* [Strings] Add feature flag for Strings proposal (#4766)Alon Zakai2022-06-301-1/+1

* [JS API] Avoid trying to read the offset if segment is passive (#4750)Blaine Bublitz2022-06-242-3/+9
| | | This avoids hitting an assertion.
* Add C and JS API functions for accessing memory info (#4682) Jackson Gardner2022-05-242-0/+44
| | | Based on #3573 plus minor fixes
* Remove externref (#4633)Thomas Lively2022-05-041-9/+9
| | | | | | Remove `Type::externref` and `HeapType::ext` and replace them with uses of anyref and any, respectively, now that we have unified these types in the GC proposal. For backwards compatibility, continue to parse `extern` and `externref` and maintain their relevant C API functions.
* [NFC] Refactor Feature::All to match FeatureSet.setAll() (#4557)Alon Zakai2022-03-311-1/+1
| | | | | | | | | | | As we recently noted in #4555, that Feature::All and FeatureSet.setAll() are different is potentially confusing... I think the best thing is to make them identical. This does that, and adds a new Feature::AllPossible which is everything possible and not just the set of all features that are enabled by -all. This undoes part of #4555 as now the old/simpler code works properly.

* Effects: Differentiate mutable from immutable globals (#4286)Alon Zakai2021-10-291-10/+24
| | | | | | | | | | | | | Similar to what we do with structs, if a global is immutable then we know it cannot interact with calls. This changes the JS API for getSideEffects(). That was actually broken, as passing in the optional module param would just pass it along to the compiled C code, so it was coerced to 0 or 1, and not a pointer to a module. To fix that, this now does module.ptr to actually get the pointer, and this is now actually tested as without a module we cannot compute the effects of a global. This PR also makes the module param mandatory in the JS API, as again, without a module we can't compute global effects. (The module param has already been mandatory in the C++ API for some time.)

* [Wasm GC] ArrayInit support (#4138)Alon Zakai2021-09-102-3/+5
| | | | | | | array.init is like array.new_with_rtt except that it takes as arguments the values to initialize the array with (as opposed to a size and an optional initial value). Spec: https://docs.google.com/document/d/1afthjsL_B9UaMqCA5ekgVmOm75BVFu6duHNsN9-gnXw/edit#
* Use the new module version of EffectAnalyzer (#4116)Alon Zakai2021-08-311-2/+2
| | | | | | | | | | | This finishes the refactoring started in #4115 by doing the same change to pass a Module into EffectAnalyzer instead of features. To do so this refactors the fallthrough API and a few other small things. After those changes, this PR removes the old feature constructor of EffectAnalyzer entirely. This requires a small breaking change in the C API, changing BinaryenExpressionGetSideEffects's feature param to a module. That makes this change not NFC, but otherwise it is.

* [EH] Make tag's attribute encoding detail (#3947)Heejin Ahn2021-06-214-8/+8
| | | | | | | | | This removes `attribute` field from `Tag` class, making the reserved and unused field known only to binary encoder and decoder. This also removes the `attribute` parameter from `makeTag` and `addTag` methods in wasm-builder.h, C API, and Binaryen JS API. Suggested in https://github.com/WebAssembly/binaryen/pull/3946#pullrequestreview-687756523.
* Remove (attr 0) from tag text format (#3946)Heejin Ahn2021-06-193-11/+11
| | | | | | | | This attribute is always 0 and reserved for future use. In Binayren's unofficial text format we were writing this field as `(attr 0)`, but we have recently come to the conclusion that this is not necessary. Relevant discussion: https://github.com/WebAssembly/exception-handling/pull/160#discussion_r653254680
* [EH] Replace event with tag (#3937)Heejin Ahn2021-06-189-81/+81
| | | | | | | | | | | We recently decided to change 'event' to 'tag', and to 'event section' to 'tag section', out of the rationale that the section contains a generalized tag that references a type, which may be used for something other than exceptions, and the name 'event' can be confusing in the web context. See - https://github.com/WebAssembly/exception-handling/issues/159#issuecomment-857910130 - https://github.com/WebAssembly/exception-handling/pull/161
* [Wasm GC] Add experimental support for non-nullable locals (#3932)Alon Zakai2021-06-151-1/+1
| | | | | | | | | | | | | | This adds a new feature flag, GCNNLocals that enables support for non-nullable locals. No validation is applied to check that they are actually assigned before their use yet - this just allows experimentation to begin. This feature is not enabled by default even with -all. If we enabled it, then it would take effect in most of our tests and likely confuse current users as well. Instead, the flag must be opted in explicitly using --enable-gc-nn-locals. That is, this is an experimental feature flag, and as such must be explicitly enabled. (Once the spec stabilizes, we will remove the feature anyhow when we implement the final status of non-nullability. )
* Add SIMDLoadStoreLane get/setters to C/JS API (#3904)Daniel Wirtz2021-05-254-0/+75

* Remove Type ordering (#3793)Thomas Lively2021-05-182-4/+4
| | | | | | | | | As found in #3682, the current implementation of type ordering is not correct, and although the immediate issue would be easy to fix, I don't think the current intended comparison algorithm is correct in the first place. Rather than try to switch to using a correct algorithm (which I am not sure I know how to implement, although I have an idea) this PR removes Type ordering entirely. In places that used Type ordering with std::set or std::map because they require deterministic iteration order, this PR uses InsertOrdered{Set,Map} instead.

* Reorder global definitions in Print pass (#3770)Abbas Mashayekh2021-04-022-8/+8

* Remove passive keyword from data segment parser (#3757)Abbas Mashayekh2021-03-301-2/+2
| | | | | | | | The passive keyword has been removed from spec's text format, and now any data segment that doesn't have an offset is considered as passive. This PR remove that from both parser and the Print pass, plus all tests that used that syntax. Fixes #2339
* Inlining: Always inline single-use functions (#3730)Alon Zakai2021-03-291-1/+1
| | | | | | | | | | | | | | | | This implements emscripten-core/emscripten#13744 Inlining functions with a single use allows us to remove the function afterward. That looks highly beneficial, shrinking every single benchmark in emscripten's benchmark suite, by an average of 2% on the macrobenchmarks and 3.5% on all of them. Speed also improves, although mostly on the microbenchmarks so that might be less realistic. There may be a slight downside to startup time due to emitting larger functions, but given the baseline compilers in VMs these days it seems worth it, as the delay would be just to get to the upper tier. On the benchmark suite the risk seems low. See more details in the PR above.
* [reference-types] Support passive elem segments (#3572)Abbas Mashayekh2021-03-054-29/+37
| | | | | | | | | | | Passive element segments do not belong to any table, so the link between Table and elem needs to be weaker; i.e. an elem may have a table in case of active segments, or simply be a collection of function references in case of passive/declarative segments. This PR takes Table::Segment out and turns it into a first class module element just like tables and functions. It also implements early support for parsing, printing, encoding and decoding passive/declarative elem segments.

|
* Properly use text format type names in printing (#3591)Alon Zakai2021-02-232-6/+6
| | | | | | | | | | | | | | | | | | | This adds a TypeNames entry to modules, which can store names for types. So far this PR uses that to store type names from text format. Future PRs will add support for field names and for the binary format. (Field names are added to wasm.h here to see if we agree on this direction.) Most of the work here is threading a module through the various functions in Print.cpp. This keeps the module optional, so that we can still print an expression independently of a module, which has always been the case, and which I think we should keep (but, if a module was mandatory perhaps this would be a little simpler, and could be refactored into a form that depends on that). 99% of this diff are test updates, since almost all our tests use the text format, and many of them specify a type name but we used to ignore it. This is a step towards a proper solution for #3589
* [EH] Make rethrow's target a try label (#3568)Heejin Ahn2021-02-184-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I was previously mistaken about `rethrow`'s argument rule and thought it only counted `catch`'s depth. But it turns out it follows the same rule `delegate`'s label: the immediate argument follows the same rule as when computing branch labels, but it only can target `try` labels (semantically it targets that `try`'s corresponding `catch`); otherwise it will be a validation failure. Unlike `delegate`, `rethrow`'s label denotes not where to rethrow, but which exception to rethrow. For example, ```wasm try $l0 catch ($l0) try $l1 catch ($l1) rethrow $l0 ;; rethrow the exception caught by 'catch ($l0)' end end ``` Refer to this comment for the more detailed informal semantics: https://github.com/WebAssembly/exception-handling/issues/146#issuecomment-777714491 --- This also reverts some of `delegateTarget` -> `exceptionTarget` changes done in #3562 in the validator. Label validation rules apply differently for `delegate` and `rethrow` for try-catch. For example, this is valid: ```wasm try $l0 try delegate $l0 catch ($l0) end ``` But this is NOT valid: ```wasm try $l0 catch ($l0) try delegate $l0 end ``` So `try`'s label should be used within try-catch range (not catch-end range) for `delegate`s. But for the `rethrow` the rule is different. For example, this is valid: ```wasm try $l0 catch ($l0) rethrow $l0 end ``` But this is NOT valid: ```wasm try $l0 rethrow $l0 catch ($l0) end ``` So the `try`'s label should be used within catch-end range instead.
* [EH] Update C and binaryen.js API for delegate (#3565)Heejin Ahn2021-02-135-8/+71
| | | | | | | | | | This updates C and binaryen.js API to match the new `Try` structure to support `delegate`, added in #3561. Now `try` can take a name (which can be null) like a block, and also has an additional `delegateTarget` field argument which should only be used for try-delegate and otherwise null. This also adds several more variant of `makeTry` methods in wasm-builder. Some are for making try-delegate and some are for try-catch(_all).
* [reference-types] remove single table restriction in IR (#3517)Abbas Mashayekh2021-02-095-10/+29
| | | Adds support for modules with multiple tables. Adds a field for the table name to `CallIndirect` and updates the C/JS APIs accordingly.
* Prototype i32x4.widen_i8x16_{s,u} (#3535)Thomas Lively2021-02-012-32/+32
| | | | | | | | As proposed in https://github.com/WebAssembly/simd/pull/395. Note that the other instructions in the proposal have not been implemented in LLVM or in V8, so there is no need to implement them in Binaryen right now either. This PR introduces a new expression class for the new instructions because they uniquely take an immediate argument identifying which portion of the input vector to widen.
* [GC] Add br_on_func/data/i31 (#3525)Alon Zakai2021-01-282-2/+2
| | | | | | | | This expands the existing BrOnCast into BrOn that can also handle the func/data/i31 variants. This is not as elegant as RefIs / RefAs in that BrOnCast has an extra rtt field, but I think it is still the best option. We already have optional fields on Break (the value and condition), so making rtt optional is not odd. And it allows us to share all the behavior of br_on_* which aside from the cast or the check itself, is identical - returning the value if the branch is not taken, etc.
