Changelog
=========
This document describes changes between tagged Binaryen versions.
To browse or download snapshots of old tagged versions, visit
https://github.com/WebAssembly/binaryen/releases.
Not all changes are documented here. In particular, new features, user-oriented
fixes, options, command-line parameters, usage changes, deprecations,
significant internal modifications and optimizations etc. generally deserve a
mention. To examine the full set of changes between versions, visit the link to
full changeset diff at the end of each section.
Current Trunk
-------------
v90
---
- `local.tee`'s C/Binaryen.js API now takes an additional type parameter for its
local type, like `local.get`. This is required to handle subtypes.
- Added load_splat SIMD instructions
- Binaryen.js instruction API changes:
- `notify` -> `atomic.notify`
- `i32.wait` / `i64.wait` -> `i32.atomic.wait` / `i64.atomic.wait`
- Binaryen.js: `flags` argument in `setMemory` function is removed.
- `atomic.fence` instruction support is added.
- wasm-emscripten-finalize: Don't rely on name section being present in the
input. Use the exported names for things instead.
- Added `mutable` parameter to BinaryenAddGlobalImport.
- Replace BinaryenSIMDBitselect* with BinaryenSIMDTernary* in the C API and add
qfma/qfms instructions.
- Added `offset` parameter to BinaryenSetFunctionTable.
- Add the ability to create multivalue Types in the C and JS APIs.
- Remove named function types. They are replaced by `params` and `results` types
local to each function.
- Binaryen.js can now be compiled to Wasm using the `binaryen_wasm` target.
Unlike the JS variant, the Wasm variant requires asynchronously awaiting the
Wasm blob's instantiation and initialization before being usable, using the
`binaryen.ready` promise, e.g. `binaryen.ready.then(() => ...)`.
v88
---
- wasm-emscripten-finalize: For -pie binaries that import a mutable stack
pointer we internalize this an import it as immutable.
- The `tail-call` feature including the `return_call` and `return_call_indirect`
instructions is ready to use.
v87
---
- Rename Bysyncify => Asyncify
v86
---
- The --initial-stack-pointer argument to wasm-emscripten-finalize no longer
has any effect. It will be removed completely in future release.
v85
---
- Wast file parsing rules now don't allow a few invalid formats for typeuses
that were previously allowed. Typeuse entries should follow this format,
meaning they should have (type) -> (param) -> (result) order if more than one
of them exist.
```
typeuse ::= (type index|name)+ |
(type index|name)+ (param ..)* (result ..)* |
(param ..)* (result ..)*
```
Also, all (local) nodes in function definition should be after all typeuse
elements.
- Removed APIs related to deprecated instruction names in Binaryen.js:
- `get_local` / `getLocal`
- `set_local` / `setLocal`
- `tee_local` / `teeLocal`
- `get_global` / `getGlobal`
- `set_global` / `setGlobal`
- `current_memory` / `currentMemory`
- `grow_memory` / `growMemory`
They are now available as their new instruction names:
`local.get`, `local.set`, `local.tee`, `global.get`, `global.set`,
`memory.size`, and `memory.grow`.
- Add feature handling to the C/JS API with no feature enabled by default.
v84
---
- Generate dynCall thunks for any signatures used in "invoke" calls.
v81
---
- Fix AsmConstWalker handling of string address in arg0 with -fPIC code
v80
---
- Change default feature set in the absence of a target features section from
all features to MVP.
v79
---
- Improve support for side modules
v78
---
- Add `namedGlobals` to metadata output of wasm-emscripten-finalize
- Add support for llvm PIC code.
- Add --side-module option to wasm-emscripten-finalize.
- Add `segmentPassive` argument to `BinaryenSetMemory` for marking segments
passive.
- Make `-o -` print to stdout instead of a file named "-".
v73
---
- Remove wasm-merge tool.
v73
---
- Remove jsCall generation from wasm-emscripten-finalize. This is not needed
as of https://github.com/emscripten-core/emscripten/pull/8255.
v55
---
- `RelooperCreate` in the C API now has a Module parameter, and
`RelooperRenderAndDispose` does not.
- The JS API now has the `Relooper` constructor receive the `Module`.
- Relooper: Condition properties on Branches must not have side effects.
older
-----
- `BinaryenSetFunctionTable` in the C API no longer accepts an array of
functions, instead it accepts an array of function names, `const char**
funcNames`. Previously, you could not include imported functions because they
are of type `BinaryenImportRef` instead of `BinaryenFunctionRef`. #1650
- `BinaryenSetFunctionTable` in the C API now expects the initial and maximum
table size as additional parameters, like `BinaryenSetMemory` does for pages,
so tables can be grown dynamically. #1687
- Add `shared` parameters to `BinaryenAddMemoryImport` and `BinaryenSetMemory`,
to support a shared memory. #1686
