"mlir-clang" cannot support file name with suffix "cpp"?

[Oxygen-Chu]

If the design is a file with suffix ".cpp" (like test_gemm.cpp), "mlir-clang" will not be executed normally, the generated "test_gemm.mlir" is wrong, and cannot be processed by later command "scalehls-opt" and "scalehls-translate"

"mlir-clang test_gemm.cpp -function=test_gemm -S -memref-fullrank -raise-scf-to-affine > test_gemm.mlir"

Right, currently you cannot directly parse the c++ file generated by scalehls-translate using mlir-clang. You'll need to strip the c++ includes and rename to .c suffix. You may also want to submit an issue to Polygeist to figure out whether this is intended.
