[PATCH] D151482: [LV] Add support for minimum/maximum intrinsics

[Anna Thomas via Phabricator via llvm-commits]

anna added a comment.

The original support for fmax/fmin reduction was added here: https://reviews.llvm.org/D87391 and the idea was to rely on semantics of fminnum/fmaxnum since most targets would  crash on fminimum/fmaximum. Now, that we do have the lowerings  for these in more targets, we can introduce a separate intrinsic for propagating NaNs and handling signed zeroes (i.e. support fminimum and fmaximum).
