[PATCH] D146217: [ValueTracking] Support vscale in computeConstantRange()

[Sander de Smalen via Phabricator via llvm-commits]

sdesmalen added inline comments.


================
Comment at: llvm/lib/Analysis/ValueTracking.cpp:1159-1163
+
+  unsigned AttrMin = Attr.getVScaleRangeMin();
+  // Minimum is larger than vscale width, result is always poison.
+  if ((unsigned)llvm::bit_width(AttrMin) > BitWidth)
+    return ConstantRange::getEmpty(BitWidth);
----------------
Is it possible to create test for this?
