command is:
/data/llvm/build/bin/clang-19 -I/data/cutlass/include -I/usr/local/cuda-12.2/include --cuda-gpu-arch=sm_70 -O2 -std=c++17 --cuda-device-only -Xcuda-ptxas -v -o test.s test.cu

compile error:
clang-19: /data/llvm/clang/lib/AST/ExprClassification.cpp:72: Cl clang::Expr::ClassifyImpl(clang::ASTContext&, clang::SourceLocation*) const: Assertion `isPRValue()' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
