[PATCH] D155986: [clang][AMDGPU]: Don't use byval for struct arguments in function ABI

[Yaxun Liu via Phabricator via llvm-commits]

yaxunl added a comment.

Does this patch cause the callee to skip making a local copy of the struct type argument? What if the callee makes changes to the argument? That is a common use case since users assume the function arguments in C/C++/HIP are passed by value.
