I suspect that the version of Sparse you have is causing this problem (although it is just a wild guess). I would suggest installing from git. http://git.kernel.org/pub/scm/devel/sparse/sparse.git The current HEAD is commit 0196afe16a50 ("Merge branch 'riscv'"). I have exercised it quite a lot. For reference, I also use: GCC 15.1.0 from here: https://mirrors.edge.kernel.org/pub/tools/crosstool/ Clang 20.1.8 from here: https://mirrors.edge.kernel.org/pub/tools/llvm/ (Because they are the latest non -rc compilers available there)
