the common usage of a `HashSet.t` as a key-value map. `structure Hash` provides operations to combine word hashes, using a Foller-No-Voll-style hash (multiply then xor). A number of SSA passes have been updated to make use of these, generally reducing code size.

In general, whenever a checked word operation is generated, the `Word_*` and `Word_*CheckP` operations generate distinct assembly instructions. However, only one of these instructions is actually needed, since both perform the same operation and set the same overflow flag, so the generated assembly for a `Word_*CheckP` immediately following an identical `Word_*` operation can be safely removed. Currently, blocks where one `mov` instruction has been hoisted to the front of the block are also recognized.

Originally, an additional case was added to the `elimALRedundant` optimization to handle cases where one move had been hoisted immediately before the corresponding arithmetic operations, but this did not account for cases where one or both moves were hoisted elsewhere in the block. This change introduces a new group of optimizations in the `PeepholeLivenessBlock` section which execute before `moveHoist`. In the future additional optimizations may be added, but at present only the `elimALRedundant` optimization occurs in this group. In addition, the `elimALRedundant` was missing a branch to check for imul2 operations, which has now been added.

Essentially, multiplications by a constant (positive or negative) power of 2 can either erroneously `raise Overflow` or fail to `raise Overflow`. The issue is that the `elimMDPow2` peephole optimization tries to replace multiplications and divisions by powers of 2 by appropriate shifts, adds, and negations. Unfortunately, the conditions for application of the peephole optimization are insufficient for `MLton.newOverflow true`. The implicit assumption in the `elimMDPow2` rewriter is that only signed multiplication may check for overflow and that if a signed multiplication is checked for overflow, then it does so by an immediately following iff-O transfer. Under these assumptions, there are special cases for multiplication by 1, -1, 2, and -2: imul 1, dst => jmp L_nooverflow jo L_overflow jmp L_nooverflow imul -1, dst => neg dst jo L_overflow jo L_overflow jmp L_nooverflow jmp L_nooverflow imul 2, dst => add dst, dst jo L_overflow jo L_overflow jmp L_nooverflow jmp L_nooverflow imul -2, dst => add dst, dst jo L_overflow neg dst jmp L_nooverflow jo L_overflow jmp L_nooverflow Note that multiplication by larger powers of 2 are not rewritten, as the resulting shift and negation will not set the overflow flag in an equivalent manner. If a signed multiplication is not immediately followed by an iff-condition transfer, then multiplication by 1, -1, 2, -2, 2^i (i > 1), and -2^i (i > 1) are rewritten: imul 1, dst => nop imul -1, dst => neg dst1 imul 2, dst => add dst, dst imul -2, dst => add dst, dst neg dst imul 2^i, dst => shl i, dst imul -2^i, dst => shl i, dst neg dst However, with `MLton.newOverflow true`, then a signed multiplication may be followed by a `seto fdst` instruction (followed by a `test fdst, fdst`, followed by a iff-NZ transfer --- this sequence will subsequently be optimized to an iff-O transfer by the `conditionalJump` peephole optimization, but the `conditionalJump` peephole optimization runs later, as part of `peepholeLivenessBlock`). When `imul 1, dst`, `imul 2^i, dst` (i > 1), and `imul -2^i, dst` (i > 1) are rewritten as above, then the subsequent `seto fdst` instruction will not be equivalent. The appropriate fix is unclear. One option is to strengthen the checks in the `elimMDPow2` peephole optimization to disable the rewrite if a subsequent `setcc` instruction would observe the flags. Another option is to delay the `elimMDPow2` peephole optimization until after the `elimALRedundant` peephole optimization has executed. As an aside, note that neither the C codegen nor the LLVM codegen have a similar bug, although their optimizers almost certainly optimize multiplications by powers of 2. This simply adds to the argument that the native codegens should be retired; resources may be better spent improving the C and LLVM codegens than maintaining the native codegens.

There was limited code for preserving instructions that are immediately followed by a `setcc` instruction or a `if` transfer. However, it did not preserve instructions that were immediately followed by an `adc` or `sbb` instruction. This would lead to mis-compilation of `Word64_{add,neg,sub}CheckP` primitives. For example, a `Word64_addCheckP` could initially be translated to: movl src1Lo,tmpLo movl src1Hi,tmpHi addl src2Lo,tmpLo adcl src2Hi,tmpHi seto dst The "tmpLo" destination in the "addl src2Lo,tmpLo" instruction is dead and so the instruction would be eliminated; in turn, the "tmpLo" destination in the "movl src1Lo,tmpLo" instruction is dead and so the instruction would be eliminated. However, although the "tmpHi" destination in the "adcl src2Hi,tmpHi" instruction is dead, the instruction is preserved because of the subsequent "seto" instruction. The end result would be: movl src1Hi,tmpHi adcl src2Hi,tmpHi seto dst which fails to set "dst" appropriately. Now, in addition to preserving instructions that are immediately followed by a `setcc` instruction or an `if` transfer, an instruction immediately preserved by a `adc` or `sbb` instruction is preserved.

However, register allocation unconditionally rewrites `movl $0,dst` as `xorl dst,dst`, leaving code like: xorl tmp,tmp subl srcLo,tmp xorl tmp,tmp sbbl srcHi,tmp However, while a `mov` preserves the condition code flags, a `xorl` instruction clears the CF flag, which leads to incorrect flags being used and set by the `sbb` instruction.

These primitives are exposed to the Basis Library implementation as functions that implicitly raise a primitive exception: val +! = _prim "WordS8_addCheck": int * int -> int; In the XML IR, special care is taken to "remember" the primive exception associated with these primitives in order to implement exceptions correctly. In the SSA, SSA2, RSSA, and Machine IRs, these primitives are treated as transfers, rather than statements. This pull request implements a possibly better implementation of these operations as simple primitives that return a boolean: val +! = _prim "Word8_add": int * int -> int; val +? = _prim "WordS8_addCheckP": int * int -> bool; val +$ = fn (x, y) => let val r = +! (x, y) in if +? (x, y) then raise Overflow else r end This would eliminate the special cases in the XML IR and in the SSA, SSA2, RSSA, and Machine IRs, where the primitives would be treated as statements. Other compilers provide overflow checking via boolean-returning functions: * https://gcc.gnu.org/onlinedocs/gcc/Integer-Overflow-Builtins.html * https://llvm.org/docs/LangRef.html#arithmetic-with-overflow-intrinsics Implementation This patch refactors the primitive checked-arithmetic operations such that the suffix `?` represents a new overflow-checking predicate, a suffix `!` represents the non-overflow-checking variant, and a suffix `$` represents the overflow-checking variant (mnemonic: `$` for "safe" or "expensive"). The behavior of the new `$`-operations is controlled by a compile-time constant, `MLton.newOverflow`. When set to false (the default), the `$`-operations make use of the old-style implicit-`Overflow` primitives. When set to true, the `$`-operations are implemented as an `if`-expression that branches on the result of the corresponding `?`-operation and either raises the `Overflow` exception or returns the result of the corresponding `!`-operation. Finally, the bare operation is aliased to either the `$`-form (with overflow detection enabled) or the `!`-form (with overflow detection disabled). Essentially: val +! = _prim "Word8_add": int * int -> int; val +? = _prim "WordS8_addCheckP": int * int -> bool; val +$ = if MLton.newOverflow then fn (x, y) => let val r = +! (x, y) in if +? (x, y) then raise Overflow else r end else fn (x, y) => ((_prim "WordS8_addCheckP": int * int -> int;) (x, y)) handle PrimOverflow => raise Overflow val + = if MLton.detectOverflow then +$ else +! Note that the checked-arithmetic using `!`- and `$`-operations is careful to perform the `!`-operation before the `$`-operation. With the native-codegens, a new peephole optimization combines the separate unchecked-arithmetic operation and checked-arithmetic-predicate operation into a single instruction. For the C-codgen, the new checked-arithmetic-predicate primitives are translated to uses of the `__builtin_{add,sub,mul}_overflow` intrinsics (which improves upon the previous explicit conditional checking, but requires gcc 5 or greater). Similarly, for the LLVM-codgen, the new checked-arithmetic-predicate primitives are translated to uses of the `{sadd,uadd,smul,umul,ssub,usub}.with.overflow` intrinsics. For both the C- and LLVM-codegens, it is expected that these intrinsics will be combined with the separate unchecked-arithmetic operation. In addition, the `RedundantTests` optimization has been extended to eliminate the overflow test when adding or subtracting 1 with the new primitives. Performance The native-codegen peephole optimization and `RedundantTests` have been mostly sufficient to keep performance on par with the older checked-arithmetic primitives, and in some cases performance has even significantly improved. Below is a summary of the exceptional runtime ratios in the different codegens (both positive and negative): | Benchmark | Native | LLVM | C | |-----------------|--------|------|------| | even-odd | 1.00 | 1.00 | 1.09 | | hamlet | 0.98 | 0.90 | 0.93 | | imp-for | 0.99 | 1.50 | 0.46 | | lexgen | 0.92 | 1.31 | 1.24 | | matrix-multiply | 0.99 | 1.00 | 0.87 | | md5 | 1.06 | 1.01 | 0.97 | | tensor | 1.01 | 1.00 | 0.57 | No benchmarks were consistently worse or better on all codegen, e.g., the `imp-for` benchmark performed exceptionally badly on the LLVM codegen, but was much faster on the C codegen and about even on the native codegen. For this particular benchmark, the cause of the slowdown with the LLVM codegen has yet to be discovered. Similarly, the cause of the slowdown in `lexgen` with the C- and LLVM-codegens is unknown. For the `md5` benchmark, on the other hand, the cause of the slowdown with the native codegen seems to be a failure to eliminate common subexpressions in certain circumstances, which can potentially be improved in the future. Improvements in the C-codegen are likely to be due to the better overflow checking with builtins. Future work The `CommonSubexp` optimization currently handles `Arith` transfers specially; in particular, the result of an `Arith` transfer can be used in common `Arith` transfers that it dominates. This was done so that code like: (n + m) + (n + m) can be transformed to let val r = n + m in r + r end With the new checked-arithmetic-predicate primitives, the computation of the boolean value may be common-subexpr eliminated, but `Case` discrimination will not. This forces the boolean value to be reified and to be discriminated multiple times (though, perhaps `KnownCase` could eliminate subsequent discriminations). Extending `CommonSubexpr` to propagate flow-sensitive relationships at `Case` transfers to the dominated targets could improve the performance `md5` with `MLton.newOverflow true` and potentially improve performance elsewhere as well (e.g., by propagating the results of comparisons as well). Once all performance slowdowns with `MLton.newOverflow true` have been eliminated, it would be desirable to remove the old-style implicit-`Overflow` primitives and `Arith` transfers. This would eliminate many previous instances of special-case code to handle these primitives and transfers. Finally, it may be worth investigating an implementation of the checked-operations via val +$ = fn (x, y) => let val b = +? (x, y) val r = +! (x, y) in if b then raise Overflow else r end rather than val +$ = fn (x, y) => let val r = +! (x, y) in if +? (x, y) then raise Overflow else r end The advantage of calculating the boolean first is that when `x` (or `y`) is a loop variable and `r` will be passed as the value for the next iteration, then both `x` and `r` could be assigned the same location (pseudo-register or stack slot). `x` and `r` cannot share the same location when the boolean is calculated second, because `x` and `r` are both live at the calculation of the boolean. See MLton/mlton#218. This would require reworking the native-codegen peephole optimization.
