* Remove implicit conversion operators from Type
Now types must be explicitly converted to uint32_t with Type::getID or
to ValueType with Type::getVT. This fixes #2572 for switches that use
Type::getVT.
* getVT => getSingle

This adds support for the reference type proposal. This includes support
for all reference types (`anyref`, `funcref`(=`anyfunc`), and `nullref`)
and four new instructions: `ref.null`, `ref.is_null`, `ref.func`, and
new typed `select`. This also adds subtype relationship support between
reference types.
This does not include table instructions yet. This also does not include
wasm2js support.
Fixes #2444 and fixes #2447.

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

Adds the ability to create multivalue types from vectors of concrete value
types. All types are transparently interned, so their representation is still a
single uint32_t. Types can be extracted into vectors of their component parts,
and all the single value types expand into vectors containing themselves.
Multivalue types are not yet used in the IR, but their creation and inspection
functionality is exposed and tested in the C and JS APIs.
Also makes common type predicates methods of Type and improves the ergonomics of
type printing.

Fixes #2417

This became noticeable after #2216 which led to some eqz eqz pairs in the test suite.

This helps avoid issues with smaller stack sizes on some OSes.
Should fix the last Mac test failure on emscripten-releases CI (other.test_js_function_names_are_minified, which happens to have massively-nested additions of constants).

- 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

Until the `Abstract` interface gains a notion of SIMD lanes, these optimizations will crash on v128 types.
|

Implement and test the following functionality for SIMD.
- Parsing and printing
- Assembling and disassembling
- Interpretation
- C API
- JS API

This adds a first instance of the rules discussed in #1764 , specifically,
x == y || x > y => x >= y
|

In OptimizeInstructions we canonicalized a const on the right side. This PR adds further canonicalization, of a get to the right, and of sorting by binary and unary op ids. This guarantees fixed orders for small combinations of instructions that can then be pattern-matched in a simple way in future PRs.
|
| |
|
|
|
| |
We need to verify that the reordering is valid if there are side effects.

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.

That method looks through tee_locals and other operations that receive a value and let it flow through them, like a block's final value, etc. It just handled a few such operations, with this PR all of them should be handled.
Also refactor it out of the OptimizeInstructions pass as I think it may be useful for propagating returned constants.

* Optimize shifts of 0.
* Optimize f(x, x) for various f (e.g., x & x => x).

Stuff like x + 5 != 2 => x != -3.
Also some cleanups of utility functions I noticed while writing this, isTypeFloat => isFloatType.

* optimize more simple math operations: mul of 0, or of 0, and of 0, mul of 1, mul of a power of 2, urem of a power of 2
* fix asm2wasm callImport parsing: the optimizer may get rid of the added offset to a function table
* update js builds
|
| |
|
|
| |
* rename WasmType to Type. it's in the wasm:: namespace anyhow, and without Wasm- it fits in better alongside Index, Address, Expression, Module, etc.

(eqz X) and (eqz Y) === eqz (X or Y)
Normally de-morgan's laws apply only to boolean vars, but for the and (but not or or xor) version, it works in all cases (both sides are true iff X and Y have all zero bits).

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).

These are not atomic operations, but are added with the atomic operations to keep from having to define atomic versions of all the sign-extending loads (an atomic zero-extending load + signext operation can be used instead).

* if a block has a concrete final element (or a break with a value), then even if it has an unreachable child, keep it with that concrete type. this means we no longe allow the silly case of a block with an unreachable in the middle and a concrete as the final element while the block is unreachable - after this change, the block would have the type of the final element
* if an if has a concrete element in one arm, make it have that type as a result, even if the if condition is unreachable, to parallel block
* make type rules for brs and switches simpler, ignore whether they are reachable or not. whether they are dead code should not affect how they influence other types in our IR.
