Note 🤖 Claude Opus 5.5 responding on behalf of Theo This is close. Before merge, it needs three changes and green runs. 1. jemalloc page size (must fix). jemalloc takes its page size from the build host. tikv-jemalloc-sys only overrides that for iOS. This build runs on a runner with 4 KiB pages, so the tsc would die at start on a 16 KiB kernel (Asahi, Raspberry Pi 5) or a 64 KiB kernel (RHEL-family and Ubuntu target=${{ matrix.target }}
export "CC_${target//-/_}=musl-gcc"
# jemalloc stops at start when the kernel page is bigger than its build page. arm64 kernels
# use 4, 16 or 64 KiB pages; 2^16 covers all three.

Release: build aarch64-unknown-linux-musl natively on blacksmith-16vcpu-ubuntu-2404-arm (static, non-PIE, as linux-x64), pack @tsc-rs/linux-arm64 and its archive, verify the install on GitHub's ubuntu-24.04-arm runner and publish it with the other platform packages. CI: add blacksmith-16vcpu-ubuntu-2404-arm to the test matrix. npm/trust-setup.sh trusts the new package; the READMEs list the platform.

@t3dotgg rebased on main |
npm tsc-rs 0.1.0 has no @tsc-rs/linux-arm64, so the root README names the first release after 0.1.0 for it. The by-hand pack command in npm/README.md adds the linux-arm64 tsc, as the workflow does. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Note 🤖 Claude Opus 5.5 responding on behalf of Theo Thanks @IAmJSD, this is good work. I read the full diff and the release flow. No new secrets, the publish order stays platform packages first, and I added two commits to the branch:

release.yml: the Build environment step writes CC_<target>=musl-gcc for the matrix target, and JEMALLOC_SYS_WITH_LG_PAGE=16 for aarch64, so the plain and the PGO build of both Linux tsc use them. The header keeps the PGO text and the arm64 platform line. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

npm/trust-setup.shnow includes@tsc-rs/linux-arm64; the READMEs list the platform.Before the next tag
@tsc-rs/linux-arm64is not on npm yet, and trusted publishing can't create it. Shortly before the next tag (npm drops an unused new trust after 2 days), run plainnpm/trust-setup.sh: it publishes the placeholder, adds its trust and leaves the other three packages unchanged. No--relink: v0.1.0 already published from the recreated repo. Otherwise the publish fails on that package.jemalloc page size
jemalloc takes its page size from the build host (4 KiB on the runner) and stops at start on a bigger kernel page (
<jemalloc>: Unsupported system page size). The aarch64 build setsJEMALLOC_SYS_WITH_LG_PAGE=16, so the tsc runs on 4, 16 (Asahi, Raspberry Pi 5) and 64 KiB (RHEL-family, Ubuntu-64k) arm64 kernels. The CI and verify runners all use 4 KiB pages, so they do not test this.Conflict with #8
