[PATCH] D101510: Do not merge memcpy if the first source is a parameter of coroutine function

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

Since we are already in the space of finding workarounds, when is the memcpy of the byval parameter introduced? Is it compiler generated? If so, could it be marked volatile there? This would limit the coroutines-specific workaround to coroutine code, which move the tech debt burden from generic LLVM code to coroutines code. That would work.
