* Remove exnref and br_on_exn (#3505)Heejin Ahn2021-01-221-16/+0
| | | This removes `exnref` type and `br_on_exn` instruction.
* Prototype additional f64x2 conversions (#3501)Thomas Lively2021-01-191-0/+7
| | | | As proposed in https://github.com/WebAssembly/simd/pull/383, with opcodes coordinated with the WIP V8 prototype.
* Basic EH instrucion support for the new spec (#3487)Heejin Ahn2021-01-151-3/+7
| | | | | | | | | | | | | | | | | | | | This updates `try`-`catch`-`catch_all` and `rethrow` instructions to match the new spec. `delegate` is not included. Now `Try` contains not a single `catchBody` expression but a vector of catch bodies and events. This updates most existing routines, optimizations, and tests modulo the interpreter and the CFG traversal. Because the interpreter has not been updated yet, the EH spec test is temporarily disabled in check.py. Also, because the CFG traversal for EH is not yet updated, several EH tests in `rse_all-features.wast`, which uses CFG traversal, are temporarily commented out. Also added a few more tests in existing EH test functions in test/passes. In the previous spec, `catch` was catching all exceptions so it was assumed that anything `try` body throws is caught by its `catch`, but now we can assume the same only if there is a `catch_all`. Newly added tests test cases when there is a `catch_all` and cases there are only `catch`es separately.
* Prototype prefetch instructions (#3467)Thomas Lively2021-01-061-0/+18
| | | | As proposed in https://github.com/WebAssembly/simd/pull/352, using the opcodes used in the LLVM and V8 implementations.
* Prototype SIMD extending pairwise add instructions (#3466)Thomas Lively2021-01-051-2/+4
| | | | | | As proposed in https://github.com/WebAssembly/simd/pull/380, using the opcodes used in LLVM and V8. Since these opcodes overlap with the opcodes of i64x2.all_true and i64x2.any_true, which have long since been removed from the SIMD proposal, this PR also removes those instructions.
* MemoryPacking: Preserve segment names (#3458)Sam Clegg2020-12-181-2/+6
| | | | | Also, avoid packing builtin llvm segments names so that segments such as `__llvm_covfun` (use by llvm-cov) are preserved in the final output.
* [GC] Add br_on_cast (#3451)Alon Zakai2020-12-171-1/+14
| | | | | | | | | | | | | | | | The tricky part here, as pointed out by aheejin in my previous attempt, is that we need to know the type of the value we send if the branch is taken. We can normally calculate that from the rtt parameter's type - we are casting to that RTT, so we know what type that is - but if the rtt is unreachable, that's a problem. To fix that, store the cast type on BrOnCast instructions. This includes a test with a br_on_cast that succeeds and sends the cast value, one that fails and passes through the uncast value, and also of one with an unreachable RTT. This includes a fix for Precompute, as noticed by that new test. If a break is taken, with a ref as a value, we can't precompute it - for the same reasons we can't precompute a ref in general, that it is a pointer to possibly shared data.
* Refactor printing code so that printing Expressions always works (#3450)Alon Zakai2020-12-171-0/+7
| | | | | | | | This avoids needing to add include wasm-printing if a file doesn't already have it. To achieve that, add the std::ostream hooks in wasm.h, and also use them when possible, removing the need for the special WasmPrinter object. Also stop printing in "full" (print types on each line) in error messages by default. The user can still get that, as always, using BINARYEN_PRINT_FULL=1 in the env.
* More refactoring of branch utility code to remove boilerplate. (#3448)Alon Zakai2020-12-161-1/+3
| | | | | | | | | | | | | | | | | | | This is almost NFC, but it may emit slightly different IR in cases that don't matter much. Specifically, (block (result i32) ;; can also be unreachable (unreachable) (i32.const 1) ) That can be finalized to have type unreachable or i32, as both are valid. After this PR we should consistently do the same thing in all places. (Either option would be ok - we prefer to keep the type if there is one.) In practice, DCE will remove all the dead code anyhow, leaving no difference to matter. However, the IR is different without DCE, and that may be noticeable in an unoptimized build - but it should have no effect on behavior, just on the binary.
* Prototype SIMD instructions implemented in LLVM (#3440)Thomas Lively2020-12-111-1/+17
| | | | | | - i64x2.eq (https://github.com/WebAssembly/simd/pull/381) - i64x2 widens (https://github.com/WebAssembly/simd/pull/290) - i64x2.bitmask (https://github.com/WebAssembly/simd/pull/368) - signselect ops (https://github.com/WebAssembly/simd/pull/124)
* [GC] Add ref.test and ref.cast (#3439)Alon Zakai2020-12-111-2/+8
| | | | This adds enough to read and write them and test that, but leaves interpreter support for later.
* [GC] Add Array operations (#3436)Alon Zakai2020-12-101-4/+24
| | | | | | | | | | | | | | array.new/get/set/len - pretty straightforward after structs and all the infrastructure for them. Also fixes validation of the unnecessary heapType param in the text and binary formats in structs as well as arrays. Fixes printing of packed types in type names, which emitted i32 for them. That broke when we emitted the same name for an array of i8 and i32 as in the new testing here. Also fix a bug in Field::operator< which was wrong for packed types; again, this was easy to notice with the new testing.
* Read and write data segments names in names section (#3435)Sam Clegg2020-12-091-0/+2
|
* [GC] Add struct.new and start to test interesting execution (#3433)Alon Zakai2020-12-091-2/+10
| | | | | | | | | | | | | | With struct.new read/write support, we can start to do interesting things! This adds a test of creating a struct and seeing that references behave like references, that is, if we write to the value X refers to, and if Y refers to the same thing, when reading from Y's value we see the change as well. The test is run through all of -O1, which uncovered a minor issue in Precompute: We can't try to precompute a reference type, as we can't replace a reference with a value. Note btw that the test shows the optimizer properly running CoalesceLocals on reference types, merging two locals.
* [GC] Add basic RTT support (#3432)Alon Zakai2020-12-081-2/+4
| | | | | | | | | | | | | | | | This adds rtt.canon and rtt.sub together with RTT type support that is necessary for them. Together this lets us test roundtripping the instructions and types. Also fixes a missing traversal over globals in collectHeapTypes, which the example from the GC docs requires, as the RTTs are in globals there. This does not yet add full interpreter support and other things. It disables initial contents on GC in the fuzzer, to avoid the fuzzer breaking. Renames the binary ID for exnref, which is being removed from the spec, and which overlaps with the binary ID for rtt.
* [GC] Add struct.set (#3430)Alon Zakai2020-12-071-2/+6
| | | | | | | | | | Mostly straightforward after struct.get. This renames the value field in struct.get to ref. I think this makes more sense because struct.set has both a reference to a thing, and a value to set onto that thing. So calling the former ref seems more consistent, giving us ref, value. This mirrors load/store for example where we use ptr, value, and ref is playing the role of ptr here basically.
* [GC] Add struct.get instruction parsing and execution (#3429)Alon Zakai2020-12-071-1/+6
| | | | | | | | | | | | | | | | | | | | This is the first instruction that uses a GC Struct or Array, so it's where we start to actually need support in the interpreter for those values, which is added here. GC data is modeled as a gcData field on a Literal, which is just a Literals. That is, both a struct and an array are represented as an array of values. The type which is alongside would indicate if it's a struct or an array. Note that the data is referred to using a shared_ptr so it should "just work", but we'll only be able to really test that once we add struct.new and so can verify that references are by reference and not value, etc. As the first instruction to care about i8/16 types (which are only possible in a Struct or Array) this adds support for parsing and emitting them. This PR includes fuzz fixes for some minor things the fuzzer found, including some bad printing of not having ResultTypeName in necessary places (found by the text format roundtripping fuzzer).
* [TypedFunctionReferences] Implement call_ref (#3396)Alon Zakai2020-11-241-0/+12
| | | | | | | | Includes minimal support in various passes. Also includes actual optimization work in Directize, which was easy to add. Almost has fuzzer support, but the actual makeCallRef is just a stub so far. Includes s-parser support for parsing typed function references types.
* [TypedFunctionReferences] Add Typed Function References feature and use the ↵Alon Zakai2020-11-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | types (#3388) This adds the new feature and starts to use the new types where relevant. We use them even without the feature being enabled, as we don't know the features during wasm loading - but the hope is that given the type is a subtype, it should all work out. In practice, if you print out the internal type you may see a typed function reference-specific type for a ref.func for example, instead of a generic funcref, but it should not affect anything else. This PR does not support non-nullable types, that is, everything is nullable for now. As suggested by @tlively this is simpler for now and leaves nullability for later work (which will apparently require let or something else, and many passes may need to be changed). To allow this PR to work, we need to provide a type on creating a RefFunc. The wasm-builder.h internal API is updated for this, as are the C and JS APIs, which are breaking changes. cc @dcodeIO We must also write and read function types properly. This PR improves collectSignatures to find all the types, and also to sort them by the dependencies between them (as we can't emit X in the binary if it depends on Y, and Y has not been emitted - we need to give Y's index). This sorting ends up changing a few test outputs. InstrumentLocals support for printing function types that are not funcref is disabled for now, until we figure out how to make that work and/or decide if it's important enough to work on. The fuzzer has various fixes to emit valid types for things (mostly whitespace there). Also two drive-by fixes to call makeTrivial where it should be (when we fail to create a specific node, we can't just try to make another node, in theory it could infinitely recurse). Binary writing changes here to replace calls to a standalone function to write out a type with one that is called on the binary writer object itself, which maintains a mapping of type indexes (getFunctionSignatureByIndex).
* Module splitting (#3317)Thomas Lively2020-11-121-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds the capability to programatically split a module into a primary and secondary module such that the primary module can be compiled and run before the secondary module has been instantiated. All calls to secondary functions (i.e. functions that have been split out into the secondary module) in the primary module are rewritten to be indirect calls through the table. Initially, the table slots of all secondary functions contain references to imported placeholder functions. When the secondary module is instantiated, it will automatically patch the table to insert references to the original functions. The process of module splitting involves these steps: 1. Create the new secondary module. 2. Export globals, events, tables, and memories from the primary module and import them in the secondary module. 3. Move the deferred functions from the primary to the secondary module. 4. For any secondary function exported from the primary module, export in its place a trampoline function that makes an indirect call to its placeholder function (and eventually to the original secondary function), allocating a new table slot for the placeholder if necessary. 5. Rewrite direct calls from primary functions to secondary functions to be indirect calls to their placeholder functions (and eventually to their original secondary functions), allocating new table slots for the placeholders if necessary. 6. For each primary function directly called from a secondary function, export the primary function if it is not already exported and import it into the secondary module. 7. Replace all references to secondary functions in the primary module's table segments with references to imported placeholder functions. 8. Create new active table segments in the secondary module that will replace all the placeholder function references in the table with references to their corresponding secondary functions upon instantiation. Functions can be used or referenced three ways in a WebAssembly module: they can be exported, called, or placed in a table. The above procedure introduces a layer of indirection to each of those mechanisms that removes all references to secondary functions from the primary module but restores the original program's semantics once the secondary module is instantiated. As more mechanisms that reference functions are added in the future, such as ref.func instructions, they will have to be modified to use a similar layer of indirection. The code as currently written makes a few assumptions about the module that is being split: 1. It assumes that mutable-globals is allowed. This could be worked around by introducing wrapper functions for globals and rewriting secondary code that accesses them, but now that mutable-globals is shipped on all browsers, hopefully that extra complexity won't be necessary. 2. It assumes that all table segment offsets are constants. This simplifies the generation of segments to actively patch in the secondary functions without overwriting any other table slots. This assumption could be relaxed by 1) having secondary segments re-write primary function slots as well, 2) allowing addition in segment offsets, or 3) synthesizing a start function to modify the table instead of using segments. 3. It assumes that each function appears in the table at most once. This isn't necessarily true in general or even for LLVM output after function deduplication. Relaxing this assumption would just require slightly more complex code, so it is a good candidate for a follow up PR. Future Binaryen work for this feature includes providing a command line tool exposing this functionality as well as C API, JS API, and fuzzer support. We will also want to provide a simple instrumentation pass for finding dead or late-executing functions that would be good candidates for splitting out. It would also be good to integrate that instrumentation with future function outlining work so that dead or exceptional basic blocks could be split out into a separate module.
* MemoryPacking: Properly notice zeroFilledMemory (#3306)Alon Zakai2020-11-021-1/+1
| | | We can only pack memory if we know it is zero-filled before us.
* Prototype new SIMD multiplications (#3291)Thomas Lively2020-10-281-0/+13
| | | | | | | Including saturating, rounding Q15 multiplication as proposed in https://github.com/WebAssembly/simd/pull/365 and extending multiplications as proposed in https://github.com/WebAssembly/simd/pull/376. Since these are just prototypes, skips adding them to the C or JS APIs and the fuzzer, as well as implementing them in the interpreter.
* DWARF: Fix handling of the end of control flow instructions (#3288)Alon Zakai2020-10-271-12/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously when we processed a block for example, we'd do this: ;; start is here (block (result type) ;; end is here .. contents .. ) ;; end delimiter is here Not how this represents the block's start and end as the "header", and uses an extra delimiter to mark the end. I think this is wrong, and was an attempt to handle some offsets from LLVM that otherwise made no sense, ones at the end of the "header". But it turns out that this makes us completely incorrect on some things where there is a low/high pc pair, and we need to understand that the end of a block is at the end opcode at the very end, and not the end of the header. This PR changes us to do that, i.e. ;; start is here (block (result type) .. contents .. ) ;; end is here This fixes a testcase already in the test suite, test/passes/fib_nonzero-low-pc_dwarf.bin.txt where you can see that lexical block now has a valid value for the end, and not a 0 (the proper scope extends all the way to the end of the big block in that function, and is now the same in the DWARF before and after we process it). test/passes/fannkuch3_dwarf.bin.txt is also improved by this. To implement this, this removes the BinaryLocations::End delimeter. After this we just need one type of delimiter actually, but I didn't refactor that any more to keep this PR small (see TODO). This removes an assertion in writeDebugLocationEnd() that is no longer valid: the assert ensures that we wrote an end only if there was a 0 for the end, but for a control flow structure, we write the end of the "header" automatically like for any expression, and then overwrite it later when we finish writing the children and the end marker. We could in theory special-case control flow structures to avoid the first write, but it would add more complexity. This uncovered what appears to be a possible bug in our debug_line handling, see test/passes/fannkuch3_manyopts_dwarf.bin.txt. That needs to be looked into more, but I suspect that was invalid info from when we looked at the end of the "header" of control flow structures. Note that there was one definite bug uncovered here, fixed by the extra } else if (locationUpdater.hasOldExprEnd(oldAddr)) { that is added here, which was definitely a bug.
* Implement i8x16.popcnt (#3286)Thomas Lively2020-10-271-0/+1
| | | | | | As proposed in https://github.com/WebAssembly/simd/pull/379. Since this instruction is still being evaluated for inclusion in the SIMD proposal, this PR does not add support for it to the C/JS APIs or to the fuzzer. This PR also performs a drive-by fix for unrelated instructions in c-api-kitchen-sink.c
* [NFC] `using namespace Abstract` to make matchers more compact (#3284)Thomas Lively2020-10-261-1/+1
| | | | | | | | | This change makes matchers in OptimizeInstructions more compact and readable by removing the explicit `Abstract::` namespace from individual operations. In some cases, this makes multi-line matcher expressions fit on a single line. This change is only possible because it also adds an explicit "RMW" prefix to each element of the `AtomicRMWOp` enumeration. Without that, their names conflicted with the names of Abstract ops.
* Implement v128.{load,store}{8,16,32,64}_lane instructions (#3278)Thomas Lively2020-10-221-1/+32
| | | | | | | These instructions are proposed in https://github.com/WebAssembly/simd/pull/350. This PR implements them throughout Binaryen except in the C/JS APIs and in the fuzzer, where it leaves TODOs instead. Right now these instructions are just being implemented for prototyping so adding them to the APIs isn't critical and they aren't generally available to be fuzzed in Wasm engines.
* Only write explicit names to name section (#3241)Sam Clegg2020-10-151-5/+15
| | | | Fixes: #3226
* Refactor naming convention for functions handling tuples (#3196)Max Graey2020-10-091-1/+1
| | | When there are two versions of a function, one handling tuples and the other handling non-tuple values, the previous naming convention was to have "Single" in the name of the non-tuple handling function. This PR simplifies the convention and shortens function names by making the names plural for the tuple-handling version and singular for the non-tuple-handling version.
* Add static guards for cast and dynCast (#3201)Max Graey2020-10-081-1/+13
|
* GC: Add stubs for the remaining instructions (#3174)Daniel Wirtz2020-09-291-0/+96
| | | NFC, except adding most of the boilerplate for the remaining GC instructions. Each implementation site is marked with a respective `TODO (gc): theInstruction` in between the typical boilerplate code.
* Lower signed binops to unsigned binops when possible (#2988)Max Graey2020-09-281-2/+2
| | | This can unlock further instruction optimizations that do not apply to signed operations.
* GC: Add i31 instructions (#3154)Daniel Wirtz2020-09-241-0/+21
| | | Adds the `i31.new` and `i31.get_s/u` instructions for creating and working with `i31ref` typed values. Does not include fuzzer integration just yet because the fuzzer expects that trivial values it creates are suitable in global initializers, which is not the case for trivial `i31ref` expressions.
* GC: Add ref.eq instruction (#3145)Daniel Wirtz2020-09-211-0/+11
| | | With `eqref` now integrated, the `ref.eq` instruction can be implemented. The only valid LHS and RHS value is `(ref.null eq)` for now, but implementation and fuzzer integration is otherwise complete.
* Initial implementation of "Memory64" proposal (#3130)Wouter van Oortmerssen2020-09-181-18/+23
| | | Also includes a lot of new spec tests that eventually need to go into the spec repo
* Refactor Host expression to MemorySize and MemoryGrow (#3137)Daniel Wirtz2020-09-171-8/+14
| | | Aligns the internal representations of `memory.size` and `memory.grow` with other more recent memory instructions by removing the legacy `Host` expression class and adding separate expression classes for `MemorySize` and `MemoryGrow`. Simplifies related APIs, but is also a breaking API change.
* Implement module and local names in name section (#3115)Daniel Wirtz2020-09-141-1/+5
| | | | | | | | | | | | | | | Adds support for the module and local subsections of the name section plus the respective C and JS APIs to populate and obtain local names. C API: * BinaryenFunctionGetNumLocals(func) * BinaryenFunctionHasLocalName(func, index) * BinaryenFunctionGetLocalName(func, index) * BinaryenFunctionSetLocalName(func, index, name) JS API: * Function.getNumLocals(func) * Function.hasLocalName(func, index) * Function.getLocalName(func, index) * Function.setLocalName(func, index, name)
* Poppy IR wast parsing and validation (#3105)Thomas Lively2020-09-091-0/+3
| | | | | Adds an IR profile to each function so the validator can determine which validation rules to apply and adds a flag to have the wast parser set the profile to Poppy for testing purposes.
* Update reference types (#3084)Daniel Wirtz2020-09-091-0/+2
| | | | | | | Align with the current state of the reference types proposal: * Remove `nullref` * Remove `externref` and `funcref` subtyping * A `Literal` of a nullable reference type can now represent `null` (previously was type `nullref`) * Update the tests and temporarily comment out those tests relying on subtyping
* Implement prototype v128.load{32,64}_zero instructions (#3011)Thomas Lively2020-08-031-1/+3
| | | | | | | | Specified in https://github.com/WebAssembly/simd/pull/237. Since these are just prototypes necessary for benchmarking, this PR does not add support for these instructions to the fuzzer or the C or JS APIs. This PR also renumbers the QFMA instructions that previously used the opcodes for these new instructions. The renumbering matches the renumbering in V8 and LLVM.
* Extend the C- and JS-APIs (#2586)Daniel Wirtz2020-07-221-0/+2

For example: var unary = binaryen.Unary(module.i32.eqz(1)); unary.getOp(...) / .op unary.setOp(...) / .op = ... unary.getValue(...) / .value unary.setValue(...) / .value = ... unary.getType(...) / .type unary.finalize() ... Usage of wrappers is optional, and one can also use plain functions: var unary = module.i32.eqz(1); binaryen.Unary.getOp(unary, ...) ... Also adds comments to all affected functions in case we'd like to generate API documentation at some point.
* Add Expression::dump for use while debugging (#2912)Thomas Lively2020-06-151-0/+3
| | | | | I have found that similar dump functions have been extremely helpful while debugging LLVM. Rather than re-implement this locally whenever I need it, it would be better have this utility upstream.

* Remove `Push` (#2867)Thomas Lively2020-05-221-20/+2
| | | | | | Push and Pop have been superseded by tuples for their original intended purpose of supporting multivalue. Pop is still used to represent block arguments for exception handling, but there are no plans to use Push for anything now or in the future.
* Implement i64x2.mul (#2860)Thomas Lively2020-05-191-0/+1
| | | | This is the only instruction in the current spec proposal that had not yet been implemnented in the tools.
* Implement pseudo-min/max SIMD instructions (#2847)Thomas Lively2020-05-121-0/+4
| | | As specified in https://github.com/WebAssembly/simd/pull/122.
* Fix an old misleading comment (#2738) [ci skip]Alon Zakai2020-04-091-2/+2

* Avoid unnecessary fp$ in side modules (#2717)Alon Zakai2020-03-311-1/+1
| | | | | | | | | | | | | | | | Now that we update the dylink section properly, we can do the same optimization in side modules as in main ones: if the module provides a function, don't call an $fp method during startup, instead add it to the table ourselves and use the relative offset to the table base. Fix an issue when the table has no segments initially: the code just added an offset of 0, but that's not right. Instead, an a __table_base import and use that as the offset. As this is ABI-specific I did it on wasm-emscripten-finalize, leaving TableUtils to just assert on having a singleton segment. Add a test of a wasm file with a dylink section to the lld tests.
* Represent dylink section in IR, so we can update it. (#2715)Alon Zakai2020-03-301-0/+10
| | | | Update it from wasm-emscripten-finalize when we append to the table.
* SIMD integer abs and bitmask instructions (#2703)Thomas Lively2020-03-201-0/+6
| | | | | | Adds full support for the {i8x16,i16x8,i32x4}.abs instructions merged to the SIMD proposal in https://github.com/WebAssembly/simd/pull/128 as well as the {i8x16,i16x8,i32x4}.bitmask instructions proposed in https://github.com/WebAssembly/simd/pull/201.
* Handle multivalue returns in the interpreter (#2684)Thomas Lively2020-03-101-1/+2
| | | | Updates the interpreter to properly flow vectors of values, including at function boundaries. Adds a small spec test for multivalue return.
