Channing Conger ded7854f09 V8 Bazel Build (#15021)
Alternative approach, we use rusty_v8 for all platforms that its
predefined, but lets build from source a musl v8 version with bazel for
x86 and aarch64 only. We would need to release this on github and then
use the release.

# `rusty_v8` Release Artifacts
This directory contains the Bazel packaging used to build and stage
target-specific `rusty_v8` release artifacts for Bazel-managed consumers.
Current pinned versions:
- Rust crate: `v8 = =146.4.0`
- Embedded upstream V8 source: `14.6.202.9`
The generated release pairs include:
- `//third_party/v8:rusty_v8_release_pair_x86_64_apple_darwin`
- `//third_party/v8:rusty_v8_release_pair_aarch64_apple_darwin`
- `//third_party/v8:rusty_v8_release_pair_x86_64_unknown_linux_gnu`
- `//third_party/v8:rusty_v8_release_pair_aarch64_unknown_linux_gnu`
- `//third_party/v8:rusty_v8_release_pair_x86_64_unknown_linux_musl`
- `//third_party/v8:rusty_v8_release_pair_aarch64_unknown_linux_musl`
- `//third_party/v8:rusty_v8_release_pair_x86_64_pc_windows_msvc`
- `//third_party/v8:rusty_v8_release_pair_aarch64_pc_windows_msvc`
Each release pair contains:
- a static library built from source
- a Rust binding file copied from the exact same `v8` crate version for that
target
Do not mix artifacts across crate versions. The archive and binding must match
the exact pinned `v8` crate version used by this repo.
The dedicated publishing workflow is:
- `.github/workflows/rusty-v8-release.yml`
That workflow currently stages musl artifacts:
- `librusty_v8_release_x86_64-unknown-linux-musl.a.gz`
- `librusty_v8_release_aarch64-unknown-linux-musl.a.gz`
- `src_binding_release_x86_64-unknown-linux-musl.rs`
- `src_binding_release_aarch64-unknown-linux-musl.rs`
During musl staging, the produced static archive is merged with the target's
LLVM `libc++` and `libc++abi` static runtime archives. Rust's musl toolchain
already provides the matching `libunwind`, so staging does not bundle a second
copy.
