0.15.2-r4

This release republishes the 0.15.2 bootstrap outputs after the Xtensa patch
stack was expanded, regression-tested, and rebuilt across all currently
supported host targets.

Changes

  • Add focused Xtensa fixes for frame scavenging, packed bool-vector stack slots,
    high-group boolean register writeback, and L32R constant-island placement.
  • Add a committed regression harness with Zig repros and Debug-only assembly
    checks that cover the fragile Xtensa backend paths shipped in this release.
  • Fix the Windows zstd bootstrap path so both x86_64-windows-gnu and
    aarch64-windows-gnu host packages now build and ship alongside the macOS
    and Linux packages.

Packaged Targets

  • aarch64-macos-none-baseline
  • x86_64-macos-none-baseline
  • aarch64-linux-gnu-baseline
  • x86_64-linux-gnu-baseline
  • x86_64-windows-gnu-baseline
  • aarch64-windows-gnu-baseline

Notes

  • SHA256SUMS in the release assets contains checksums for all six r4 archives.
  • README.md in the release assets mirrors the current 0.15.2/README.md
    patch catalog for the shipped bootstrap inputs.
