================
Comment at: llvm/lib/Target/PowerPC/PPCISelLowering.cpp:10194
   // the permutation mask is complemented with respect to 31.  This is
-  // necessary to produce proper semantics with the big-endian-biased vperm
+  // necessary to produce proper semantics with the big-endian-based vperm
   // instruction.
----------------
nit:
`big-endian-based` -> `big-endian based`
