[David Majnemer via Phabricator via llvm-commits]

majnemer added inline comments.


================
Comment at: lib/Transforms/InstCombine/InstCombineCompares.cpp:3040-3041
+  // Canonicalize minimum operand to LHS of the icmp.
+  if (match(X, m_SMin(m_Specific(Op0), m_Value())) ||
+      match(X, m_SMin(m_Value(), m_Specific(Op0)))) {
+    std::swap(Op0, X);
----------------
Might be nice to have a `m_c_SMin` or something, would simplify this expression and the one bellow.
