--- Comment #1 from Sanjay Patel <spatel+llvm at rotateright.com> ---
I don't see this bug on trunk; tested with:

$ ./clang -v
clang version 6.0.0 (trunk 313258)
Target: x86_64-apple-darwin16.7.0

$ ./clang -O2 -mavx2 castmax.ll -S -o - |grep minsd

        vpminsd %ymm1, %ymm0, %ymm0

Looks fixed in the clang 5.0 release as well:
