Function signatures were previously redundantly stored on Function
objects as well as on FunctionType objects. These two signature
representations had to always be kept in sync, which was error-prone
and needlessly complex. This PR takes advantage of the new ability of
Type to represent multiple value types by consolidating function
signatures as a pair of Types (params and results) stored on the
Function object.
Since there are no longer module-global named function types,
significant changes had to be made to the printing and emitting of
function types, as well as their parsing and manipulation in various
passes.
The C and JS APIs and their tests also had to be updated to remove
named function types.

This creates utility functions for removing module elements: removing
one element by name, and removing multiple elements using a predicate
function. And makes other parts of code use it. I think this is a
light-handed approach than calling `Module::updateMaps` after removing
only a part of module elements.
This also fixes a bug in the inlining pass: it didn't call
`Module::updateMaps` after removing functions. After this patch callers
don't need to additionally call it anyway.

This is the start of a larger refactoring to remove FunctionType entirely and
store types and signatures directly on the entities that use them. This PR
updates BrOnExn and Events to remove their use of FunctionType and makes the
BinaryWriter traverse the module and collect types rather than using the global
FunctionType list. While we are collecting types, we also sort them by frequency
as an optimization. Remaining uses of FunctionType in Function, CallIndirect,
and parsing will be removed in a future PR.

Previously RemoveUnusedModuleElements pass only preserved exported
events and did not preserve events used in `throw` and `br_on_exn`
instructions. This fixes it.

This adds `atomic.fence` instruction:
https://github.com/WebAssembly/threads/blob/master/proposals/threads/Overview.md#fence-operator
This also fix bugs in `atomic.wait` and `atomic.notify` instructions in
binaryen.js and adds tests for them.

This adds support for the event and the event section, as specified in
https://github.com/WebAssembly/exception-handling/blob/master/proposals/Exceptions.md#changes-to-the-binary-model.
Wasm events are features that suspend the current execution and transfer
the control flow to a corresponding handler. Currently the only
supported event kind is exceptions.
For events, this includes support for
- Binary file reading/writing
- Wast file reading/writing
- Binaryen.js API
- Fuzzer
- Validation
- Metadce
- Passes: metrics, minify-imports-and-exports,
remove-unused-module-elements

It looks there's no need to maintain `functions` and `functionImports`
separately.

- Reflected new renamed instruction names in code and tests:
- `get_local` -> `local.get`
- `set_local` -> `local.set`
- `tee_local` -> `local.tee`
- `get_global` -> `global.get`
- `set_global` -> `global.set`
- `current_memory` -> `memory.size`
- `grow_memory` -> `memory.grow`
- Removed APIs related to old instruction names in Binaryen.js and added
APIs with new names if they are missing.
- Renamed `typedef SortedVector LocalSet` to `SetsOfLocals` to prevent
name clashes.
- Resolved several TODO renaming items in wasm-binary.h:
- `TableSwitch` -> `BrTable`
- `I32ConvertI64` -> `I32WrapI64`
- `I64STruncI32` -> `I64SExtendI32`
- `I64UTruncI32` -> `I64UExtendI32`
- `F32ConvertF64` -> `F32DemoteI64`
- `F64ConvertF32` -> `F64PromoteF32`
- Renamed `BinaryenGetFeatures` and `BinaryenSetFeatures` to
`BinaryenModuleGetFeatures` and `BinaryenModuleSetFeatures` for
consistency.

Applies the changes in #2065, and temprarily disables the hook since it's too slow to run on a change this large. We should re-enable it in a later commit.

Mass change to apply clang-format to everything. We are applying this in a PR by me so the (git) blame is all mine ;) but @aheejin did all the work to get clang-format set up and all the manual work to tidy up some things to make the output nicer in #2048

Implement interpretation of remaining bulk memory ops, add bulk memory
spec tests with light modifications, fix bugs preventing the fuzzer
from running correctly with bulk memory, and fix bugs found by the
fuzzer.
|
| |
|
|
|

Adds support for the bulk memory proposal's passive segments. Uses a
new (data passive ...) s-expression syntax to mark sections as
passive.

This renames the following:
- `i32.wait` -> `i32.atomic.wait`
- `i64.wait` -> `i64.atomic.wait`
- `wake` -> `atomic.notify`
to match the spec.

Fixes #1649
This moves us to a single object for functions, which can be imported or nor, and likewise for globals (as a result, GetGlobals do not need to check if the global is imported or not, etc.). All imported things now inherit from Importable, which has the module and base of the import, and if they are set then it is an import.
For convenient iteration, there are a few helpers like
ModuleUtils::iterDefinedGlobals(wasm, [&](Global* global) {
.. use global ..
});
as often iteration only cares about imported or defined (non-imported) things.

Remove the entire memory/table when possible, in particular, when not imported, exported, or used. Previously we did not look at whether they were imported, so we assumed we could never remove them.
Also add a variant that removes everything but functions, which can be useful when reducing a testcase that only cares about code in functions.

* run dfe at the very end, as it may be more effective after inlining
* optimize reorder-functions
* do a final dfe in asm2wasm after all other opts
* make inlining deterministic: std::atomic<T> values are not zero-initialized
* do global post opts at the end of asm2wasm, and don't also do them in the module builder
* fix function type removing
* don't inline+optimize when preserving debug info

We can remove the memory/table (itself, or an import if imported) if they are not used. This is pretty minor on a large wasm file, but when reading small wasts it's very noticeable to have an unused memory and table all the time.

The IR is indeed a tree, but not an "abstract syntax tree" since there is no language for which it is the syntax (except in the most trivial and meaningless sense).

* Move WasmType function implementations to wasm.cpp
* Move Literal methods to wasm.cpp
* Reorder wasm.cpp shared constants back to top
* Move expression functions to wasm.cpp
* Finish moving things to wasm.cpp
* Split out Literal into its own .h/.cpp. Also factor out common wasm-type module
* Remove unneeded/transitive includes from wasm.h
* Add comment to try/check methods
* Rename tryX/checkX methods to getXOrNull
* Add missing include that should fix appveyor build breakage
* More appveyor

Most module walkers use PostWalker<T, Visitor<T>>, let that pattern be
expressed as simply PostWalker<T>

TempRet0 if needed (otherwise we might remove it before we use it)
