Reproduce

aorta sweep run --recipe recipes/sanitizers/daily-consan-lds-dispatch.yaml

Set ROCJITSU_PREBUILT (unpacked rocjitsu bundle supplying rj_waitcheck and the ConSan hook) before running. aorta sets HSA_TOOLS_LIB, HSA_TOOLS_DISABLE_REGISTER, RJ_CONSAN_MODE, RJ_CONSAN_POLICY for you from the recipe's policy block.

Rebuild the fixtures

fixtures/isa/lds.hsaco

a gfx code object built from fixtures/kernels/lds_reduce.hip

export PATH="$(python -c "from aorta.instrumentation.rocm_paths import resolve_rocm_roots; print(resolve_rocm_roots().llvm_bin_dir)"):${PATH}"
mkdir -p recipes/sanitizers/fixtures/isa
hipcc --genco --offload-arch=gfx950 recipes/sanitizers/fixtures/kernels/lds_reduce.hip -o tmp.o
if head -c 24 tmp.o | grep -qF __CLANG_OFFLOAD_BUNDLE__; then clang-offload-bundler --type=o --unbundle --input=tmp.o --targets=hipv4-amdgcn-amd-amdhsa--gfx950 --output=recipes/sanitizers/fixtures/isa/lds.hsaco; else cp tmp.o recipes/sanitizers/fixtures/isa/lds.hsaco; fi && rm -f tmp.o

The conditional matters: --genco emits a raw code object on some ROCm builds and a clang-offload bundle on others, and the recorded digest is of the unbundled object.

fixtures/bin/lds_dispatch

a host repro binary built from fixtures/kernels/lds_dispatch.hip

export PATH="$(python -c "from aorta.instrumentation.rocm_paths import resolve_rocm_roots; print(resolve_rocm_roots().llvm_bin_dir)"):${PATH}"
mkdir -p recipes/sanitizers/fixtures/bin
hipcc --offload-arch=gfx950 -DLDS_HSACO="\"$(pwd)/recipes/sanitizers/fixtures/isa/lds.hsaco\"" recipes/sanitizers/fixtures/kernels/lds_dispatch.hip -o recipes/sanitizers/fixtures/bin/lds_dispatch

The -DLDS_HSACO define is required: it is how the binary learns which code object to load.

The exact invocations the nightly used are in .github/workflows/sanitizers-nightly.yml.

Files

Every file published for this case. Its logs, recipe copy and inputs were pruned for falling outside the nightly's log-retention window. It is not the whole recipe: 2 required inputs are CI-built and excluded by design, listed under artifacts not published with their SHA-256s.
