I found -malign-data option only affects data alignment in data segment. -malign-data has three options: “compat”,“ abi” and “cacheline”. The default in GCC is ”compat,“ and clang’s behavior is consistent with "abi". And the data alignment on stack and parameters Passing on stack is not affected. This patch only affects the alignment of passing parameter. Should we add an option just like -malign-data?
