Closes: 1138072 1142533
Changes:
llvm-toolchain-21 (1:21.1.8-8) unstable; urgency=medium
.
[ Matthias Klose ]
* Make stonking a known Ubuntu series.
* Build OCaml for stonking.
* libsanitizer: Fix build against latest kernel headers: Closes: #1142533.
* Fix removing RUNPATH, broken in Nov. 2025. Closes: #1138072.
.
[ Sylvestre Ledru ]
* d/rules: set SCCACHE_BASEDIR to keep sccache cache hits across the
changing build directory paths
* d/rules: set SCCACHE_IDLE_TIMEOUT=0 so the sccache server stays alive for
the whole build; otherwise it idles out (default 600s) during the quiet
final-link phase and the libfuzzer step auto-spawns a default-config server
writing to $HOME/.cache/sccache, which fails with HOME=/nonexistent
* d/rules: use the shared GCS sccache cache on arm64 too (add arm64 to the
GCP arch filter)
* d/rules: Fix a make parse error ("recipe commences before first
target") on distributions shipping sccache < 0.14 (e.g. focal): the
sccache SCCACHE_BASEDIR version-guard block was tab-indented, so the
$(warning) line was treated as a recipe. Indent the block with spaces.
* Ship the clang-doc runtime assets (share/clang-doc/, e.g. index.js) in
clang-tools-21 alongside the clang-doc binary instead of only in the
clang-21-doc package. Without them, clang-doc fails with "default
index.js file missing at .../share/clang-doc/index.js".
