Summary: Currently we express umin as `~umax(~x, ~y)`. However, this becomes a problem for operands in non-integral pointer spaces, because `~x` is not something we can compute for `x` non-integral. However, since comparisons are generally still allowed, we are actually able to express `umin(x, y)` directly as long as we don't try to express is as a umax. Support this by adding an explicit umin/smin representation to SCEV. We do this by factoring the existing getUMax/getSMax functions into a new function that does all four. The previous two functions were largely identical. Reviewed By: sanjoy Differential Revision: https://reviews.llvm.org/D50167 llvm-svn: 360159 |
