[Eli Friedman via Phabricator via llvm-commits]

efriedma added inline comments.


================
Comment at: lib/Target/AArch64/AArch64ISelLowering.cpp:5446
+  // If we can not materialize in immediate field for fmov, check if the
+  // value can be encoded as the immediate operanf of a logical instruction.
+  if (!IsLegal && IsVTLegal)
----------------
"operanf"


================
Comment at: lib/Target/AArch64/AArch64ISelLowering.cpp:5451
+              AArch64_AM::isLogicalImmediate(ImmInt.getZExtValue(),
+                                             VT.getSizeInBits());
 
----------------
I have no idea what isLogicalImmediate does if the RegSize is 16.
