  "message": "codegen_ssa: no dbginfo for scalable vec local w/ `-O0`\n\nLLVM uses GlobalISel with -O0 that doesn\u0027t support scalable vectors. It\nnormally falls back to SDAG which does support scalable vectors, but\nthere\u0027s a bug that means that isn\u0027t happening for debuginfo - so\ntemporarily don\u0027t emit debuginfo for scalable vector locals when there\nare no optimisations until that bug is fixed.\n\nSee \u003chttps://github.com/llvm/llvm-project/issues/204585\u003e.\n",
