[PATCH] D143106: [SDAG] fix miscompiles caused by using ValueTracking matchSelectPattern to create FMINIMUM/FMAXIMUM

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

Can you preserve the match with nsz?

I think we need to just rename FMINNUM to FMIN, and have explicit FMINNUM_IEEE2008 (with snan handling and unspecified -0 vs. 0, or whatever version these were introduced), and FMINNUM_IEEE2019 (with specified +0 vs. 0)
