# A few steps are necessary to get this build working which makes it slightly
|
|
# nonstandard compared to most other builds.
|
|
#
|
|
# * First, the Rust standard library needs to be recompiled with atomics
|
|
# enabled. to do that we use Cargo's unstable `-Zbuild-std` feature.
|
|
#
|
|
# * Next we need to compile everything with the `atomics` and `bulk-memory`
|
|
# features enabled, ensuring that LLVM will generate atomic instructions,
|
|
# shared memory, passive segments, etc.
|
|
#
|
|
# * Finally, `-Zbuild-std` is still in development, and one of its downsides
|
|
# right now is rust-lang/wg-cargo-std-aware#47 where using `rust-lld` doesn't
|
|
# work by default, which the wasm target uses. To work around that we find it
|
|
# and put it in PATH
|
|
|
|
RUSTFLAGS='-C target-feature=+atomics,+bulk-memory' \
|
|
cargo build --target wasm32-unknown-unknown --release -Z build-std=std,panic_abort
|
|
|
|
# Note the usage of `--no-modules` here which is used to create an output which
|
|
# is usable from Web Workers. We notably can't use `--target bundler` since
|
|
# Webpack doesn't have support for atomics yet.
