[PATCH] D132144: [Clang][BPF] Support record argument with direct values

[Yonghong Song via Phabricator via cfe-commits]

yonghong-song added a comment.

The compiler only counted the total number of registers won't exceed 5. You could have 5 struct arguments (each one register), or 2 struct arguments (with two registers each) and one integer register.
Whether to pass by value or by reference is a ABI issue, not related to the number of arguments. Checking whether arguments are enough or not is left to BPF backend lowering.
