[ Sylvestre Ledru ] * d/rules: retry the documentation build serially when sphinx's parallel workers die (bare "EOFError" from multiprocessing after a successful compile, trixie amd64/arm64 2026-09-02/03) * 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: Disable sccache on the releases whose glibc is too old for the binary the build host provides. /opt/sccache/sccache comes from mozilla/sccache's latest release and, on s390x (the only arch without a static musl build), needs glibc >= 2.34 since v0.17.0. On focal (glibc 2.31) it cannot even start, and the build died at --start-server with "version `GLIBC_2.34' not found" in stamps/configure. * d/rules: Drop llvm-mt from the install list when it wasn't built. Upstream only builds llvm-mt when it detects libxml2 at configure time; on Ubuntu focal/arm64 the libxml2 symbol check fails and the tool is silently skipped, which made dh_install --fail-missing abort on usr/lib/llvm-22/bin/llvm-mt and usr/bin/llvm-mt-22. * Add a test for the wasi path detection. Thanks Max Gilmour for the work (Closes: #1138702) * d/control.in: libfuzzer-X.Y-dev now depends on libclang-rt-X.Y-dev. -fsanitize=fuzzer links libclang_rt.fuzzer*.a (and libclang_rt.ubsan_standalone.a) from the compiler-rt resource directory, which lives in libclang-rt-X.Y-dev. As it was only a Recommends of libclang-common-X.Y-dev, it was not pulled into build chroots and the link failed. Closes: #1147573. * d/debian-llvm-testsuite.bats: don't skip the libFuzzer compilation test when the compiler-rt libraries are missing, fail instead. * d/libmlir-X.Y.links.in: new, keep a /usr/lib/llvm-X.Y/lib symlink to the libMLIR SONAME now installed in /usr/lib/<triplet>. libmlir-X.Y-dev ships /usr/lib/llvm-X.Y/lib/libMLIR.so as a relative symlink to it and the mlir tools have that directory in their RUNPATH, so both were left dangling. * d/debian-llvm-testsuite.bats: link the fuzzer runtime from the compiler-rt resource directory instead of the removed /usr/lib/llvm-X.Y/lib/libFuzzer.a, and check that it is present. * d/control.in: document that libfuzzer-X.Y-dev is now a dependency package: the fuzzer runtime (libclang_rt.fuzzer*.a) and FuzzedDataProvider.h come from the compiler-rt resource directory in libclang-rt-X.Y-dev, which is what clang links for -fsanitize=fuzzer. This also avoids the empty-binary-package lintian warning. . [ Talha Can Havadar ] * d/p/amdgpu-fix-simulated-trap-continuation-block.diff: cherry-pick llvm/llvm-project@9429a1e809fd (PR #174774, "[AMDGPU] Fix insertSimulatedTrap to return correct continuation block") Fixes a codegen crash on gfx1100/gfx1101/gfx1102 (RDNA3 desktop: RX 7900/7800/7700/7600) where clang aborts with "fatal error: error in backend: Unsupported instruction : <MCInst NNNN ...>" from the AMDGPU AsmPrinter whenever a kernel contains a block that ends in llvm.trap() with no successors — an unlowered pseudo reaches the MC layer. Notably affects pytorch-rocm 2.12's Loss.hip (FTBFS). Reported upstream as llvm/llvm-project#208912. Fix landed on main branch on 2026-01-21 (LLVM 23); release/22.x was cut 8 days before and never received it. This cherry-pick lets 22.1.x carry the fix without waiting for a 22.1.9 or 22.2.0 point release upstream. (Closes: #1141868) . [ Matthias Klose ] * Fix removing RUNPATH, broken in Nov. 2025. Closes: #1142548. * Stop building, shipping and testing the obsolete libFuzzer.a. Closes: #1147573. * Install libmlir shared library in /usr/lib. Closes: #1142778. * libmlir: Remove provides, conflicts and replaces. Not needed. Closes: #1137244.
