This adds interpreter support for EH instructions. This adds
`ExceptionPackage` struct, which contains info of a thrown exception (an
event tag and thrown values), and the union in `Literal` can take a
`unique_ptr` to `ExceptionPackage`. We need a destructor, a copy
constructor, and an assignment operator for `Literal`, because the union
in `Literal` now has a member that cannot be trivially copied or
deleted.

Since it wasn't easy to support tuples in Asyncify's call support
using temporary functions, we decided to allow tuple-typed globals
after all. This PR adds support for parsing, printing, lowering, and
interpreting tuple globals and also adds validation ensuring that
imported and exported globals do not have tuple types.

This involves replacing `Literal::makeZero` with `Literal::makeZeroes`
and `Literal::makeSingleZero` and updating `isConstantExpression` to
handle constant tuples as well. Also makes `Literals` its own struct
and adds convenience methods on it.

Updates the interpreter to properly flow vectors of values, including
at function boundaries. Adds a small spec test for multivalue return.

This makes the interpreter trap when the signature in `call_indirect`
instruction and that of the actual function in the table mismatch. This
also makes the `wasm-ctor-eval` not evaluate `call_indirect` in case the
signatures mismatch.
Before we only compared the arguments' signature and the function
signature, which was sufficient before we had subtypes, but now the
signature in `call_indirect` and that of the actual function can be
different even if the argument's signature is OK.

This works more like llvm's unreachable handler in that is preserves
information even in release builds.

This means that debugging/tracing can now be enabled and controlled
centrally without managing and passing state around the codebase.

- 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.

This is useful for front-ends which wish to selectively enable or
disable coloring.
Also expose these APIs from the C API.

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

This corresponds to changes made to the initialization procedure in
the spec. It also removes all the heavy initialization work from the
external interface of the interpreter, which is a nice encapsulation
win.
Implementation of the interpretation of the remaining bulk memory
operations and more rigorous tests of that interpretation will come in
a follow-up PR.

This allows us to emit a (potentially modified) target features
section and conditionally emit other sections such as the DataCount
section based on the presence of features.

It was previously part of writing a binary, but changing the number of
segments at such a late stage would not work in the presence of bulk
memory's datacount section. Also updates the memory packing pass
to respect the web's limits on the number of data segments.
|
| |
|
|
|

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

Not being able to evaluate a ctor is different to that ctor
being absent. This is masked a bug in emscripten where we
were spelling the names of the ctors wrong on the command line.

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.

* show a proper error for an empty asm2wasm input
* handle end of input in processExpressions in binary reading
* memory segment sizes should be unsigned
* validate input in wasm-ctor-eval
* update tests

* When we eval a ctor, don't just nop the function body that no longer needs to be executed, also remove the export (as we report the ctor being evalled, and the outside will no longer call it).
* Run the pass to remove unused global things. This can usually remove evalled ctors (unless something else happens to call them, which can't happen normally as LLVM wouldn't use a ctor in another place, but e.g. duplicate function merging might merge a ctor with another function).

The & on the type is the proper convention.

* rename WasmType to Type. it's in the wasm:: namespace anyhow, and without Wasm- it fits in better alongside Index, Address, Expression, Module, etc.

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).

other similar APIs) and fix some ctor-evalling handling of imports, which was incorrect - we need to create fake globals when importing globals, not later, which is too late for initialized globals from imports (#1226)

* fix wasm-ctor-eval, we need to look for the STACKTOP etc. imports, they may not be named, if this build is not with -g
* pack memory after ctor evalling, since we merge it up which is less efficient
* do some useful opts after ctor-evalling, to clean things up

Add wasm-ctor-eval, which evaluates functions at compile time - typically static constructor functions - and applies their effects into memory, saving work at startup. If we encounter something we can't evaluate at compile time in our interpreter, stop there.
This is similar to ctor_evaller.py in emscripten (which was for asm.js).
