fixtures/isa/lds.hsaco

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

export PATH="${ROCM_PATH:-${ROCM_HOME:-/opt/rocm}}/lib/llvm/bin:${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.
