[PATCH] D123748: [ValueTracking] Added support to deduce PHI Nodes values being a power of 2

[David Li via Phabricator via llvm-commits]

davidxl added inline comments.


================
Comment at: llvm/lib/Analysis/ValueTracking.cpp:2058
+    // be a constant value.
+    if (!match(Start, m_Power2()) || match(Start, m_SignMask()))
+      return false;
----------------
is the power2 check for start done above already?
