[PATCH] D116735: [RISCV] Adjust RISCV data layout by using n32:64 in layout string

[Jessica Clarke via Phabricator via llvm-commits]

jrtc27 added a comment.

That's trying to do `return (unsigned) (((unsigned long long) x * 0xAAAAAAAB) >> 32) >> 1;` for a range of x. Presumably the issue is MULW exists but not MULWHU and friends.
