[PATCH] D76283: [IRBuilder] Use preferred target type for len argument of memory intrinsic functions

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

I guess the logical rule would be that the bit-width of the size has to match the minimum of the bit-widths of the address spaces used with the intrinsic.  (Note that `llvm.memcpy` etc. can take pointers into two different address spaces, potentially of different widths.)  That might be pretty disruptive for existing code, though.
