README
wasm-component-ld
This crate contains a binary named wasm-component-ld which is a wrapper around
two pieces of functionality used to produce a WebAssembly Component
- The
wasm-ldlinker driver provided by LLVM - The
wit_component::ComponentEncodertype
This binary will first invoke wasm-ld and then run the componentization
process to produce a final component.
Installation
This repository provides precompiled
binaries of
wasm-component-ld. This repository can also be installed with cargo binstall.
Installations of wasi-sdk have this binary packaged by default in the sysroot
and the Rust wasm32-wasip2 target, upon reaching tier 2, will also come
packaged with this binary included.
This means that while a version can be installed manually it should not be required to do so.
Options
The wasm-component-ld binary is suitable to use as a linker driver during
compilations. For Clang and Rust the wasm32-wasip2 target will automatically
invoke this binary as the linker.
This means that wasm-component-ld forwards most of its arguments to wasm-ld.
Additionally all flags of wasm-ld are supported and forwarded to wasm-ld.
For example you can invoke the linker like wasm-component-ld --max-memory=N ....
The wasm-component-ld binary has a few custom arguments for itself as well
which are not forwarded to wasm-ld and can be explored with -h or --help.
License
This project is triple licenced under the Apache 2/ Apache 2 with LLVM exceptions/ MIT licences. The reasoning for this is:
- Apache 2/ MIT is common in the rust ecosystem.
- Apache 2/ MIT is used in the rust standard library, and some of this code may be migrated there.
- Some of this code may be used in compiler output, and the Apache 2 with LLVM exceptions licence is useful for this.
